Prepreg carbon fiber, also known as carbon fiber pre-impregnated with resin, offers manufacturers a controlled, consistent starting point for producing high-performance composite parts. Unlike wet layup processes where resin is applied manually, prepreg arrives ready to use with precise fiber-to-resin ratios. But achieving the performance potential of prepreg carbon fiber tape requires proper consolidation during the cure cycle. When consolidation falls short, manufacturers face quality issues that directly impact part performance and production efficiency.
Understanding how to properly consolidate prepreg carbon fiber tape and recognizing when your current process is creating problems is essential for producing aerospace components, automotive parts, sporting goods, and other applications where strength-to-weight ratios and dimensional precision are non-negotiable.
Small-diameter parts like arrow shafts, golf club shafts, and telescoping poles require perfect straightness and uniform wall thickness. When prepreg carbon fiber tape isn’t consolidated properly during cure, resin flows unevenly, and fibers shift position. The result? Parts with straightness variations that force manufacturers to downgrade products to lower-value “Grade B” categories, directly impacting profitability.
The root cause is often inadequate compressive force during the critical consolidation window — when resin viscosity drops and fibers need maximum pressure to maintain position. Non-shrink compaction films provide initial pressure but relax as cure temperatures rise, allowing fibers to move when they should be locked in place.
During the cure cycle, prepreg carbon fiber tape releases volatiles, gases, and vapors from the resin system. If these volatiles can’t escape, they create surface bubbles, dry spots, and delamination between plies. These defects aren’t just cosmetic; they compromise the mechanical properties that make carbon fiber valuable in the first place.
This problem intensifies with certain resin systems that produce higher levels of outgassing. Traditional consolidation methods trap these volatiles under solid compaction layers, creating quality issues that lead to scrap, rework, and reduced yields of premium-grade parts.
Voids, the empty spaces within the resin matrix, represent one of the most serious defects in advanced composites. These gaps reduce tensile strength, create stress concentration points, and shorten part lifespan. In demanding applications like aerospace structures or pressure vessels, voids can lead to catastrophic failure.
Voids form when compressive force is insufficient to push resin completely through fiber layers and eliminate air pockets. The challenge intensifies with prepreg carbon fiber tape because the resin is already partially cured (B-staged), giving manufacturers a narrow processing window to achieve complete fiber wet-out before the resin system fully cross-links.
Unlike non-shrink films that relax as temperatures increase, heat shrink tape for prepreg carbon fiber provides compressive force that increases throughout the cure cycle. This means peak pressure occurs precisely when resin viscosity is lowest, at the critical moment for achieving complete consolidation.
For straightness and dimensional issues, shrink tape, like the 200 Series, applies consistent force across the entire part length. At just 0.002″ thick, this solution allows higher wrapping tension during application while providing additional consolidation during cure. Manufacturers of sporting goods shafts report significant increases in Grade A yields and reduced labor time compared to non-shrink alternatives.
For volatile management, perforated shrink tape allows gases to escape while maintaining compressive force. The perforations actually enable gaseous volatiles to vent, preventing surface bubbles and dry spots. This is particularly valuable for resin systems that produce substantial outgassing during cure.
For void elimination, shrink tape’s increasing compressive force ensures resin penetrates completely between fiber layers. Independent testing published in Composites Science and Technology demonstrated that specimens using Dunstone 220R Hi-Shrink Tape showed significantly reduced voids and delamination compared to specimens without external compaction, resulting in higher tensile strength values.
Success with shrink tape consolidation depends on matching tape properties to your specific prepreg system and part geometry. Key variables include:
The 200 Series is often described as the “Swiss Army knife” for prepreg applications, offering versatility for thin-walled composite parts with options for release coatings and perforations. For applications requiring maximum compressive force, such as thick-walled structures or challenging resin systems, the 500 Series delivers the pressure needed for complete consolidation.
Beyond standard offerings, custom formulations address unique prepreg challenges. Narrow tape widths enable automated winding equipment for complex geometries. Specific shrink percentages optimize force for particular fiber-resin combinations. Silicone release coatings simplify post-cure processing for cosmetically critical parts.
Proper consolidation transforms prepreg carbon fiber tape from a material with potential into parts with predictable, superior performance. When compressive force increases throughout the cure cycle rather than relaxing, manufacturers achieve the dimensional precision, surface quality, and mechanical properties that define premium-grade composites.

Whether you’re producing aerospace tubes, automotive drive shafts, or small-diameter sporting goods, proper tape selection and application technique make the difference between acceptable and exceptional results.

Application Considerations for Prepreg Carbon Fiber Tape Success with shrink tape consolidation depends on matching tape properties to your specific prepreg system and part geometry. Key variables include: Tape thickness – Thin-walled parts (0.001″-0.002″ tape); thick-walled parts (0.003″-0.005″ tape) Shrink percentage – Available from 5% to 20%, depending on the required compressive force Cure temperature – Standard polyester tapes for temperatures up to 165°C; specialized materials for extreme temperatures up to 400°C Release coatings – Enable easy tape removal post-cure without grinding or scraping Perforations – Essential for resin systems with high volatile content The 200 Series is often described as the “Swiss Army knife” for prepreg applications, offering versatility for thin-walled composite parts with options for release coatings and perforations.

Unlike vacuum bagging or autoclaving — which can be time-consuming, expensive, and limited in throughput — composite molding tape provides consistent compressive force throughout the temperature curve, ensuring proper lamination and void-free results.
Here are five real-world examples where composite molding tape transforms manufacturing challenges into competitive advantages.
The Challenge: Composite overwrapped pressure vessels (COPVs) for hydrogen storage operate under extreme internal pressure, often exceeding 10,000 PSI. Any voids or incomplete resin penetration between composite layers creates failure points that compromise structural integrity.
The Solution: Composite molding tape engineered for high compressive force — such as Dunstone’s 200 Series — provides sustained pressure throughout cure cycles reaching 165°C or higher. The tape continues applying force as temperatures rise, unlike non-shrink films that relax. Overlap percentages of 50-75% ensure uniform consolidation across cylindrical geometries, eliminating voids and ensuring complete resin saturation.
The Result: Leak-free vessels with predictable mechanical properties and reduced reject rates for fuel cell and industrial gas applications.
The Challenge: Aerospace composite tubes demand tolerances within ±0.002 inches for structural components and ducting systems. High production volumes require repeatable processes without extensive setup time or autoclaving equipment.
The Solution: Thin composite molding tape — like the 200 Series — balances flexibility with compressive force. At 0.002″ thick, this “Swiss Army knife” solution conforms to tubular geometries while applying consistent pressure. Available with release coatings, the tape separates cleanly without residue and can be applied by hand or automated equipment.
The Result: Manufacturers reduce wrapping time by 40% compared to vacuum bagging while achieving superior dimensional consistency and surface finish, without autoclave capital investment.
The Challenge: Carbon fiber drive shafts must transfer high torque while maintaining perfect rotational balance. Long lengths make uniform consolidation difficult, and automotive production can’t afford lengthy autoclave cycles.
The Solution: Perforated composite molding tape, like Dunstone’s 220R, addresses consolidation and gas evacuation. Perforations allow volatiles to escape, preventing surface blemishes and internal voids. Steep overlap (60-75%) achieves maximum compression along the entire shaft length, with shrink force peaking when resin viscosity is lowest.
The Result: Increased yields of premium-grade parts with superior stiffness, reduced manufacturing time, and elimination of autoclave infrastructure.
The Challenge: Industrial rubber rollers require perfectly uniform surfaces and consistent hardness. During vulcanization at 140°C-180°C, non-shrink materials like woven nylon relax as temperatures rise — precisely when rubber needs maximum compression.
The Solution: Composite molding tape designed for moderate temperatures (140 Series or 200 Series) maintains compressive force throughout vulcanization. Unlike woven nylon, which requires multiple layers and high tension, shrink tape applies increasing force as heat builds. Its thin profile (0.0014″-0.002″) means less material inventory and faster application.
The Result: Consistent roller quality, reduced material waste, faster production cycles, and extended roller lifespan in demanding industrial applications.
The Challenge: Manufacturers of arrow shafts, golf clubs, and fishing rods face intense competition where minor inconsistencies in straightness or wall thickness result in parts being downgraded. Traditional non-shrink films allow uneven resin flow during cure.
The Solution: Thin composite molding tape (100 Series or 140 Series) provides precise low-to-moderate shrink force for small-diameter applications. The tape applies sufficient compression to consolidate prepreg layers without over-compressing. Faster application reduces labor time while more consistent results increase Grade A production.
The Result: Significant improvements in premium-grade to lower-grade shaft ratios, reduced labor and material waste, and consistently straight, high-performance products for sporting goods applications.
Composite molding tape proves its versatility from aerospace structures to sporting goods. When compressive force is applied consistently throughout the cure cycle, manufacturers achieve superior part quality, reduced defects, and increased efficiency.
Success with composite molding tape depends on understanding how variables interact: tape thickness (0.001″-0.005″), cure temperature (165°C-400°C), overlap percentage, wrapping tension, and part diameter all affect compressive force.

In aerospace applications, polyester composite tape consolidates composite materials where performance isn’t negotiable. Carbon fiber fuselage components require void-free lamination to meet strict safety standards. Thermal insulation covers for aircraft systems also rely on polyester composite tape to achieve proper lamination and a consistent surface finish.
Dunstone’s 200 Series Hi-Shrink Tape provides 5-20% shrink force on thin-walled composite tubes and flexible ductwork used in environmental control systems. At 0.002″ thick, it delivers consistent compressive force throughout cure cycles reaching 165°C, eliminating voids that could compromise structural integrity.
Automotive manufacturers leverage polyester composite tape to produce lighter, stronger components. Carbon fiber drive shafts in high-performance vehicles and EV applications require precise consolidation to handle extreme rotational forces. The thin profile of the 100 Series makes it ideal for small-diameter shafts and composite tubes, while carbon fiber rotor sleeves in electric motors benefit from consistent compression that improves mechanical strength and heat dissipation.
Composite rims for performance vehicles demand the same void-free consolidation to withstand impact and rotational stress. Production efficiency matters here — polyester composite tape reduces wrapping time compared to traditional vacuum bagging.
When storage tanks and fluid transfer piping fail, the consequences are severe. Polyester composite tape ensures composite overwrapped pressure vessels (COPVs) and chemical containment systems are properly laminated. The 500 Series Hi-Shrink Tape applies moderate to high shrink force on thick-walled composites, consolidating large-diameter tubes and containment rings. At 0.005″ thick, it delivers the compressive force needed for resin systems that must withstand corrosive chemicals and high-pressure environments. Vulcanized rubber applications for fluid transfer hoses also rely on polyester composite tape’s ability to maintain compression as temperatures rise.
From golf club shafts to arrow shafts and rifle barrels, sporting goods manufacturers use polyester composite tape to produce consistent, high-performance parts at volume. These small-diameter applications benefit from ultra-thin tape options that won’t add unnecessary weight. The 100 Series, at just 0.001″ thick, provides the low to moderate shrink force needed for thin-walled composites while maintaining production speed.
The industries above represent just a fraction of use cases where polyester composite tape solves consolidation challenges.

Buried pipelines transport corrosive materials for decades. Aging lines develop thin walls that compromise safety margins. Downhole sensors must survive harsh conditions while maintaining accuracy. When a pipeline fails in remote or underground locations, the consequences include environmental damage, operational downtime, and significant replacement costs.
This reality explains the growing adoption of carbon fiber in the oil and gas industry for pipeline reinforcement and infrastructure applications. Unlike traditional materials that corrode over time, properly manufactured carbon fiber solutions deliver performance that extends asset life and maintains system integrity.
Carbon fiber’s adoption in oil and gas isn’t trend-driven — it’s driven by physics and economics. Four characteristics make it essential:
Steel pipeline corrosion is the industry’s persistent challenge. Transported materials, soil conditions, and moisture create aggressive chemical environments that degrade metal infrastructure from the inside out. Carbon fiber composites remain chemically inert, making them ideal for reinforcing compromised lines or protecting critical components. For buried applications where inspection is costly and access is limited, this means extended service life without the ongoing corrosion concerns inherent to steel.
Pipeline systems and downhole components experience significant temperature variations, from ambient ground temperatures to elevated process conditions. Carbon fiber maintains structural integrity across these ranges without the thermal expansion mismatches that can compromise reinforcement effectiveness or sensor accuracy.
Carbon fiber’s tensile strength can exceed that of steel by seven times when comparing weight-to-strength ratios. For pipeline reinforcement applications, this enables effective structural support without adding excessive weight to aging infrastructure. In thin-wall pipeline rehabilitation, carbon fiber wrapping restores strength margins while remaining practical for field installation.
Carbon fiber’s low density and flexibility create practical benefits for infrastructure projects. Lighter materials simplify transportation to remote pipeline locations. Composite wrapping systems can conform to existing pipeline geometries, enabling reinforcement without complete line replacement. These characteristics make carbon fiber viable for field repair and rehabilitation applications where traditional methods prove impractical.
Aging pipeline infrastructure frequently develops thin walls from internal corrosion, creating safety and operational concerns. Carbon fiber composite wrapping provides structural reinforcement that restores design margins without requiring complete line replacement. For buried gas lines transporting corrosive materials, composite reinforcement extends operational life while addressing integrity concerns.
This approach proves particularly valuable where pipeline access is limited or replacement costs are prohibitive. The reinforcement can be tailored to specific pipeline conditions, wall thickness requirements, and operating pressures.
Sensor systems and instrumentation in downhole environments require protection from mechanical stress, temperature variations, and chemical exposure. Composite wrapping provides protective barriers that maintain sensor integrity and accuracy throughout demanding operational cycles. These applications demand materials that won’t interfere with sensor functionality while providing necessary environmental protection.
Critical components exposed to corrosive materials or harsh conditions benefit from carbon fiber’s chemical resistance. Protective wrapping and composite barriers extend component life in applications where replacement is costly or operationally disruptive.
Carbon fiber’s material properties are theoretical until manufacturing converts them into actual performance. During curing, resin viscosity drops as temperature increases, creating a critical window where proper compaction is essential. Any voids or inadequate consolidation directly compromise mechanical properties and durability.
For pipeline reinforcement and infrastructure applications, this becomes particularly critical. Composite wraps must achieve uniform compaction around existing geometries. Voids between layers reduce structural performance and create potential failure points. The consolidation method must provide consistent compressive force throughout the cure cycle, ensuring every layer contributes to the final strength.
Pipeline reinforcement projects operate under significant time and cost pressure. Once a buried gas line is exposed for repair, every hour adds expense — excavation equipment, crew costs, production downtime, and regulatory compliance requirements accumulate rapidly. The consolidation method must deliver reliable results consistently, without the trial-and-error that extends project timelines.
Dunstone’s 200 Series Hi-Shrink Tape addresses this requirement directly. The 220R variant provides a repeatable compaction force that ensures consistent composite consolidation across multiple pipeline repairs. When cure conditions remain controlled, the tape delivers predictable shrink percentages and compressive forces, thus eliminating the variability that compromises structural integrity or requires rework.
For applications involving higher cure temperatures or complex geometries, the HT Series Hi-Shrink Tape offers an alternative. Constructed with ETFE layers sandwiching nylon, it delivers reliable compaction to 356°F with strong natural release characteristics and consistent compressive force throughout curing.
This repeatability translates directly to project economics. Crews can apply carbon fiber reinforcement with confidence that the cure cycle will produce the required mechanical properties without inspection failures or costly do-overs. The predictable performance minimizes pipeline exposure time, reduces project risk, and enables efficient scheduling across multiple repair sites.
Understanding carbon fiber in the oil and gas industry means recognizing that consistency in production is key — as is using the right materials. Dunstone partners with manufacturers worldwide to provide efficient, cost-effective, and highly tailored shrink tape solutions. We offer a complete range of Hi-Shrink Tape products, from our adaptable 200 Series to extreme high-temperature HT Series.

Carbon fiber maintains structural integrity across these ranges without the thermal expansion mismatches that can compromise reinforcement effectiveness or sensor accuracy. Superior Strength Under Pressure Carbon fiber’s tensile strength can exceed that of steel by seven times when comparing weight-to-strength ratios. For pipeline reinforcement applications, this enables effective structural support without adding excessive weight to aging infrastructure. In thin-wall pipeline rehabilitation, carbon fiber wrapping restores strength margins while remaining practical for field installation. Field Installation Advantages Carbon fiber’s low density and flexibility create practical benefits for infrastructure projects. Lighter materials simplify transportation to remote pipeline locations. Composite wrapping systems can conform to existing pipeline geometries, enabling reinforcement without complete line replacement. These characteristics make carbon fiber viable for field repair and rehabilitation applications where traditional methods prove impractical. Where Carbon Fiber Performs in Oil and Gas Infrastructure Pipeline Reinforcement and Rehabilitation Aging pipeline infrastructure frequently develops thin walls from internal corrosion, creating safety and operational concerns. Carbon fiber composite wrapping provides structural reinforcement that restores design margins without requiring complete line replacement. For buried gas lines transporting corrosive materials, composite reinforcement extends operational life while addressing integrity concerns. This approach proves particularly valuable where pipeline access is limited or replacement costs are prohibitive. The reinforcement can be tailored to specific pipeline conditions, wall thickness requirements, and operating pressures. Downhole Applications Sensor systems and instrumentation in downhole environments require protection from mechanical stress, temperature variations, and chemical exposure. Composite wrapping provides protective barriers that maintain sensor integrity and accuracy throughout demanding operational cycles. These applications demand materials that won’t interfere with sensor functionality while providing necessary environmental protection. Component Protection Critical components exposed to corrosive materials or harsh conditions benefit from carbon fiber’s chemical resistance. Protective wrapping and composite barriers extend component life in applications where replacement is costly or operationally disruptive. The Manufacturing Reality: Where Performance Is Won or Lost Carbon fiber’s material properties are theoretical until manufacturing converts them into actual performance. During curing, resin viscosity drops as temperature increases, creating a critical window where proper compaction is essential. Any voids or inadequate consolidation directly compromise mechanical properties and durability. For pipeline reinforcement and infrastructure applications, this becomes particularly critical. Composite wraps must achieve uniform compaction around existing geometries. Voids between layers reduce structural performance and create potential failure points. The consolidation method must provide consistent compressive force throughout the cure cycle, ensuring every layer contributes to the final strength. Enabling Reliable Infrastructure Solutions Pipeline reinforcement projects operate under significant time and cost pressure. Once a buried gas line is exposed for repair, every hour adds expense — excavation equipment, crew costs, production downtime, and regulatory compliance requirements accumulate rapidly. The consolidation method must deliver reliable results consistently, without the trial-and-error that extends project timelines. Dunstone’s 200 Series Hi-Shrink Tape addresses this requirement directly. The 220R variant provides a repeatable compaction force that ensures consistent composite consolidation across multiple pipeline repairs. When cure conditions remain controlled, the tape delivers predictable shrink percentages and compressive forces, thus eliminating the variability that compromises structural integrity or requires rework. For applications involving higher cure temperatures or complex geometries, the HT Series Hi-Shrink Tape offers an alternative. Constructed with ETFE layers sandwiching nylon, it delivers reliable compaction to 356°F with strong natural release characteristics and consistent compressive force throughout curing. This repeatability translates directly to project economics. Crews can apply carbon fiber reinforcement with confidence that the cure cycle will produce the required mechanical properties without inspection failures or costly do-overs. The predictable performance minimizes pipeline exposure time, reduces project risk, and enables efficient scheduling across multiple repair sites.

Learn what makes high performance heat shrink tape different, and why the tailored shrink curve matters.", "content": "Not all heat shrink tape performs the same when it matters most. The term “high performance heat shrink” isn’t marketing language; it describes how shrink tape behaves during the critical curing phase when resin viscosity drops and maximum compaction is essential. While traditional compaction films apply pressure only during wrapping, high performance heat shrink tape is engineered to deliver increasing force precisely when your composite part needs it.
For decades, manufacturers have relied on standard compaction films like cellophane, woven nylon, and polypropylene to consolidate composite parts during cure. These materials work by applying tension during the wrapping process; operators wrap them tightly around the part, creating initial compression through mechanical tension alone.
The challenge emerges as soon as curing begins. These traditional films relax as temperatures rise, losing compressive force right when it’s needed most. At room temperature during layup, resin viscosity is at its highest and is difficult to move. But as the part enters the oven and temperatures climb toward 120-165°C, the resin reaches its lowest viscosity point and begins to flow. This is the critical moment when maximum compression should be applied to eliminate voids, remove volatiles, and ensure proper lamination between layers. Traditional films, however, provide their weakest compression at this exact phase.
High performance heat shrink tape functions on an entirely different principle. Rather than relying solely on application tension, these tapes are engineered with a tailored shrink curve that matches the thermal profile of composite curing processes.
Dunstone’s Hi-Shrink Tape begins shrinking at approximately 70°C and reaches maximum compressive force in the 120-180°C range — precisely when resin viscosity drops and flow occurs. This isn’t coincidental. The molecular structure of the tape material is designed to create this behavior, delivering a compression curve that rises as temperature increases rather than falling away.
The force delivered depends on several engineering variables. High performance heat shrink tape can apply anywhere from 1.65 to 21.64 pounds of shrink force, with the exact amount determined by tape thickness, shrink percentage, application tension, and overlap. Tape thickness ranges from 0.001 inch (1 mil) for applications requiring minimal force to 0.005 inch (5 mils) for parts demanding maximum compaction. Shrink percentages typically range from 5% to 20%, with higher percentages generating greater compressive force.
Material composition plays an equally critical role in performance. Polyester-based tapes (100, 140, 200, 300, and 500 Series) handle cure temperatures up to 165°C and serve the majority of composite applications, from automotive drive shafts to aerospace components. For higher temperature requirements, ETFE-based tapes extend performance to 180°C, while polyimide materials enable shrink behavior at temperatures reaching 400°C for advanced thermoplastic systems like PEEK and PPS.
This engineered thermal behavior translates directly to part quality. As the tape shrinks during cure, it eliminates voids between composite layers, removes air pockets from the resin matrix, and ensures a consistent surface finish across the entire part. The continuous compression throughout the cure cycle prevents the formation of dry spots and foreign object debris that compromise mechanical strength.
Because high performance heat shrink tape is significantly thinner than traditional compaction materials while delivering superior force, manufacturers use less material overall. A 0.002-inch polyester tape at 50% overlap can outperform multiple layers of thicker materials and cheaper non-shrink films, reducing both material costs and removal time after cure.
Applications span from small-diameter sporting goods like arrow shafts and golf clubs to large composite tubes, pressure vessels, and high-voltage electrical coils. In each case, the tailored compression curve ensures optimal consolidation regardless of part geometry or resin system.
High performance heat shrink tape earns its designation through measurable engineering characteristics, specifically, the ability to apply increasing compressive force during the phase when composite parts are most vulnerable to defects. The tailored shrink curve that begins at 70°C and peaks at optimal curing temperatures represents decades of material science development focused on matching tape behavior to resin cure profiles.
For manufacturers evaluating compaction solutions, the question isn’t whether their current process “works” — it’s whether a material engineered for peak performance during cure could deliver better results. Testing high performance heat shrink tape with your resin system in your specific application is how you verify the difference.

With companies devoting vast resources to this need, it follows that the materials themselves must be top-notch — especially when it comes to the consolidation of composites and resins. Even minor shortcomings in materials can lead to failure.
The first step in ensuring consistent composite part quality is understanding the composite itself. There are many grades of composites. For example, carbon fiber can vary widely based on its precursor material, its mechanical properties, and its performance capabilities after curing. Kevlar, too, varies based on how it will be used; often it’s associated with defense applications, but it has industrial uses as well that require different grades. Even fiberglass has different grades according to its use case.
The resin system being used in conjunction with the composite material also plays a critical role in part performance and influences the manufacturing process. Vinyl esther, epoxy, polyester, and phenolic resins are all common with composites, offer different performance characteristics, and will influence production methods. Additionally, new resin systems are being developed — such as UV-cured resin systems — that are incompatible with previous production processes.
There are many methods for compaction of composite materials and resins — with and without heat being applied. Examples include cellophane, woven nylon, various shrink films, and shrink tape. These materials are applied ahead of a curing process, such as using a vacuum bag, an autoclave, or an oven.
While each of these compaction solutions and processes has its purpose, overall production must be considered as well. For example, many of these compaction materials don’t shrink on their own when heat is applied — compaction force must be created via tension and overwrapping, most of which has to be done by hand. This translates into more material being used as well as labor.
Even automation must be factored in. Shrink tapes are often usable in automated processes, such as with traverse winders and other equipment types. Understanding how the tape will be applied via these automated systems is critical to performance outcomes.
The heat source being used for curing also makes a production impact, requiring more time to move parts in and out of the unit, such as with an autoclave or oven, or manually applying heat, such as with a heat gun.
Understanding the pressures that your parts will be exposed to is critical here. Everything mentioned thus far will impact the ability of those parts to withstand pressure and other physical stressors — whether it’s the isolated, infrequent use of a sporting goods pole or prolonged exposure to heat and pressure in oil and gas fluid transfer.
With a clear understanding of everything that has been discussed thus far, you’ll be able to implement a consistent production process that ensures the core composite material, corresponding resin system, and curing method are synergistic and will result in the best possible outcome. However, it is still worth describing the potential risks associated with composites. If you begin to see any of these in your production process, you may need to make some adjustments:

However, it is still worth describing the potential risks associated with composites. If you begin to see any of these in your production process, you may need to make some adjustments: Voids and porosity — These are usually caused by a failure in the compaction of the composite material and resin. Insufficient pressure or heat means that the resin is unable to penetrate into the fibers or layers of the composite, so it is not filled, or gas is unable to escape the layup. Foreign object debris (FOD) — This is the presence of unwanted material in the layup. This can occur for numerous reasons, but compaction is critical in forcing those materials out of the composite. Delamination — This is the separation of layers in the composite material. Insufficient compaction is a leading cause here. Surface finish issues — Inconsistent compaction or misapplication of the materials can lead to variance in the surface finish, which may lead to part performance issues or rejection during quality inspections.

For shrink tapes, this release material is typically added to one or both sides of the tape depending on the application, allowing for the easy removal of the tape from the underlying part without leaving any material or residue.
In many instances, this is preferable to non-release-coated shrink solutions because uncoated materials not only leave material behind but also require more manpower and production time to remove (it’s often done by hand). Unless the application specifically calls for the tape to be left on, if the tape will be acting as an insulator, the shrink tape or film will most likely need to be removed.
However, applications differ from one to the next — what works well for one resin system, composite material, compaction film, and curing temperature combination might not work as well for others.
Biaxially-oriented polypropylene — or BOPP — is a common shrink film used by many manufacturers around the world. Recently, Dunstone worked with a company producing parts for an electrical application. While BOPP does provide compaction, this particular application required greater force in order to avoid moisture getting into the part.
The company decided to utilize Dunstone 220R — a PTFE-release-coated version of the 200 Series with up to 20% shrink. The 200R tape resulted in a 100% success rate for parts produced — no moisture was found in the parts. However, the release-coated tape was sticking to the parts, requiring the customer’s production team to manually remove the residue.

Examples include NASA’s Hi-Rate Composite Aircraft Manufacturing (HiCAM) project, which partners with the composite industry “to increase the rate of composite aircraft manufacturing, reduce costs, and improve performance.”
Concurrently, there is a notable issue with composites — they are often not recycled at the end of their lifespan. In the U.K., partnerships and programs — such as HVM Catapult — have sprung up to accelerate the recyclability and reusability of composites while also innovating more sustainable variations of common composite materials.
Today, manufacturers primarily use three methods for the production of composite parts: 1) autoclaves, 2) vacuum bagging, and 3) shrink films and tapes. All three apply pressure over time in order to consolidate composite materials/prepregs and resin in order to cure them and produce a part with a consistent finish and, ideally, no voids or defects.
There are a few challenges with these methods that get in the way of faster production. First, autoclaves are expensive and can only hold so many parts during their operating cycles. So, unless a manufacturer is prepared to spend tens of thousands (or more) on numerous autoclaves, going this route to streamline high-rate composite manufacturing won’t be ideal.
Vacuum bagging is another alternative to consolidate composite parts, but it is also an extremely cumbersome process. Additionally, vacuum-bagging is limited to certain pressure levels, so it may not be ideal for applications that require extreme pressure or high temperature during curing.
Additionally, composites can be manufactured much more quickly by eliminating the need for autoclave curing and allowing parts to be welded instead of mechanically fastened or bonded. Advanced welding techniques such as resistance and induction welding enable rapid, localized heating for joining components in minutes. These processes are highly automation-friendly, reduce part count, and streamline assembly by supporting integrated, net-shape designs. Together, these benefits cut cycle times, lower energy use, and make high-rate production of composite parts more viable.
While an autoclave or vacuum-bagging process may be ideal for some applications, countless composite parts can benefit from shrink tape. There are numerous reasons for this:

Learn more about the key differences between shrink tape, autoclaves, and vacuum-bagging in this helpful overview. Additionally, composites can be manufactured much more quickly by eliminating the need for autoclave curing and allowing parts to be welded instead of mechanically fastened or bonded.

Together, these benefits cut cycle times, lower energy use, and make high-rate production of composite parts more viable. Why Shrink Tape is Ideal for High-Rate Composite Manufacturing While an autoclave or vacuum-bagging process may be ideal for some applications, countless composite parts can benefit from shrink tape. There are numerous reasons for this: Flexibility in application — One of the key advantages of shrink tape is that it can be applied in a variety of ways depending on the part and the performance needed from it. For example, if greater compaction is required based on the material and resin system, the tape simply needs to be applied with more overwrap, additional layers, or more tension. Learn more about application techniques here. Automation capability — Whereas autoclaves and vacuum-bagging require manual effort (putting parts inside these systems, taking them out, etc.), shrink tape can be automatically applied to parts through the use of winders. This rapidly accelerates the process of applying the tape, allowing for higher throughput. Lower cost — Shrink tape is exceptionally thin, yet thanks to its design and composition, it applies significant shrink force to underlying parts. As a result, manufacturers spend less buying shrink tape than investing thousands into autoclave systems and other tools. All that is needed is an oven to cure the composite, which is much less expensive than an autoclave, depending on its size. Customization — Shrink tape is extremely customizable. If greater shrink force, a higher overall shrink percentage, specific thickness, or any other property needs to be modified, shrink tape is fully capable of handling adjustments. This further streamlines production processes and ensures the tape works exactly as needed. Availability — At Dunstone, dozens of Hi-Shrink Tape products are in-stock and ready to ship. We keep a full suite of Hi-Shrink Tapes ready, whether it’s our thinnest 100 Series tape, our 200 Series (a “Swiss Army knife” solution for numerous applications), our high-force 500 Series, or our X Series industry-leading high-temperature solution, we have the shrink tape you need ready to go.

For companies using composite materials such as carbon fiber in their parts, compaction of the composite material is one of these key processes. Shrink tape for composites is one of the most common solutions, alongside autoclaves and vacuum bagging.
However, when it comes to using shrink tape, part design is a critical detail that cannot be ignored or deprioritized. The diameter of parts, especially those with a small cylindrical structure, significantly influences the type of shrink tape needed. Here, we’ll explore shrink tape for composites through the lens of three small-diameter products from the sporting goods industry: arrow shafts, golf clubs, and fishing rods.
It’s helpful to understand first how golf shafts, arrow shafts, and fishing rods are manufactured. They all follow a similar process that’s tailored to small diameters and overall performance requirements. A carbon fiber prepreg is cut to geometric patterns, then rolled over a mandrel or tool depending on design needs. Once wrapped, machines apply a layer of shrink tape or film to consolidate the layup. The assemblies are then hung vertically in ovens to cure, a process that enables uniform resin flow and surface quality. After curing, the tape or film is removed — sometimes peeled away like a snakeskin, other times stripped by high-speed unwrapping machines — before the shafts undergo sanding, painting, and labeling. With that clarified, let’s dig into the specific products.
When it comes to arrow shafts, consistency in compaction is quite possibly the most important outcome of the process. Whether for hunting, elite archery competitions, or even casual use, the consistent compaction of the resin and composite along the arrow shaft makes a difference — particularly when arrows receive frequent use.
Shafts where the compaction process was inconsistent can result in voids, delamination, weight imbalances, flexibility issues, and more. While some of these issues contribute to the accelerated breakdown of the shaft with each use, others will result in instant problems such as unpredictable aiming, inaccurate shots, arrow speed, and more.
Archery and golf are both high-precision sports, and the quality of the composite material and compaction processes will play a significant role in that precision. While compaction is critical with arrow shafts, it’s arguably more critical in golf club shafts because clubs will see dozens of swings (hopefully not hundreds!) during an average game. Any voids, imbalance in the resin flow, dry spots, and under-compaction could result in poor performance, weak feel, over/under-stiffness, and other negative outcomes.
With golf club shafts, precise layup tooling and processes are critical to success. Autoclaves are common here, but mandrels and shrink films are also a regularly used solution. With the latter, extreme precision is needed as the film is wrapped around the length of the part. It’s common to see high levels of over-wrapping and even multiple layers in order to achieve the compaction needed for consistency.
Fishing rods demand the same level of precision as composite arrow shafts and golf clubs — but for different reasons. In general, fishing rods don’t see the same high impacts as these other shaft types, but the stress on high-end rods can be intense — especially when there’s an aggressive, heavy fish fighting on the end of the line. However, proper compaction is still critical for success.
Voids in composite fishing rods actually reduce sensitivity to important moments, such as detecting micro-bites or vibrations. Poor compaction can also lead to dead spots along the shaft, creating higher risk of delamination, inconsistent bending and recovery, and lower energy transfer when casting.
While established manufacturers may already have autoclaves in place, they are not necessarily required in order to achieve the same level of compaction. Dunstone Hi-Shrink Tape is commonly used in high performance applications where consistent compaction throughout the curing process is essential to successful manufacturing.
The same levels of pressure achieved with an autoclave are also achievable with tape. Of course, this depends on the part geometry and circumference, but whether through machine winding or manual application, Dunstone Hi-Shrink Tape is an outstanding, reliable, and cost-effective solution.

There were a few specific improvements that are worth highlighting regarding enhancing composite consolidation: External compaction — Dunstone 220R Hi-Shrink Tape provided compaction pressure estimated at 0.6 bar, providing compaction for specimens that used it but not for non-autoclave specimens. The autoclave specimen had compaction at 4 bars. However, note that autoclave pressures are also possible using Dunstone Hi-Shrink Tape alone. Impact on consolidation — The use of Dunstone 220R Hi-Shrink Tape significantly reduced voids and delamination in the laminates, eliminating widespread defects with only localized defects remaining. Improved tensile strength — Specimens utilizing 220R Hi-Shrink Tape showed higher tensile strength compared to specimens without external compaction.

About Dunstone 220R Hi-Shrink Tape Dunstone 220 Hi-Shrink Tape is one of our most popular products and is well-known and used in the market — and across numerous industries. Our 200 Series, which includes 220R, has been referred to as the Swiss Army knife of shrink tape. There are several good reasons for this: Thinness — One of the thinnest offerings available, 220R measures just 0.002” (0.050 mm). This thinness equates to reduced material cost over other solutions because less is needed while still producing the desired consolidation and compaction. Pro tip: The first 2 in 220 refers to its thickness. Shrink percentage — The 200 Series provides a wide range of shrink percentage options depending on the application. In the instance of the above study, the 220R product offers 20% shrink — the highest of the 200 line. This equates to 8.6 foot-pounds of shrink force. Pro tip: The 20 in 220 specifies the shrink percentage. Release coatings — A release coating allows the tape to be easily removed from the layup, whereas normally you’d have to scrape it off or just leave it on depending on the application. Release coatings are available on one side of the tape or both. Additionally, our 220 Hi-Shrink Tape is available with a silicone release coating. Pro tip: Release coatings are specified after the number in the product name. 220R has a release coating on one side, 220RR is release coated on both sides, and 220S has no coating (S = standard). Customization — Dunstone 220R Hi-Shrink Tape is available in a variety of widths, lengths, core sizes, and more, and all of this can be customized for your application. Additionally, many of our Hi-Shrink Tapes can be modified with perforations for applications where outgassing is required.

Composites provide many advantages, including:
With these beneficial properties, it is no wonder composites can be found in a wide range of applications, including but not limited to:
Heat shrink tape can provide numerous benefits to your composite part manufacturing. Some of the biggest advantages of heat shrink tape during composite part manufacturing are:
Properly applying your tape is entirely dependent on the needs of your project. Before starting, it is important to evaluate your application, part design, cure temperature, and ideal shrink percentage for your composite parts.
Once you have evaluated the above, you can determine the right tape product for you. At Dunstone, we offer a wide range of Hi-Shrink taping solutions.
You can then experiment with the taping tension of your product. Depending on how tightly you wrap the tape, you can impact the amount of compression force on your product. While this is somewhat forgiving, it is important to experiment with what tension is right for your product. Check out our calculator to see what the right taping tension is for your application.
Once it comes to wrapping your product, it is important to make sure the tape is properly secured. Dunstone’s tape does not have adhesives on either side, so to secure the tape, start by using a piece of regular adhesive tape at the starting end or overwrap the tape. This can be done to secure the end of the part as well.

At Dunstone, we offer a wide range of Hi-Shrink taping solutions. 100 Series: This is our thinnest tape, applying a low to moderate shrink force, which makes it ideal for use on thin-walled composite parts 140 Series: This tape has a low to moderate shrink force and is suitable for composite tubes, ductwork, and more 200 Series: With its low to moderate shrink force, the 200 Series is often used to consolidate composite tubes and other thin-walled composite parts 300 Series: This tape is commonly used on thick-walled composites such as flexible ductwork, composite tubes, and more 500 Series: With its moderate to high shrink force, this tape is used for thicker-walled composite parts such as tubes, containment rings, and more HT Series: This tape is designed to provide release and moderate compaction forces that are durable in higher temperatures X Series: This tape has the ability to withstand significantly higher temperatures than other shrink tape on the market and has a maximum shrink force of 12% You can then experiment with the taping tension of your product. Depending on how tightly you wrap the tape, you can impact the amount of compression force on your product. While this is somewhat forgiving, it is important to experiment with what tension is right for your product. Check out our calculator to see what the right taping tension is for your application. Once it comes to wrapping your product, it is important to make sure the tape is properly secured. Dunstone’s tape does not have adhesives on either side, so to secure the tape, start by using a piece of regular adhesive tape at the starting end or overwrap the tape. This can be done to secure the end of the part as well.

From sporting goods to oil and gas to automotive, various applications require composites for their numerous benefits. However, there can be some defects in composites that impact the function and safety of an application. Let’s explore composites, their potential defects, and how to address them.
Composites provide many advantages to their applications. Some of the most common advantages of composites include:
There are a few common defects seen in composites for a variety of reasons, however, one of the most common causes of these defects is incorrect layup. Some common defects include:
Foreign object debris (FOD) in composites refers to the presence of unintended materials within the laminate. This is commonly caused by contamination during the layup process. Debris and foreign objects can negatively impact the mechanical properties and aesthetics of a composite, impacting its effectiveness of the application. This can contribute to dangerous failures for critical industries that require excellence and accuracy in their products.
These voids are empty spaces or gaps within the resin matrix where no resin or fibers are present. This essentially creates a hole in the composite resin. Voids can reduce the mechanical properties of the finished product, as well as negatively impacting the lifespan of the composite. Both mechanical properties and the lifespan are crucial to the critical applications of various industries, including aerospace, oil and gas, automotive, marine, and more, so avoiding voids is a necessity when creating composites.
Since many of the problems associated with composites can be attributed to improper layup, it is important to ensure you are enacting the proper techniques and using high-quality products and materials.
Finding and implementing a high-quality Hi-Shrink tape solution can increase the quality of your composites by decreasing the amount of defects. Hi-Shrink tapes remove voids in the resin and between layers of resin. Additionally, these tape solutions can improve the lamination of composites, give your products a high-quality surface finish and improve mechanical strength of your products all while increasing your output with minimal capital equipment cost.
Some Hi-Shrink tape solutions from Dunstone include:
The way you apply your Hi-Shrink tape can impact the performance of your composite. To properly apply your tape, you’ll need to understand your application and start experimenting with the tension and overlapping percentage that is right for your project. Both of these aspects of the application project can impact the compaction force of your Hi-Shrink tape.

Typically, three options are the most common: shrink tape, vacuum bagging, and autoclaving. Let’s explore shrink tape vs. vacuum bagging vs. autoclaving to help you determine which is the best solution for your particular project.
During the normal vacuum bagging process, the composite is laid up and resin infused as it’s put under vacuum to wet out and compact the laminate. This process has commonly been used to manufacture and repair composites. It removes air voids and produces parts with stronger properties, but the process does have some drawbacks.
It can be costly and time-consuming when multiple layers of composite materials are used. Vacuum bagging is also a complex process that requires extensive knowledge and high attention to detail, meaning only properly trained individuals can ensure that this process is done properly and safely. There are also some limitations on certain shapes and sizes, so this process cannot be used on irregularly shaped or complex structures.
An autoclave is a device that combines vacuum and external pressures to consolidate and laminate products. The vacuum portion removes air and volatiles while holding the resin in place as the external pressure suppresses any vapors into the resin matrix to prevent voids, which yields high-quality parts.
While autoclaving has many benefits, it does have some limitations. The process entails long cycle times and limited part throughput due to space in the autoclave that can be cost and part-output-prohibitive — particularly because autoclaves themselves can range dramatically in cost based on size, brand, and other factors, to the tune of several thousand dollars each. Additionally, autoclaving requires a great deal of energy to complete, further driving up the costs.
Using shrink tape to consolidate your resins and composites yields many benefits for your products. Not only does it improve the lamination of your products by removing voids in the resin and between the layers of resin, but it can also improve the mechanical strength of your cured parts. Shrink tape also gives your products high-quality surface finishes.
Shrink tape can also be customized to your application, as you have different options for shrink percentages and can obtain different results based on how your products are wrapped. There are three main factors that impact the results of your product:
At Dunstone, we offer various shrink tape solutions to meet the needs of nearly any project. Some of our solutions include:
However, shrink tape also has some disadvantages. You will need to precisely apply the shrink tape in order for it to function as expected. Additionally, it will take some time to get the overlap of the tape and the taping tension used, so you may lose time and some shrink tape product in the process.

Shrink Tape Using shrink tape to consolidate your resins and composites yields many benefits for your products. Not only does it improve the lamination of your products by removing voids in the resin and between the layers of resin, but it can also improve the mechanical strength of your cured parts. Shrink tape also gives your products high-quality surface finishes. Shrink tape can also be customized to your application, as you have different options for shrink percentages and can obtain different results based on how your products are wrapped. There are three main factors that impact the results of your product: Tape Thickness: The thicker the tape, the more pressure that is sustained pressure the underlying part will see during the cure. Even slight differences in thickness — and we’re talking thousandths of an inch here — is important to consider. Working with an expert will ensure you find the right tape for your application. Taping Tension: This is how tightly you wrap the shrink tape around your product and helps determine the overall force applied to your product. In order to determine the proper taping tension for your product, some experimentation may be needed, or check out our tension calculator here for helpful insight. Overlapping: The amount your tape overlaps can impact the compaction force of your shrink tape. Overlapping is measured in percentages, and the higher the percentage of overlap, the greater the compaction force. Typically, overlapping falls between 50% and 90%. At Dunstone, we offer various shrink tape solutions to meet the needs of nearly any project. Some of our solutions include: 100 Series: This is the thinnest Hi-shrink tape on the market and is recommended for use on products that do not require a significant shrink force. The 100 Series is available in shrink percentages from 5% to 20% depending on the needs of your application. 140 Series: This shrink tape solution offers low to moderate shrink force and is suitable for cure temperatures up to 165ºC, or 330ºF. The 140 Series is commonly used to consolidate electrical coils. 200 Series: Our 200 Series is our “Swiss Army knife”, with the ability to be used in a wide range of composite applications, including tubes, flexible ductwork, silicone hoses, and more. 300 Series: Our 300 Series is ideal for use on larger composite parts that require more compressive forces or have a more challenging resin system. This solution offers shrink forces of 5% to 20%. 500 Series: When you need a shrink tape solution for thick-walled composites that require moderate to high shrink force. Our 500 Series is commonly used to consolidate large composite tubes and containment rings. HT Series: This ETFE tape is very flexible, making it ideal for composites and resin systems that are complex shapes. Additionally, our HT Series has higher-temperature stability. X Series: Our X Series tape supports mechanical usage up to 400ºC cure cycles. This solution is often used in thermosetting resin systems and thermoplastic applications.

Construction and civil engineering projects need to have high-quality, durable materials that will function properly for decades. From composite poles and beams to building reinforcements and more, it is critical to ensure that your products and materials are properly consolidated and laminated so they are long-lasting and durable. One of the best ways to do this is by using Dunstone Hi-shrink tape.
These shrink wrap tape solutions make sure that composites and resin systems for the construction and civil engineering industries are properly compressed, resulting in parts that are stronger, longer lasting, and meet the high-performance demands of construction and civil engineering. In this blog, we will explore the applications, benefits, and solutions of utilizing construction shrink wrap tape in your projects.
As the shrink tape shrinks, compressive forces are applied to the underlying composites and resins. This eliminates voids in the product, giving it a smooth finish. While this also depends on the compression force you choose, the number of tape layers, and the taping tension used, this is still a huge benefit of construction shrink wrap.
With the right shrink force chosen, the number of tape layers, and the taping tension, your composites and resins will receive the exact amount of compression and lamination needed to be successful in their applications.
Depending on what your application needs, your construction shrink tape can be customized to meet all of your needs. This includes choosing the right shrink percentage and sizes needed to fit all of your applications. Plus, you can alter the shrink force by changing the way you wrap your composites. The more layers of tape you add will increase the compression force and the degree of wrapping tension will also increase or decrease the compression force.
There are quite a few applications of construction shrink wrap, all of which are critical to the safety and function of different parts of construction projects. Some of the common applications include composite poles, beams, and supports on bridges, building reinforcements, and being used as an aid to resist weathering, rust, and corrosion in outdoor applications.

The heat shrink tape is wrapped around your products and then heat is applied. This is usually done by using heat guns, an oven, or another heating source. As the temperature increases, the tape shrinks. This applies compressive force to the materials beneath, removing air pockets within the resin, pressing layers of material together to give a more consistent finish, eliminating gasses and other unwanted effects, or laminating them. Unlike nylon, cellophane, or woven materials, heat shrink tape does not relax during this process — meaning the consolidation of your products will not be impacted when heated.
At Dunstone, our Hi-Shrink heat shrink tape is adhesive-free, making application easy. Plus, when you are done laminating and consolidating your products, based on your application, the tape can be easily removed or grinded off without leaving residue — or it can be left on.
Heat shrink tape is often used in marine applications to ensure that composite and resin systems are properly compressed and that electrical components are safely insulated. Due to the harsh environment these applications are found in, they need to be extremely durable, and heat shrink tape can help make that possible.
In the automotive industry, heat shrink tape is used to compress composites and resins to make them stronger and last longer. These applications include carbon fiber drive shafts, composite tubes and rims, and carbon fiber rotor sleeves used in demanding EV motors.
Oil and gas tanks and pipes need to be kept secure and durable. Heat shrink tapes properly laminate and consolidate these applications to keep them safe and functional. Closely related to this is vulcanized rubber applications used for fluid transfer. Here, Hi-Shrink tape excels thanks to its compressive strength and ability to make the underlying material more resilient.
Hi-Shrink tape can be used to create long-lasting, strong, durable sporting goods. From golf club shafts and arrow shafts to rifle barrels to high-performance car drive shafts, and more, Hi-Shrink tape is used to improve the durability of a wide range of sporting goods.

First, you will need to start by understanding the needs of your application and finding the right tape for you. Once you’ve determined the right tape for your product, it’s time to start experimenting to find the right tension and overlapping percentage for your project.
The taping tension of Hi-Shrink polyester tape is how tightly you wrap the shrink tape around your product. The best way to determine this is through experimentation so you know exactly what tension works best for your product. If you want some additional information about how to determine tension, check out our calculator.
Overlapping will impact the compaction force of your Hi-Shrink tape. This is measured in percentages. The higher the percentage of overlap, the higher compaction force. These percentages usually fall between 25% and 75%.
When it comes to wrapping your product, it’s important to properly secure your Hi-Shrink tape. To do this, you can start the end of the tape with a regular adhesive tape or overwrap the tape around the starting end before proceeding laterally down the part. To learn more about the wrapping process, check out our video that walks you through the entire process.
At Dunstone, we manufacture various Hi-Shrink tape and tubing for a wide range of industries and products. We understand that our customers need their Hi-Shrink solution to function exactly as they need them to, which is why we offer custom converting solutions and shrink tape and tubing with different properties.

One of the most common types of gas stored in COPVs is hydrogen. Hydrogen gas is stored under pressure in order to increase storage density. This proves particularly useful in hydrogen powered cars — allowing the tanks to take up less space while holding the optimal amount of hydrogen gas.
There are various types of COPVs that are used for different applications, but most often they consist of an aluminum or steel inner layer and a composite wrapped outer layer. There are also options with a plastic lined layer. The composite overwrap is necessary for these vessels as the industries they serve become more demanding. The composite overwrap increases the burst strength. Let’s explore the types of COPVs and what composite tapes are best for them.
This type of COPV is made from either steel or aluminum. It is heavy and the least expensive type of composite overwrapped pressure vessel. Type 1 vessels are generally used in static applications, ground storage, small passenger cars, and industrial use.
Type 2 COPVs are mainly steel or aluminum but are designed to be lighter than Type 1. Due to its lighter weight nature, it is more expensive. These vessels are good for static applications, ground storage, and high-volume industrial use.
These vessels are aluminum with a composite wrap. They are lighter than Type 2 and can withstand higher pressures. Type 3 vessels are ideal for use in the industrial, transportation, aerospace, and military industries.
This type of vessel is made of a polymer, usually HDPE, with a composite wrap. It is the lightest option on the market, but much less robust than Type 3. It is used infrequently, such as in portable field testing and some military applications.
These vessels are made with composite liners. They have more usable volume and are lightweight. Type 5 vessels aren’t used very often, typically only in highly advanced military and aerospace applications.
Hybrid Composite Overwrapped Pressure Vessels combine the structural benefits of a metallic liner (like those in Type 3 vessels) with extensive composite wrapping (similar to Type 4 and Type 5 vessels). This hybrid construction results in a balance of durability and weight efficiency, making them ideal for high-performance applications where both durability and weight savings are crucial. Hybrid COPVs stand out by offering the reliability of a metal liner with the weight advantages of composite materials.
While different projects require different solutions, many COPV applications thrive when a heat shrink tape with a higher shrink percentage and force is used. These characteristics ensure that the composite overwrapped pressure vessel is functioning at its best and can endure higher pressures.
Dunstone’s 220R Shrink Tape is the ideal choice for use in most composite overwrapped pressure vessels. With a shrink percentage of 20% and a maximum shrink force of 8.59 foot-pounds, it can withstand these demanding applications while providing the necessary strength to consolidate the composite layers
One of the biggest advantages shrink tape brings is its ability to increase the strength of composites. There are a few things to consider when determining the best way to utilize shrink tape in your composite overwrapped pressure vessels:
Our team has decades of experience creating heat shrink tape for a wide range of applications. Our 220R Shrink Tape is a great starting place for COPV applications due to its high shrink percentage and force. Need a custom engineered solution, ask us how.

Type 1 This type of COPV is made from either steel or aluminum. It is heavy and the least expensive type of composite overwrapped pressure vessel. Type 1 vessels are generally used in static applications, ground storage, small passenger cars, and industrial use. Type 2 Type 2 COPVs are mainly steel or aluminum but are designed to be lighter than Type 1. Due to its lighter weight nature, it is more expensive. These vessels are good for static applications, ground storage, and high-volume industrial use. Type 3 These vessels are aluminum with a composite wrap. They are lighter than Type 2 and can withstand higher pressures. Type 3 vessels are ideal for use in the industrial, transportation, aerospace, and military industries. Type 4 This type of vessel is made of a polymer, usually HDPE, with a composite wrap. It is the lightest option on the market, but much less robust than Type 3. It is used infrequently, such as in portable field testing and some military applications. Type 5 These vessels are made with composite liners. They have more usable volume and are lightweight. Type 5 vessels aren’t used very often, typically only in highly advanced military and aerospace applications. Hybrid COPVs: Hybrid Composite Overwrapped Pressure Vessels combine the structural benefits of a metallic liner (like those in Type 3 vessels) with extensive composite wrapping (similar to Type 4 and Type 5 vessels). This hybrid construction results in a balance of durability and weight efficiency, making them ideal for high-performance applications where both durability and weight savings are crucial. Hybrid COPVs stand out by offering the reliability of a metal liner with the weight advantages of composite materials. The Best Composite Tape for COPVs While different projects require different solutions, many COPV applications thrive when a heat shrink tape with a higher shrink percentage and force is used. These characteristics ensure that the composite overwrapped pressure vessel is functioning at its best and can endure higher pressures. Dunstone’s 220R Shrink Tape is the ideal choice for use in most composite overwrapped pressure vessels. With a shrink percentage of 20% and a maximum shrink force of 8.59 foot-pounds, it can withstand these demanding applications while providing the necessary strength to consolidate the composite layers How to Use Shrink Tape in Your Composite Overwrapped Pressure Vessels One of the biggest advantages shrink tape brings is its ability to increase the strength of composites. There are a few things to consider when determining the best way to utilize shrink tape in your composite overwrapped pressure vessels: Taping Tension refers to how tightly you wrap your product in Hi-Shrink Tape. Tension varies based on the application of your product, with higher tension increasing the compressive force on the part. The compressive force continues to increase under the application of heat, so it is important to keep that in mind while determining the tension. Tape Thickness ranges from 0.001 inch (0.025 mm) to 0.005 inch (0.125 mm) at Dunstone. The thicker the tape, the more compressive force it applies as it shrinks. Number of Tape Layers will also determine how much compressive force is applied to the part. The more layers of tape you have, the more compressive force is applied. Overwrapping your heat shrink tape involves overlapping the tape during application. This impacts the performance of your product by increasing compressive force.

While it may seem like a small detail, heat shrink tape thickness is another crucial consideration to make when determining the right shrink tape for you. So, why exactly does heat shrink tape thickness matter?
Learn more about heat shrink tape by downloading our no-obligation ebook.
One of the primary reasons why heat shrink tape thickness is so important is its influence on the compaction strength of the tape. In fact, the thickness can be a determining factor in the compression strength of the heat shrink tape. The thicker the tape, the more compressive force is applied as it shrinks. Conversely, the thinner the tape, the less compressive force is applied as it shrinks.
For example, our 100 Series Hi-Shrink Tape has a thickness of 0.001” (0.025 mm) and a max shrink force 4.3 lbf. On the other hand, our 500 Series Hi-Shrink Tape has a thickness of 0.005” (0.125 mm) and a max shrink force of 21.6 lbf.
In addition to its impact on compaction strength, different heat shrink tape thicknesses may be better depending on the size of your composite. When choosing a heat shrink tape, you should also take into account the size and thickness of your composite. For example, a larger composite that is thicker may need a thicker heat shrink tape while a small-diameter composite may require a thinner tape. Some larger composites include oil and gas tubing, which will require thicker tape, such as our 500 Series Hi-Shrink Tape. Sporting goods applications, such as automotive drive shafts and golf club shafts, are significantly smaller and require a much thinner tape. This will improve the overall compression of your composite and may ease the wrapping process.
At Dunstone, we carry a wide range of our Hi-Shrink Tapes. We have numerous products with available thicknesses ranging from 0.001 inches (0.025 mm) to 0.005 inches (0.125 mm).
The 100 Series Hi-Shrink Tape is among the thinnest on the market. With a thickness of just 0.001 inches (0.025 mm), this polyester film is ideal for thin-walled composite parts that require a low to moderate shrink force. Despite its thinness, the 100 Series Hi-Shrink Tape is suitable for cure temperatures of up to 330ºF or 165ºC. This series is commonly used for consolidating flexible ductwork, silicone, and rubber hoses during curing and vulcanization.
Dunstone’s 140 Series Hi-Shrink Tape is just slightly thicker than the 100 Series with a thickness of 0.0014 inches (0.035 mm). The 140 Series is suitable for thin-walled composites and can handle cure temperatures up to 330ºF or 165ºC. Usually, this Hi-Shrink Tape is used for consolidating electrical coils.
The 200 Series polyester film has a thickness of 0.002 inches (0.050 mm) and is able to handle cure temperatures up to 330ºF or 165ºC. Since this composite is still relatively thin, it is ideal for use on thin-walled composites. Our 200 Series is typically used to consolidate composite tubes, flexible ductwork, and silicone hoses.
The 300 Series is a slightly thicker polyester film. With a thickness of 0.003 inches (0.075 mm), it is great for thicker-walled composites. Similar to the other tapes mentioned above, the 300 Series is suitable for cure temperatures up to 330ºF or 165ºC.
The 500 Series is a 0.005” (0.125 mm) thick polyester film that is ideal for use on thicker-walled composites and parts that require a high compressive force. Generally, this series is used to consolidate large composite tubes and containment rings.
The HT Series is a multilayer film, made with ETFE and Nylon. This film has a thickness of 0.002 inches (0.050 mm), is suitable for temperatures up to 356ºF or 180ºC, and is ideal for applications that require slightly higher temperatures and excellent release characteristics.
The X Series also has a thickness of 0.002 inches (0.050 mm), however, it is able to handle the highest temperature on the market. It supports mechanical use up to 752ºF or 400ºC. This tape is ideal for curing thermoplastics like PEEK and PPS.

Explore key variables that will impact part performance, costs, and more here.", "content": "Polyimide tape is used in a variety of applications ranging from oil & gas equipment and electrical insulation to automotive components and even aerospace systems. This is due to the fact that polyimide tape can withstand extremely high temperatures, has great chemical and electrical resistance, and even has solid mechanical compression properties. It’s the go-to solution for many composite manufacturers who have high cure temperatures both for thermoset and thermoplastic applications, but just as important as polyimide tape is to the application is the choice of polyimide tape supplier.
Identifying strong partners has been a challenge for many companies — and for some time. Whether you’ve been bouncing between suppliers or are just now beginning to suffer from your current polyimide tape supplier’s inability to meet your demand (or make important modifications to maximize application performance), the list below will help as you explore other options for polyimide shrink tape.
The supply chain issues of recent years are continuing to plague many polyimide tape suppliers, as well as manufacturers of shrink films beyond polyimide. Constantly looking for a steady source of supply doesn’t help you achieve your production goals. Work with a supplier that is able to meet your unique supply requirements. Learn more about the supply issues and how to evaluate whether a supplier can meet your needs.
Just as important as being able to meet demand levels is the ability of a polyimide tape supplier’s product to work effectively with your composite parts and resin systems. While polyimide off the shelf is useful, it needs to work properly as temperatures rise during curing cycles and as resin viscosity begins to drop — which is right when greater compression needs to occur. A modified polyimide tape that applies greater compressive force as temperatures rise will improve yield and ensure the reliable performance of the composite part post-cure.
While your application will benefit from a tailored shrink process, what also matters is getting a tape that is specifically designed for it. You might need greater thickness, a narrower or wider slit, a specific webbing, or a very specific shrink percentage. Perforations may also be needed to allow outgassing. Whatever the demands of your unique application may be, working with a polyimide tape supplier that can meet them will help control material costs, streamline production processes, and maximize part performance. Learn more about customizing shrink tape for your application.
Dunstone has been supplying industry-leading shrink tape solutions to companies in multiple industries for more than 50 years. Our line of Hi-Shrink Tapes are some of the thinnest materials available on the market today, yet they can be customized to meet the specific needs of virtually any application. We’ve engineered our Hi-Shrink Tape products to apply compressive force on a tailored curve based on curing temperature and other criteria — ensuring the best possible result while preventing waste.
While we have many Hi-Shrink Tape options in stock, including our 212HT high temperature shrink tape and 208X polyimide shrink tape, we are able to best serve your application by speaking with you and applying further customization if needed. We encourage you to request a sample of our tapes for testing, followed by a conversation with our engineering team to discuss how we can further maximize the performance of our tapes.

Dunstone Hi-Shrink Tapes are available in thicknesses ranging from 0.001 in. (0.025 mm) up to 0.005 in. (0.125 mm). Explore our various shrink tapes here.
The number of Hi-Shrink Tape layers used follows the same principle as above because more layers means a thicker overall layer of tape around the part. Greater compressive force will be applied to the part with more layers.
The higher the shrink percentage of the tape, the higher the shrink force applied to the part. Dunstone offers Hi-Shrink Tapes with shrink percentages ranging from 5% up to 20%. Explore our shrink tapes here.
Increasing taping tension increases the compressive force on the part. Applying the tape under tension will immediately begin to compact the part. When the tape begins to shrink under the application of heat, the compaction force applied to the part will increase further. Learn more about how to properly apply shrink tape in this video.
Inversely related to compaction force, the larger the diameter of the part being wrapped, the lower the compaction. Large diameters usually require thicker tapes and/or more layers of tape to achieve desired compaction. Contact us if you have questions regarding a large-diameter application.

We offer shrink percentages from 5–20% in most of our films. Shrink force, also called shrink tension, is the force exerted by the tape as it shrinks. It is measured in lbs/force per inch of width. Note that shrink percentage is not always related to shrink force — some products with a higher shrink percentage will exert little to no shrink force (and vice versa).
Individual applications vary greatly, so please contact us with the details of your application. You can also view the available tape options from our Hi-Shrink Tapes main page where they are sorted by film thickness and temperature class. Additionally, you can request a sample to evaluate in your production environment.
We offer either an ETFE or a polyimide shrink tape for high-temperature cures. Which one you will need will depend on the your cure temperature and how much compaction force you require. Please check out our Hi-Shrink Tapes page to select a tape based on temperature requirements.
Dunstone can solve a void problem with our Hi-Shrink Tape. Contact us to discuss the application, and we can send a sample for evaluation.
The shrink initiation temperature for our tapes is 65°C (150°F). Max shrink percentage and shrink force are typically achieved between 120–150°C (250–300°F).
No. Hi-Shrink Tapes are non-adhesive films and in most applications are intended to be removed from the part after cure.
Hi-Shrink Tape is applied by spiral wrapping the tape over the outer surface of the part. The starting end of the tape can be secured with an initial wrap over itself, or by using a small piece of adhesive tape to hold it in place. Continue to wrap the tape in a spiral manner around the circumference of the part, moving lengthwise down the part with each successive wrap. Be sure to wrap each subsequent layer of tape on itself with the same degree of overlap (see Figure 1 below). If you’re not sure how much overlap to use, start with 50% and then determine after part cure if you need more or less compaction force. If more force is required, increase your overlap percentage. Decrease overlap if less force is required. Watch our video on how to use heat shrink tape here.

Most users are applying between 5 and 8 lbs. of force when taping. No matter what your taping tension is, it is important to try and maintain consistent and even tension during the taping process. Variations in taping tension can lead to variations in compaction force, the end result being visual defects on the part surface and possibly porosity issues within the composite layers themselves. There are 2 methods for applying the tape: by hand, or with automated taping equipment. When taping by hand, a good rule of thumb is to keep the tape “snug” against the part surface, avoiding any loose wraps of film. This should give you a clean, consistent part surface after the tape is removed. When taping with automated equipment, it is much easier to maintain consistent and specific target tension numbers, as the equipment is doing it for you. Refer to the variables affecting compressive force page or contact us if you have further questions about taping tension or making adjustments to improve part quality.
Probably not. It is very common to see resin bleed out between the layers of tape. The cured resin on the tape outer surface should not interfere with the removal of the tape. The perforated tape is normally used when the curing resin system is out-gassing volatiles or water vapor, and it helps those gasses escape from the surface of the part. Learn more about perforations here.

You can also view the available tape options from our Hi-Shrink Tapes main page where they are sorted by film thickness and temperature class. Additionally, you can request a sample to evaluate in your production environment. Do you have a tape that can be used for high-temperature cure cycles common with thermoplastic resin systems? We offer either an ETFE or a polyimide shrink tape for high-temperature cures. Which one you will need will depend on the your cure temperature and how much compaction force you require. Please check out our Hi-Shrink Tapes page to select a tape based on temperature requirements. I use a non-shrink tape and still have voids in my composite wall. Can your Hi-Shrink Tape help? Dunstone can solve a void problem with our Hi-Shrink Tape. Contact us to discuss the application, and we can send a sample for evaluation. At what temperature does Hi-Shrink Tape start to shrink? The shrink initiation temperature for our tapes is 65°C (150°F). Max shrink percentage and shrink force are typically achieved between 120–150°C (250–300°F). Does Hi-Shrink Tape have adhesive on one side? No. Hi-Shrink Tapes are non-adhesive films and in most applications are intended to be removed from the part after cure. How do you apply Hi-Shrink Tape to the part? Hi-Shrink Tape is applied by spiral wrapping the tape over the outer surface of the part. The starting end of the tape can be secured with an initial wrap over itself, or by using a small piece of adhesive tape to hold it in place. Continue to wrap the tape in a spiral manner around the circumference of the part, moving lengthwise down the part with each successive wrap.

I’m using a wet-wind process or have a very resin-rich prepreg. Do I need to use a perforated Hi-Shrink Tape to squeeze out extra resin? Probably not. It is very common to see resin bleed out between the layers of tape. The cured resin on the tape outer surface should not interfere with the removal of the tape. The perforated tape is normally used when the curing resin system is out-gassing volatiles or water vapor, and it helps those gasses escape from the surface of the part.

What do the letters in your Hi-Shrink Tape product numbers represent? Letters in our product names indicate that the product has certain features or properties. Below is a helpful key: Release Coatings R — release coated on the outside of the tape I — release coated on the inside of the tape D / RR — release coated on both sides of the tape Si — the release coating is Silicon Perforations P — the product comes with perforations (learn more) B — the product has perforations and a release coating on the outside Other S — indicates a standard product (no coatings, perforations, etc.) HT — indicates our high temperature product, 212HT X — indicates our ultra high temperature polyimide tape, X Series How do I read your product numbers? Our Hi-Shrink Tape features an easy-to-understand naming convention that reflects the properties of the tape as well as any key features. Using 220R Hi-Shrink Tape as an example: [2][20][R] [2] — represents the thickness of the tape measured in thousandths of an inch (in this case, 0.002” or 0.050 mm) [20] — represents the shrink percentage (%) of the tape (in this case, 20% shrink) [R] — identifies a release coating or special type of film (in this case, 220R has a release coating applied) What is the shelf life of Hi-Shrink Tape and Tubing? There is no definite shelf life on Dunstone Hi-Shrink Tapes and Hi-Shrink Tubing. Dunstone products will remain usable for many years if stored properly. What is the best way to store Hi-Shrink Tape and Tubing? Store Dunstone Hi-Shrink Tape and Hi-Shrink Tubing in a cool, dry environment.

Designed with a much higher shrink percentage — up to 70% — to conform around various components, our PET shrink tubing can serve as a protective barrier or wear barrier for rigid materials as well as provide dielectric protection and address various needs in the medical industry. Our PET Hi-Shrink Tubing products are thin-walled with only a linear seam, enabling sizing flexibility and rapid shrink capabilities with just a heat gun or oven.
Learn more about our FEP Hi-Shrink Tubing below. Connect with our engineering team to discuss your application, or request a sample to evaluate in your production environment.
Dunstone FEP Hi-Shrink Tubing was custom-developed for tooling applications in which the outer tool surface must be covered with a release film prior to composite part lay-up. Typically, large, uniform cross-sectional tools are taped by hand — a painstaking process that takes significant time and can lead to production quality challenges. With Dunstone FEP Hi-Shrink Tubing and Sleeves, you can reduce tool prep and part lay-up time by sleeving the tool — providing the release layer needed while cutting work and costs. Applying heat initiates the shrink process, resulting in a tight, uniform covering on the tool surface.

Dunstone’s Hi-Shrink Tape is a heat-shrinkable tape that applies compression to an underlying structure when heat is applied, typically in a curing process. This powerful force can consolidate or laminate multiple layers of material beneath it, and the compressive force it delivers does not relax throughout the curing process, unlike other commonly used non-shrinking films. Cellophane, nylon, and polypropylene can relax and lose tension when used to overwrap composite parts during curing, resulting in less optimal lamination and material waste. Dunstone’s heat shrink wrap tape applies optimum compression throughout the process and empowers you to produce void-free composite parts with tighter lamination.
Hi-Shrink Tape is suitable for a wide range of applications and may be the ideal material to consider using for your next project depending on your unique needs and production environment. Read on to explore our expert breakdown of the product and how to find the right supplier for your heat shrink wrap tape.

Our guide to Hi-Shrink Tape is packed with product details, application recommendations, and more.
Download HereHeat shrink wrap tape is commonly made from materials like polyester or polyimide, both of which are temperature-sensitive and suit applications with composite and resin materials. When heated, heat shrink wrap tape compresses underlying components to aid in the lamination or curing process. Because Dunstone’s Hi-Shrink Tape is entirely adhesive-free, once lamination is achieved, the tape can be easily removed with no residue left behind.
Hi-Shrink Tape can empower your project with improved lamination, higher mechanical strength of the composite, and less foreign object debris and voids in your resin. For best results, it’s important to choose the right Hi-Shrink tape for your application needs, be consistent with the force you’re applying to your composite, and properly secure the tape.

", "content_plain": "About High Temperature Polyimide Tape When your consolidation application requires a high temperature solution, there’s no better answer than polyimide tape. Whereas many other shrink tapes peak at temperatures in the mid- to upper-300ºF (160–180ºC) ranges, high temperature polyimide tape is capable of providing strong shrink force at higher ranges: Electrical applications — up to 428ºF (220ºC) Mechanical applications — up to 752ºF (400ºC) Regardless of application, shrink begins at 158ºF (70ºC) Why Temperature Matters with Polyimide Shrink Tape This broad range for curing temperatures makes high temperature polyimide tape extremely flexible depending on your application, which is important for a couple of reasons that will impact part appearance and performance: Shrink Percentage — There are a number of other factors that influence shrink performance overall, but temperature is a leading contributor. If you want to control the maximum shrink percentage to your composite part, temperature must be a consideration. Lower curing temperatures will keep the shrink percentage around 8%, whereas higher curing temperatures will result in a higher percentage around 12%. Shrink Force — Another consideration is the amount of shrink force applied to the composite part. Shrink force is measured in ft-pounds per inch width. With higher curing temperatures, the shrink force of polyimide tape increases — up to 8.9 lb. in the case of our X Series polyimide tape. By focusing on the curing temperature of your part, you’ll be able to customize shrink force and maximum shrink to best suit your application. At Dunstone, we offer a variety of shrink tape solutions with varying levels of force to best meet your application requirements. Additional Reasons to Consider Using High Temperature Polyimide Tape in Your Application Thickness — At only .002” in thickness, our X Series Hi-Shrink Polyimide Tape is one of the thinnest high temperature materials available on the market. While .002” falls right in line with our other “Swiss Army knife” tapes, it still remains one of thinnest options — allowing you to achieve the performance and results you want without having to buy more material. Functionality — While our high temperature polyimide tape is designed to provide compaction, the tape itself can serve other distinct purposes. For example, it can be used as a mechanical compressive layer as well as dielectric insulation for electrical applications. So whether you’re using it to compress a very high tolerance part or if you’re working with electrical coils, polyimide tape will work for you. Adjustability — At Dunstone, we offer in-stock solutions but specialize in customizing your high temperature polyimide tape to your unique application. If you need a certain size, or if you need to modify the shrink percentage, our team is ready to work with you to create the most ideal shrink tape solution for you.

These two aspects make the greatest difference in how heat shrink tape works, but other details can influence the overall compressive force and end performance of the tape and the resulting product. These include:
It’s important to understand that heat shrink tape — particularly Hi-Shrink Tape engineered and manufactured by Dunstone — is not an adhesive-backed tape. In virtually every instance, the adhesive is not needed thanks to the natural properties of the tape and its ability to be easily applied to a composite part before curing. Additionally, if an adhesive were to be used, it could adversely affect the resin/composite matrix at the chemical level. You can learn more about how to use heat shrink tape here to improve application performance.
Hi-Shrink Tape is also meant to be a processing aid and is not meant to be used for the life of the part. While there are some applications in which our tape remains on parts (electrical coils are one such example), most applications will require the tape to be removed — either via manual removal such as scraping and grinding or via an optional release coating that is available on many of our shrink tape products. The latter allows the tape to be easily removed after curing without leaving any residue behind. These coatings are available on one or two sides depending on the application.

It’s no secret that organizations today are having trouble relying on past relationships when it comes to heat shrinkable tape suppliers. With materials continuing to be less available, yet demand for goods — ones that deliver lasting quality and performance — growing despite recession fears, material management and procurement leaders need more reliable sources of supply without the extra cost or sacrificing quality.
If your organization has been struggling to find heat shrinkable tape suppliers, or a current partner hasn’t been able to live up to service expectations, it’s crucial to evaluate your options sooner rather than later. Continuing to work with a partner that can’t meet your needs will lead to long-term negative outcomes, such as the inability to keep up with demand, inventory shortages, the need to lean on more expensive suppliers, placing more costly short-term orders for materials to bridge gaps, and more.
Here, we’ll explore a few key characteristics to consider when evaluating heat shrinkable tape suppliers — ones that will not only ensure that you have a reliable material partner but also one that can support your distinct production needs.
Depending on your product line, you might need heat shrinkable tape suppliers that specialize in one solution type or many. What’s important to consider here is that the partner is able to adapt to new needs. Whether you have one product or thousands, will they be able to pull from a portfolio of shrink tape solutions to help you keep production moving? Will they be able to quickly supply a solution for a new product or a change in the design or performance of an existing product?
Does your partner focus on offering off-the-shelf solutions, or are they a custom shop? Can they do both? More importantly, are they going to work with you to find the ideal heat shrinkable tape? An off-the-shelf solution might deliver some measure of performance, but will it maximize it? The right partner will deliver tailored shrink tape that meets parameters such as high-temperature performance, optimal shrink force and shrink percentage, and other needs.
Today more than ever, certain material manufacturers are having a difficult time either managing their own supply or keeping up with demand. Woven nylon tape (also called sail cloth or wrap tape) is one notable example. While this material has its uses, if it’s not available when you need it, you need to find alternative solutions. Polyester, ETFE, and polyimide heat shrink tapes are more readily available solutions that provide greater compaction, ease of use, application speed, and even cost-effectiveness.
Every product is different and requires the right production materials to make it a success. For example, some composite parts use raw materials and resin systems that produce gasses and vapors. These must be allowed to escape the composite layup during the curing process. In this instance, a perforated shrink tape would be needed (contrary to popular belief, these perforations aren’t for allowing excess resin to escape — just outgassing).
Another example is a composite product that requires an extremely high curing temperature. To ensure success, and so the tape doesn’t fail, a polyimide tape would be needed. This material can withstand temperatures three times higher than standard shrink tapes and is useful for a variety of other purposes, such as electrical insulation.
A final consideration — and one that’s becoming increasingly important in today’s tight labor market — is automation. Heat shrink tapes are often hand-wrapped around a part, which requires precision to ensure a consistent outcome. However, some shrink tapes can be produced on laterally wound cores, allowing them to be used with traverse winding mechanisms and eliminating the need for hand-wrapping.
With decades of experience in helping companies across a variety of markets find the right shrink tape for their needs, Dunstone is the heat shrinkable tape supplier you’ve been looking for. We source all materials from domestic suppliers, and we offer a broad portfolio of products along with the capabilities, technical expertise, and resiliency you need to keep up with demand and deliver consistent results.

Simply reach out, let us know some details about your application, and we’ll be happy to provide you with a complimentary sample of our readily available shrink tape. If the tape works well for your application (and we’re confident it will), you can place a larger order or discuss further customizing the tape with our expert engineers.
While a struggling supply chain continues to plague manufacturers across multiple industries, it’s not the only issue causing frustration and delays. Your partners and consumers demand more out of their products, which means the components used to make them need to deliver specific and reliable performance designed for the application. Working with a compression film supplier that can take your shrink materials to the next level is critical for success.
Depending on your application, an off-the-shelf shrink tape or shrink tube solution might meet your needs. But can you take that performance further? Would a shrink solution designed for extremely high temperatures help? Would a customized solution that delivers higher compression on a tailored curve result in a more consistent surface finish? These are important considerations for improving not only your end product but also streamlining your production efforts overall.
Here, we’ll quickly explore a few key details that you should look for when researching a compression film supplier to understand if they’re the right partner for your needs.
Your compression film supplier should be a partner that you work with to make your overall operations better, and a key to that is providing a variety of product and material types to enhance your production. An off-the-shelf product won’t be a catch-all for every product in your portfolio or every challenge you come across. Work with a compression film supplier that can meet your needs with the right product at the right time.
Many compression films actually begin to relax or experience other negative effects as curing temperatures rise. This can result in reduced part or surface finish quality and other defects. Working with a compression film that increases compression as temperatures increase eliminates the risk of the film loosening right when resins begin to drop in viscosity. The result is a more consistent surface finish that’s free from voids and debris as well as a better performing product. Additionally, depending on the application, the right film — such as a shrink tape — can be left on the part rather than having to scrape it off post-cure.
This one is extremely important. Your part and process are unique, and that means you need a unique solution to maximize positive outcomes. While many shrink tapes and shrink tubes can produce consistent results across a variety of applications, you may be able to make significant improvements by working with a compression film supplier that can customize their material options. Material thickness, length, compression force, max curing temperature, and more can all be modified to ensure you get the results you’re looking for.
As a result of all of the supply chain and labor issues over the past couple of years, many manufacturers are looking for ways to automate their production efforts — whether through the use of robots, cobots, or simply more efficient production processes. Shrink tapes and shrink tubing play an important role in this. For example, working with a compression film supplier that can provide shrink tape on a laterally wound core enables you to use winding equipment to wrap a part. This is faster than wrapping by hand and produces more consistent results.
Last but not least, choose a compression film supplier that has experience in multiple industries. Their experience across different markets means they’ll have experience with the countless ways that shrink tapes and shrink tubing are used on parts as well as different companies’ production processes. The result is a more well rounded understanding of how shrink materials can be best applied and used to achieve specific goals, which benefits you in the long run. They may be able to recommend a better material for your goals and be able to advise you on ways to maximize its performance based on how you’ll be using it in your production environment.

Go custom — and never look back: Learn how Dunstone can support your unique application with a fully customized solution.
While Dunstone offers a variety of readily available Hi-Shrink Tape solutions, our niche is developing and providing customized heat shrink tape for unique situations to ensure our clients are able to become more efficient in their production — while also saving on material costs where possible. Below are two recent scenarios where our customizable heat shrink tape helped to streamline processes and automate compression on key parts.
Go deeper: The production challenges of today have led many companies to reconsider the tools they’re using for part production. Learn why it’s always a good time to revisit your shrink tape and tubing solutions.
With decades of experience in shrink tape and tubing applications, Dunstone has developed a full portfolio of solutions designed to maximize compaction results during the curing cycle. While many of our Hi-Shrink Tapes come in standard roll lengths of 100 yards, we are fully capable of producing rollings of significantly greater length — even longer than the 4,000-meter roll mentioned above.
If your application requires a long length of continuous tape (applying tape laterally along the length of a composite part), we can supply our tapes on wider rolls in which the tape is over-wrapped along the length of the core. Simply feed the tape into an appropriate winding mechanism and enjoy a consistent application along the length of your composite part.
For instances where hand-taping is preferred or more beneficial, we can provide flat-packs (think a standard roll of tape where the material is fully wrapped around itself) for use by production teams. Whereas winding mechanisms will produce a consistent application, hand-taping can be more inconsistent. Ensure your team understands how to apply the tape with the recommendations outlined here.
The best first step is connecting with our team to discuss your application and goals. If we have a solution ready to go from our product inventory, we’ll be happy to send a complimentary sample to you for testing in your environment.

The current economic environment has led to a variety of supply chain and production changes for multiple industries. This is no different for manufacturers of composite products that serve critical functions in multiple downstream markets such as energy, oil and gas, automotive, aerospace, sporting goods, and more. One key challenge for composite manufacturers has been finding the right heat shrink tape to fit their new compaction requirements.
This particular material challenge comes hot on the heels of composite manufacturers struggling to find suitable alternatives solutions to already solved problems. Additionally, manufacturers that have implemented new resin systems are finding them incompatible with their previous compaction solution. This is if such resin systems are even available, as material shortages — including composite fibers themselves — have impacted manufacturers worldwide.
As a result of all of this change, companies are beginning to explore new solutions for maintaining and improving performance during the curing cycle. Whether your current shrink tape solution is no longer available, it’s no longer compatible with a new resin system you’re working with, or you’re experiencing quality issues as a result of change (e.g. delamination, porosity, inconsistent surface finish, or voids) or maybe you have other concerns with your existing resin system such as labor intensive compaction solutions. It may be time to explore your options for a resin heat shrink tape alternative.
A common cause of these physical problems is the presence of gas and other volatiles that are unable to escape during curing. Additionally, many non-shrink films and tapes don’t provide the tailored compaction needed as curing temperatures rise. Thus, gasses and volatiles aren’t compressed, forced through the matrix, and allowed to out-gas (escape).
Solutions:
Delamination and inconsistent surface finishes typically result from incorrect application of a heat shrink tape or insufficient compaction. Improperly wound tape that doesn’t have the right (and consistent) amount of overlap and surface tension won’t apply the same amount of compressive force during cure. The same will affect the resulting surface finish.
Solutions
Whether you’re experiencing the issues above with your resin heat shrink tape or are moving forward in your production without issue, now is always a good time to ensure you have the best possible shrink tape solution available. Often, companies are able to reduce costs with thinner or even less compaction tapes while still benefiting from the same or greater amount of compressive force. It all depends on the material and who you’re working with.
At Dunstone, we work closely with each client to understand their unique application, their intended performance outcomes, and their supply chain goals. In virtually all cases, we’re able to recommend a Hi-shrink tape that provides more consistent compaction while also reducing costs. Many of our tapes can be traverse-wound as well, enabling greater automation during a time when skilled labor is difficult to find.
The best first step is connecting with our sales and engineering team to discuss your application. If we have a shrink tape solution for you, we can provide a sample so you can safely test it in your production environment to see if it melds well with your process and materials. We are also able to customize our tapes for more specific performance needs.

Why You Might Be Experiencing Issues Voids and Porosity A common cause of these physical problems is the presence of gas and other volatiles that are unable to escape during curing. Additionally, many non-shrink films and tapes don’t provide the tailored compaction needed as curing temperatures rise. Thus, gasses and volatiles aren’t compressed, forced through the matrix, and allowed to out-gas (escape). Solutions: The first step is using a Hi-shrink tape that applies compressive force as the temperature rises. Cellophane, nylon, and other materials require tight wrapping tension up front in order to apply compression, but they can weaken during cure. At Dunstone, our Hi-Shrink Tapes are custom-tailored to apply greater force as the temperature increases — right as resins begin to drop in viscosity. This ensures that consistent compression is applied to the part and prevents voids from forming. Another key solution is using perforated tape. Often, people mistakenly believe perforations are for allowing resin to escape, but the reality is that material can escape between the layers of tape. The perforations actually allow gasses to escape as more and more compression is applied. Combined with a proper heat shrink tape, perforations ensure that your composite parts are free of voids and porosity. Delamination and Surface Finish Problems Delamination and inconsistent surface finishes typically result from incorrect application of a heat shrink tape or insufficient compaction. Improperly wound tape that doesn’t have the right (and consistent) amount of overlap and surface tension won’t apply the same amount of compressive force during cure. The same will affect the resulting surface finish. Solutions Learning how to properly wrap Hi-Shrink Tape will go a long way in ensuring each application is consistent and achieves the desired results. While some experimentation is needed (particularly for newer products, resins, and fibers) to find the right tension, overlap, etc., experimenting until you find the right results will ensure the best possible outcome. Ask us about the variables affecting compressive force on a part. Similar to issues with voids and porosity, it’s critical that you use a resin shrink tape that will apply consistent compressive force. A variety of Hi-Shrink Tapes are available based on your application and the amount of force needed. Discussing your application with an engineer will help you find the right option. Even If You’re Not Having Issues, It’s Likely That Improvements are Still Possible Whether you’re experiencing the issues above with your resin heat shrink tape or are moving forward in your production without issue, now is always a good time to ensure you have the best possible shrink tape solution available. Often, companies are able to reduce costs with thinner or even less compaction tapes while still benefiting from the same or greater amount of compressive force. It all depends on the material and who you’re working with. At Dunstone, we work closely with each client to understand their unique application, their intended performance outcomes, and their supply chain goals. In virtually all cases, we’re able to recommend a Hi-shrink tape that provides more consistent compaction while also reducing costs. Many of our tapes can be traverse-wound as well, enabling greater automation during a time when skilled labor is difficult to find. The best first step is connecting with our sales and engineering team to discuss your application. If we have a shrink tape solution for you, we can provide a sample so you can safely test it in your production environment to see if it melds well with your process and materials. We are also able to customize our tapes for more specific performance needs.

To ensure composite products deliver reliable and consistent performance, an oil and gas heat shrink tape is required.
We’ll explore the advantages of oil and gas heat shrink tape shortly, but first it’s important to understand why composite products are important to this industry. Composites can be found across a variety of applications in oil and gas today, ranging from fluid transfer pipes and tanks to deepwater and ultra-deepwater offshore drilling and exploration equipment.
Advantages of carbon fiber and other composite products for oil and gas include:
In order for a composite part to achieve these properties, it must be properly compressed during a curing cycle, when heat is applied to multiple layers of material and resin. This process eliminates unwanted elements such as gas, voids, and other foreign object debris (FOD) while consolidating layers and creating a consistent surface finish.
While there are a variety of heat shrink film solutions available, not all provide consistent compaction as curing temperatures increase. For example, some materials must be tightly wrapped before the curing process and relax as temperatures increase and resin begins to drop in viscosity. This is the exact moment when greater and sustained compaction is needed. To solve this challenge, we developed our line of Hi-Shrink Tapes that apply compressive force on a tailored curve, increasing the pressure as temperatures rise.
Whereas our 100 and 200 Series of Hi-Shrink Tapes are some of the thinnest available on the market, our 500 Series Hi-Shrink Tapes are much thicker at .005” (0.0125 mm). This increased thickness results in much higher compressive force and maximum diameter shrink (which can be customized to your unique application). It’s designed for curing temperatures up to 330°F (165°C) and is ideal for thicker-walled composite parts such as large-diameter composite tubing. As with many of our other Hi-Shrink Tapes, the 500 Series is available non-coated, release coated on one side, or release coated on two sides.
Depending on your application, you may have complex or uneven components made of composite materials that also need appropriate compaction. And as with other composite components, higher curing temperatures may be required to consolidate the composite layers. Dunstone designed the HT Series of Hi-Shrink Tapes for these types of applications. Made of two layers of ethylene tetrafluoroethylene (EFTE) sandwiching a nylon layer, the HT Series provides reliable compaction for temperatures up to 356ºF (180ºC). It has strong natural release characteristics and is non-coated yet leaves no trace transfer.
We understand that every application is unique and demands equally unique production support. Our Hi-Shrink Tapes and Hi-Shrink Tubing can be custom-tailored according to the demands of your application and the environment in which they’ll be used. Another key benefit of our shrink tape is that it can and is often used in the field to make repairs to existing pipes — adding another use case beyond upfront production.
We put decades of engineering and manufacturing expertise to work in each project to ensure that the tape or tubing provided delivers reliable performance and results, which in turn results in stronger products. Our Hi-Shrink Tapes and Tubing are much more cost-effective than other materials due to their thinness. And, our tapes and tubing can be provided in custom sizes and lengths, allowing you to get the exact material that works best for your production process. Our team is also available to advise you on how to best apply our products to your composite parts to maximize performance.

Composites can be found across a variety of applications in oil and gas today, ranging from fluid transfer pipes and tanks to deepwater and ultra-deepwater offshore drilling and exploration equipment. Advantages of carbon fiber and other composite products for oil and gas include: Corrosion Resistance — They allow for prolonged usage and longevity in corrosive environments such as salt water and where harsh chemicals are used. This is an environmental benefit in that leaks due to corrosion are reduced. High Strength — Carbon fiber and other composite components have a much higher tensile strength than steel (in some cases up to seven times higher), allowing them to perform more reliably when exposed to various forms of pressure. High Durability — Because of its strength and corrosion resistance, carbon fiber has a longer lifespan than steel products and can stand up to harsh weather, high temperatures, weather, aging, and rough use. Lightweight — Carbon fiber is vastly less dense than metals such as steel and aluminum, making it ideal when weight reduction is a goal for a part or process. In order for a composite part to achieve these properties, it must be properly compressed during a curing cycle, when heat is applied to multiple layers of material and resin.

Simply reach out to us to discuss your application, and our engineering team will prepare a solution with the right shrink percentage, length, and thickness needed.
High Shrink — Our PVC heat shrink sleeve products shrink up to 70% in diameter, which allows for a tighter fit around the underlying part or material. This allows for greater conformity around the part, creating a more aesthetic look while also reducing the amount of space between the shrunk tubing and part in sharper or more geometric areas.
Ease of Use — While production teams can use curing ovens to initiate the shrink process, our PVC heat shrink sleeve tubing can also be rapidly shrunk using just a heat gun. This means your production team can process more parts faster, increasing overall productivity and reducing the time needed to properly sleeve products.
Size Flexibility — Our Hi-Shrink Tubing is thin-walled and linear-seamed to allow for flexibility in sizing. Tubing is produced according to the application and shrink percentage, typically from .002” to .010”. Custom sizing is available starting at 64 mm layflat. Learn more about layflat tubing here.
Customization — Our PVC shrink tubing can be produced on spools of continuous lengths greater than 2,000 feet. This means you can more easily sleeve products according to their length without having to deal with seams — simply cut the length needed and get shrinking!
Affordability — Unlike other solutions, our PVC shrink tubing is extremely affordable. This allows you to get the ideal performance and protection needed for your product while keeping your investment in materials lower.

Electrical heat shrink tapes are essential to that outcome. Examples of products requiring this kind of shrink tape include high voltage (HV) coils, resin-rich coils, DC field poles, pre-consolidated coils, wiring systems, and other products requiring a sacrifice film, compression, or dielectric insulation.
Whatever the need, Hi-Shrink Tape from Dunstone is one of the leading solutions for companies looking to achieve excellence in the performance and longevity of their manufacturing processes.
Non-shrink films like cellophane, woven nylon, and polypropylene have to be wrapped at high tension and in multiple layers in order for the material to provide the necessary compaction. The problem is that these materials relax as the curing temperature rises — right when the resin begins to drop in viscosity and flow. The results are less than ideal.
That’s why Dunstone developed our Hi-Shrink Tape products. These tapes begin shrinking at 70ºC / 158ºF and apply compressive force as the temperature rises along a tailored curve. The result is a more even compression process that eliminates foreign object debris (FOD), air voids, and a resin-rich surface finish. Additionally, because Hi-Shrink Tape gets the job done the first time and with less material, costs associated with this part of the production process are reduced.

The 140 Series of electrical heat shrink tape was designed for applications in the high voltage coil industry because it provides the right amount of tensile strength while remaining cost effective. As part of our complete 100 Series, the 140 line is only 0.0014” (0.0035mm) thick — making it one of our thinnest Hi-Shrink Tapes. Its shrink percentage can be adjusted based on the application (though it’s ideal for thin-walled composite parts) and is available with a single- or double-sided release coating for instances when the tape needs to be removed from the part after the curing process is finished.
Learn more about our 140 Series Hi-Shrink Tape.
The 200 Series Hi-Shrink Tapes are our most common shrink tape, working perfectly for a wide variety of applications — electrical and otherwise. Specifically, the 220R line has been used in electrical applications that include power generation. In one example, an OEM wanted to use our Hi-Shrink Tape to prevent fatigue and wear of end-windings on HV coils. Not only did 220R provide maximum consolidation of the insulation materials being used but it also worked well in the sharp coil radii where it can be challenging to properly consolidate layers. The 220R line is only 0.002” (0.050mm) thick, and just like the 140 Series is available with a 1- or 2-sided release coating — allowing the resulting surface finish to be free from defects and eliminating the need to grind the tape off.
Learn more about our 200 Series Hi-Shrink Tape.
Our X Series tape was designed for applications where the usage temperature is much higher (up to 200ºC / 392ºF for electrical usage and even higher for mechanical usage) and in which the curing temperature is higher than other shrink tapes can handle. A modified polyimide material, our X Series Hi-Shrink Tape begins to shrink at 70ºC / 158ºF but will reach its maximum shrink percentage at 350ºC / 662ºF. It is most often used to consolidate HV coils and is typically not removed from the part. Like our 200 Series, it is only 0.002” (0.050mm) thick, providing the compressive force needed in a single material while providing additional dielectric and mechanical properties as well.
Learn more about our X Series Hi-Shrink Tape.
Last but not least is our 500 Series of Hi-Shrink Tapes. This line of products is our thickest at 0.005” (0.125mm) and also provides the highest amount of shrink force of our entire Hi-Shrink Tape product line at 21.64 pounds of force at 150ºC / 302ºF. Because of this immense pressure that it can exert on a part, it is most often used for consolidating rubber hoses, flexible ductwork, and silicone hoses, but it does have utility in electrical applications such as HV coils. Like some of the products mentioned here, it’s available with a 1- or 2-sided release coating or without a release coating based on your application.

While PET tubing can be used for a variety of production purposes, it’s important to use a truly customized solution to achieve the results you’re looking for. Just like other shrink tape and tubing materials, PET is extremely customizable to increase its performance in durability, temperature resistance, electrical insulation, and shrink abilities. Here, we’ll provide a quick checklist to help you understand what goes into getting the right custom PET tubing for your goals. Still considering your options? Take a quick run-through of seven benefits of PET shrink tubing. What to Consider for the Best Custom PET Tubing Product Application — First and foremost, it’ll be important to understand how your custom PET shrink tubing will be used. Are you sleeving a component that needs dielectric protection to prevent current from passing through? Do you need a sleeve for extreme wear resistance to protect the component underneath? Will your application see a great deal of chemical exposure? Understanding your application is the first step toward determining if a custom PET tubing product is right for you. Shrink Percentage — In order to take advantage of the benefits mentioned here, PET tubing must fit your component tightly. Any gaps could result in unwanted materials or debris getting under the sleeving, or an electrical current getting out. Thus, PET tubing typically features an extremely high shrink percentage upward of 70%. This is to ensure that the material not only provides the necessary compression but that it also fits the unique contours of your component while delivering the required performance. Shrink Temperature — Depending on your application and production volume, you might not need to use autoclaves or ovens (such as when sleeving high-performance composites like carbon fiber in which a variety of factors like resin system and FOD elimination must be addressed). PET begins to shrink at a much lower temperature, typically around 60ºC (140ºF). This means you can get the shrink performance you need using only a heat gun operated by a team member, making the process faster than using curing equipment. Component Design — Depending on the design of your component or product, you might need more or less custom PET tubing to get the job done. You might also need a thinner tubing wall depending on how the component will be used and how much shrink is needed. On the length side, custom PET tubing is available on spools of continuous lengths up to 2,000 feet, saving production teams time and effort in having to seam together shorter lengths. PET can also be produced with extremely thin walls, saving you money on the product overall while still delivering results. PET tubing is linear-seamed in production, making it even more flexible to work for your needs.

The polymer can be refined by customizing the selection and amount of diamines and dianhydrides (those interested can go in-depth into the science of polyimides here).
A common application that requires the use of polyimide tape is high-temperature electrical insulation, such as with the consolidation of high voltage coils in power generators. Other applications can be found with advanced composites used in automotive, energy, and aerospace markets, such as in curing thermoplastics such as PEEK and PPS resin systems.

At Dunstone, we offer this high-temperature, dielectric tape in the form of our X Series Hi-Shrink Tapes, specifically the 208X line. Unlike other tapes that feature a maximum shrink temperature of 160ºC (320ºF) to 180ºC (356ºF), our 208X line of Hi-Shrink Tapes still begins its tailored compression curve at 70ºC (158ºF) but can continue shrinking and applying compressive force all the way up to 400ºC (752ºF).
An important note: The application in which 208X is being used will determine the appropriate maximum temperature. If you’ll be using it to apply compressive force to parts for electrical purposes, the maximum temperature is 220ºC (428ºF). For mechanical applications, the maximum temperature is the aforementioned 400ºC (752ºF).

If you’re manufacturing products in one of these industries, you’re likely using a compaction film of some kind to compress composite materials such as carbon fiber, Kevlar®, or fiberglass, or you might need to apply light compression to vulcanized materials such as rubber, silicone, or PVC for hose, roller or fluid transfer purposes.
While there are a variety of compaction film options available, only Hi-Shrink Tape from Dunstone provides the consistent, reliable compaction needed to produce the desired results while also keeping costs down and increasing overall productivity. This is because it provides compression on a tailored curve as the curing temperature increases, whereas non-shrink films like cellophane, woven nylon, or polypropylene will begin to relax with higher temperatures — putting system integrity at risk and leading to low-quality products with poor performance.
But with a variety of tapes available, what’s the best heat shrink tape for your specific needs? Do you need a solution that functions in extremely high curing temperatures? Perhaps a Hi-Shrink Tape that’s incredibly thin with a lower shrink percentage is ideal. Or, you might need a shrink tape that provides a much higher compressive force to ensure the resin system properly penetrates the layers and spaces in the material.
Here, we’ll explore a few questions to ask in order to understand what the best heat shrink tape is for your respective application. Of course, there may be additional considerations that aren’t explored here. It’s always best to speak with one of our expert engineers regarding your use case and end goals. Connect with them now to get started.
Our guide to Hi-Shrink Tape is packed with product details, application recommendations, and more.
Download HereAs you explore our portfolio of Hi-Shrink Tapes, you’ll see that there are a wide range of shrink percentage and force figures for different products. The term MD shrink refers to the shrink percentage in the machine direction. Tapes are available with MD shrink percentages ranging from 5% up to 20%. Max shrink force, just as it sounds, refers to the amount of force applied in pounds per inch of width. Our tapes apply anywhere from 1.65 (HT Series) lb. of force up to nearly 22 lb. of force (500 Series).
It’s important to understand that a number of other factors contribute to the overall compressive force being applied to a part. Other elements like tape thickness, taping tension, the number of layers of tape used, overwrapping percentage, and the diameter of the product being wrapped all contribute to the result. If you or your production team are fairly new to this product type, check out our blog on how to use heat shrink tape.
Calculate PSI during tape application: Use our handy calculator to determine how much pressure is being applied by using a specific tape based on your usage details.
As mentioned above, tape thickness is a key consideration in identifying the best heat shrink tape. It’s extremely fast and easy to identify the thickness of Dunstone Hi-Shrink Tapes — the first number in the numerical name of a product (e.g. 210S) refers to the thickness in mils. So 210S is 0.002 inches thick, or 0.05 in millimeters. We offer our Hi-Shrink Tapes in 1-, 2-, 3-, and 5-mil thicknesses, with 2-mil tapes being the most common and accessible.
But what thickness is right for your application? Generally, if you have a thin-walled part that’s smaller, you’d use a thinner Hi-Shrink Tape (like the carbon fiber shaft of a golf club). Larger, thicker products, like drive shafts or composite utility poles would require a thicker tape in order to provide the required compressive force. Of course, every application is different, so be sure to discuss yours with our team.
Unlike adhesive-lined tapes, Dunstone Hi-Shrink Tapes don’t require any adhesive in order to be fixed to a part. They can simply be wrapped around and fixed by overlapping the starting end. In most cases, the tapes are simply removed from the part after curing or ground off. In some instances, the tape stays in place — serving as a protective barrier. That said, some resins or materials may require an additional solution for removing the tape. This is where release coatings come into play.
Dunstone offers our Hi-Shrink Tapes with one- or two-sided release coatings. These are indicated in our product part names by an S (standard, no coating) or an R (release coated). After the curing process, a release-coated Hi-Shrink Tape can quickly and easily be removed from the layup, typically without leaving behind any “cello marks” and producing a consistent, clean surface finish. We also have a new release coating available in the 200 Series line that is a zero-transfer UV-cured Silicone coating that can used for demanding release applications where the standard PTFE coating will not work. Contact us for details.
All of our 100, 200, 300, and 500 Series Hi-Shrink Tapes come in standard or release-coated variations. Our HT series is naturally designed to provide excellent release characteristics, and the extremely high-temperature X series also provides some release abilities.
A final — and very important — consideration for your application is what the best heat shrink tape is for resin systems and materials that, when compressed, either produce or could trap various gasses and other volatiles in the matrix. Failing to allow these elements to escape can also result in voids, imperfections, or de-lam (when the layers don’t properly bond). In these instances, a perforated shrink tape is critical to success.
However, many people mistake these perforations as a method for allowing the excess resin to escape the layup during compression. While this can technically happen, most excess resin actually escapes between the tape layers. The perforations are intended for gasses and other volatiles to pass through — resulting in more consistent part appearance and performance while reducing the chance of voids and other negative results post-cure. Two specific Dunstone Hi-Shrink Tapes with perforations include our 220R and 220S series.

", "content_plain": "Heat shrink tape is a critical component in the production environments of multiple industries around the world — ranging from automotive, aerospace, and energy to sporting goods, oil & gas, and many other industrial manufacturing applications. If you’re manufacturing products in one of these industries, you’re likely using a compaction film of some kind to compress composite materials such as carbon fiber, Kevlar®, or fiberglass, or you might need to apply light compression to vulcanized materials such as rubber, silicone, or PVC for hose, roller or fluid transfer purposes. While there are a variety of compaction film options available, only Hi-Shrink Tape from Dunstone provides the consistent, reliable compaction needed to produce the desired results while also keeping costs down and increasing overall productivity. This is because it provides compression on a tailored curve as the curing temperature increases, whereas non-shrink films like cellophane, woven nylon, or polypropylene will begin to relax with higher temperatures — putting system integrity at risk and leading to low-quality products with poor performance. But with a variety of tapes available, what’s the best heat shrink tape for your specific needs? Do you need a solution that functions in extremely high curing temperatures? Perhaps a Hi-Shrink Tape that’s incredibly thin with a lower shrink percentage is ideal. Or, you might need a shrink tape that provides a much higher compressive force to ensure the resin system properly penetrates the layers and spaces in the material. Here, we’ll explore a few questions to ask in order to understand what the best heat shrink tape is for your respective application. Of course, there may be additional considerations that aren’t explored here. It’s always best to speak with one of our expert engineers regarding your use case and end goals. Connect with them now to get started. Download our Complete Guide to Hi-Shrink Tape Our guide to Hi-Shrink Tape is packed with product details, application recommendations, and more. Download Here How Much Shrink Force is Needed? As you explore our portfolio of Hi-Shrink Tapes, you’ll see that there are a wide range of shrink percentage and force figures for different products. The term MD shrink refers to the shrink percentage in the machine direction. Tapes are available with MD shrink percentages ranging from 5% up to 20%. Max shrink force, just as it sounds, refers to the amount of force applied in pounds per inch of width. Our tapes apply anywhere from 1.65 (HT Series) lb. of force up to nearly 22 lb. of force (500 Series). It’s important to understand that a number of other factors contribute to the overall compressive force being applied to a part. Other elements like tape thickness, taping tension, the number of layers of tape used, overwrapping percentage, and the diameter of the product being wrapped all contribute to the result. If you or your production team are fairly new to this product type, check out our blog on how to use heat shrink tape. Calculate PSI during tape application: Use our handy calculator to determine how much pressure is being applied by using a specific tape based on your usage details. How Thick Does the Tape Need to Be? As mentioned above, tape thickness is a key consideration in identifying the best heat shrink tape. It’s extremely fast and easy to identify the thickness of Dunstone Hi-Shrink Tapes — the first number in the numerical name of a product (e.g. 210S) refers to the thickness in mils. So 210S is 0.002 inches thick, or 0.05 in millimeters. We offer our Hi-Shrink Tapes in 1-, 2-, 3-, and 5-mil thicknesses, with 2-mil tapes being the most common and accessible. But what thickness is right for your application? Generally, if you have a thin-walled part that’s smaller, you’d use a thinner Hi-Shrink Tape (like the carbon fiber shaft of a golf club). Larger, thicker products, like drive shafts or composite utility poles would require a thicker tape in order to provide the required compressive force. Of course, every application is different, so be sure to discuss yours with our team. Is a Release Coating Required? Unlike adhesive-lined tapes, Dunstone Hi-Shrink Tapes don’t require any adhesive in order to be fixed to a part. They can simply be wrapped around and fixed by overlapping the starting end. In most cases, the tapes are simply removed from the part after curing or ground off. In some instances, the tape stays in place — serving as a protective barrier. That said, some resins or materials may require an additional solution for removing the tape. This is where release coatings come into play. Dunstone offers our Hi-Shrink Tapes with one- or two-sided release coatings. These are indicated in our product part names by an S (standard, no coating) or an R (release coated). After the curing process, a release-coated Hi-Shrink Tape can quickly and easily be removed from the layup, typically without leaving behind any “cello marks” and producing a consistent, clean surface finish. We also have a new release coating available in the 200 Series line that is a zero-transfer UV-cured Silicone coating that can used for demanding release applications where the standard PTFE coating will not work. Contact us for details. All of our 100, 200, 300, and 500 Series Hi-Shrink Tapes come in standard or release-coated variations. Our HT series is naturally designed to provide excellent release characteristics, and the extremely high-temperature X series also provides some release abilities. Does the Application Produce Gas or Other Volatiles? A final — and very important — consideration for your application is what the best heat shrink tape is for resin systems and materials that, when compressed, either produce or could trap various gasses and other volatiles in the matrix. Failing to allow these elements to escape can also result in voids, imperfections, or de-lam (when the layers don’t properly bond). In these instances, a perforated shrink tape is critical to success. However, many people mistake these perforations as a method for allowing the excess resin to escape the layup during compression. While this can technically happen, most excess resin actually escapes between the tape layers. The perforations are intended for gasses and other volatiles to pass through — resulting in more consistent part appearance and performance while reducing the chance of voids and other negative results post-cure. Two specific Dunstone Hi-Shrink Tapes with perforations include our 220R and 220S series. Go deeper: Learn more about the value of perforated shrink tape here.

Thousands of the products that individuals use every day and businesses use in downstream manufacturing processes are made from carbon fiber. But to achieve the desired properties, a shrink tape for carbon fiber prepregs and layups is needed.
Unfortunately, many companies today still use non-shrink films like woven nylon, polypropylene, and cellophane. While these materials do provide compaction, they lose that compressive force as the cure temperature increases. As a result, the compression curve decreases — reducing the integrity of the process right when resin viscosity begins to decrease. Had a shrink tape been used, compression would continue and hold throughout the curing temperature — even up to extreme temperatures like 400ºC (752ºF).

Download HereDunstone began working with a sporting goods company that manufactured small-diameter arrow shafts made from carbon fiber. Previously, the company used a carbon fiber prepreg wrapped in a non-shrink film for compaction during the curing process. The challenge in this instance was that the non-shrink film was leading to a large number of shafts with inconsistent straightness — a key factor in whether a product was put in a lower-grade category versus a higher-grade category.
With the goal of increasing the number of higher-grade shafts produced, they turned to Dunstone for a solution for shrink tape for carbon fiber shafts. We recommended a compaction tape solution that saved the company from having to invest in more non-shrink material while still receiving a high-compaction solution. The tape allowed for a higher taping tension while also providing additional consolidation during the curing process. It also made the application process faster, helping the company save on labor time. This resulted in greater mechanical stiffness and an increased percentage of higher-grade shafts being produced in each batch.

Drive shafts are an essential part of a vehicle’s control system as they transfer power from the motor to the wheels. Historically, composite drive shafts were more often seen in high-end racing or aftermarket upgrades. Today, they are being more consistently implemented in many manufacturers’ cars, with integration in SUVs, compact cars, and other vehicle types continuing to increase thanks to their higher level of performance.
Dunstone partnered with a drive shaft manufacturer to provide a compaction solution for their products. Because the part was very long and consistent compaction was needed, we recommended our 220R Hi-Shrink Tape product, which the company applied with a steep overlap to maximize the compression along the part. This ensured that the strength of the carbon fiber was captured in combination with the resin system being used.

Whereas shrink tape products are designed to wrap around a composite part before the curing process (and even remain wrapped around that part depending on the application), FEP layflat tubing is designed to shrink around different types of tooling — such as mandrels, inflatable bladders, and SMART tooling — to serve as a release layer, meaning it’s intended to enable the quick and easy part removal post-cure.
The term “layflat tubing” refers to how the size of the tubing is determined. Essentially, the width of the outside diameter of the tubing when it is laying flat on a surface can be doubled to identify the maximum circumference or perimeter of the tubing when applied around parts.

Here, we’ll explore several reasons why Hi-Shrink FEP tubing from Dunstone is the ideal choice when compared to other release layer solutions. Thinnest Material Available — The greatest advantage of our Hi-Shrink FEP layflat tubing is that it’s the thinnest shrink tubing currently available. The immediate advantage here is that thinner material equates to less material, thereby creating cost savings and improving profitability on part production. Our FEP shrink tubing can be produced as thin as .04445 mm — vastly thinner than competitors’ standard of .10 mm. Improved Bladder Performance — Closely related to the above is the fact that thinner FEP tubing results in reduced inflatable bladder distortion. This is due to lower shrink force and lower shrink percentage (around 10%, give or take 2% — diameter only; the tubing will not shrink in length). Despite this, our FEP tubing shrinks up to 66% faster than competing tubing, saving even more time in labor and tooling preparation. Faster Sleeving — Using other release layer solutions such as shrink tape or non-shrink film could require time-consuming hand application followed by an equally extensive removal process. Additionally, non-shrink films won’t conform to mandrel and bladder surfaces as well since they do not shrink with heat. With FEP layflat tubing, sleeving is a much faster process, and the shrink process can be initiated quickly with just a heat gun. Prevents FOD — Foreign object debris is a common problem when workers are hand-taping tooling and can lead to poor part performance, damage, and other unwanted effects. With FEP layflat tubing, tooling is sleeved with a consistent material without the risk of contaminants finding their way onto the tool or composite part surface. Reduces Mark-Off — Ensuring a clean, consistent surface finish is critical, but with taped-on release liners or other adhesive products, the results can be anything but. Because FEP shrink tubing only has a small seam down its length, the impact on the surface finish is drastically reduced or eliminated altogether. Simply sleeve the part with the seam on a corner or angle, and it will be drastically less visible. Extensive Size Options — Every application is unique. To support your success, Dunstone can provide our Hi-Shrink FEP tubing in a variety of layflat sizes (anywhere from 64mm up to 500mm) as well as custom spool lengths (up to 1,000 feet of continuous length). This ensures that you’re able to order a sufficient amount of material in the dimensions you need for a lower cost than other solutions and remain productive. Custom Solutions — In addition to standard FEP shrink tubing, Dunstone is fully capable of developing custom solutions as needed. Our shrink tubing is also now available as custom-made, non-shrink preforms. We are always open to customizing our proven products to take their performance even further. Simply let us know what your application entails, and we’ll develop a solution to maximize your success.

Advantages of PET Shrink Tubes Extremely High Shrink — Designed to shrink significantly so it properly sleeves your products, PET shrink tubing has the highest shrink level of our entire tubing portfolio. It features a shrink percentage of up to 70% — more than double our next highest shrink tubing, PVC, which caps out at around 35%. Lower Shrink Temperature — Shrink initiates quickly and easily at a rapidly achievable 60ºC (140ºF) temperature. This means PET shrink tubing can quickly begin to shrink with just a heat gun or oven, making the production process more efficient, while also protecting the products being sleeved from higher temperatures. Rapid Shrink — Thanks to the lower shrink temperature, our PET shrink tubes also shrink incredibly quickly. This allows production workers and processes to move more smoothly, sleeving more products and shortening overall manufacturing time. Linear Seamed — Our PET shrink tubes are linear seamed along the length of the tube, which provides flexibility in sizing. This ensures that whether you need a shorter length or a fairly long piece of tubing for your application, you’ll only have a minor seam that is visible after the shrinking process has been completed. Customization — Along with our other shrink tube products, our PET shrink tubes can be customized to your exact application and what performance outcomes you want to achieve. We can also support your supply needs, such as providing PET shrink tubes on spools of continuous lengths up to 2,000 feet. Simply connect with our team to discuss your application, and we’ll work on a solution. Dielectric Protection — If your application involves products containing electrical current that must be prevented from traveling to other materials, PET shrink tubes are a great solution. Their dielectric properties mean they don’t allow current to flow. This protects other materials that might come into contact with the product. Wear Resistance — Depending on your product, you may need a solution to cover it throughout its lifespan. Thanks to the sheer flexibility of PET shrink tubes, this material is the ideal choice for getting the right size and protective properties needed.

In many production environments, this tape is hand-wrapped as opposed to being applied by an automated process (though that is common as well). Whether the tape is hand-wrapped or applied via equipment depends on your products and goals, but the ideal outcome should be easily attainable as long as certain factors are observed during the process. Today, we’ll review several of these and how our Hi-Shrink Tape line of products excels in applications where hand-wrapping is required.
Not all compaction films provide the amount of shrink needed to achieve success with a given material. Basic films like cellophane, nylon, or polypropylene are often wrapped under high tension before being put into a curing process. Unfortunately, these films will relax as the temperature increases — resulting in a lower-quality lamination. With Hi-Shrink Tape, you choose a shrink percentage from the start. We offer hand-wrapped heat shrinkable tape products with shrink percentages ranging from 0% to 20%. The higher the shrink percentage used, the greater the compressive force on the part.
Pro Tip: Our Hi-Shrink Tapes are numbered according to their thickness and shrink percentage. In our 220 Series, for example, the first digit (2) represents the thickness in thousandths of an inch. The second two digits (20) represent the shrink percentage.
The thickness of your hand-wrapped heat shrinkable tape also plays an important part in how much compressive force is applied to the material. Tapes with greater thicknesses will apply more force to the wrapped material as the curing temperature increases. Dunstone offers Hi-Shrink Tapes with thicknesses that include 0.001” (0.025 mm), 0.002” (0.050 mm), 0.003” (0.075 mm), and 0.005” (0.125 mm) — with a few unique options available.

Along with your choice of material, one of the most important factors in the performance of a hand-wrapped heat shrinkable tape is how much taping tension is applied when wrapping the part. This combined with the shrink percentage of the tape influences the amount of overall force (in pounds per inch of width) applied to the product. On average, most people using hand-taping composite materials are applying between five and eight pounds of force, but it’s essential that hand-wrapping is consistent from end to end.
Failing to maintain consistent taping tension when applying the tape will result in an uneven surface finish and even porosity in the composite layers themselves. This puts the overall product performance at risk. When hand-wrapping heat shrinkable tape, it’s important to keep the tape snug to the part surface and ensure there are no loose areas in the application. Get more tips on hand-taping in our FAQ section here.
Closely related to the above is the number of layers or overlap used when hand-wrapping the tape. While the number of layers will depend on your part and what you’re looking to achieve, multiple layers will provide greater compaction. Additionally, the amount of overlap will produce greater compaction as well. It’s important to be consistent with the amount of overlap as the tape is wound around the circumference of the part and down its length. It’s also critical to wrap each subsequent layer using the same overlap percentage.
With Dunstone Hi-Shrink Tape, a common approach is to test the compaction beginning with a 50% overlap. If more force is needed, the overlap can be increased to 75%. For less force, 25% overlap will ease up on the compaction applied to the part.
We’ve Got Answers: Check out our FAQ page to see common questions about tape application.
Whereas smaller diameter parts will see easy compaction thanks to our hand-wrapped heat shrinkable tape products, those with larger diameters will generally require thicker tapes, higher overlap percentages, higher tension, and perhaps more layers of tape in order to achieve the desired compressive force. To support applications with these larger parts, we developed our 500 Series of Hi-Shrink Tapes. This product provides maximum compressive force thanks to its .005” thickness. As with our other Hi-Shrink Tapes, we can customize the amount of shrink percentage needed for your application.
While hand-taping is required in many applications, consider whether your environment could benefit from the implementation of a traverse pack of shrink tape. These packs are traverse-wound on a core that is wider than the slit width, allowing for longer continuous lengths of shrink tape. The key advantages here are:

One good example is rubber rollers, which are used in paper and steel mills, carpet manufacturing, and many other applications. To ensure high-quality results, the rubber used on the rollers must be vulcanized — a process in which the rubber is heated and mixed with sulfur to help its molecules form stronger, more resilient cross-links. This process also helps ensure that the rollers will perform well despite being a wear item, meaning that they need to be replaced.
Traditionally, a variety of low-shrink compaction films have been used when curing rubber components. These include cotton strapping, nylon wrap tape, and polypropylene. However, in some of the industries mentioned above, higher curing temperatures or greater compaction force are needed to ensure the rubber roller or other component will deliver the desired performance in its respective application. In these instances, a rubber vulcanizing tape is necessary.
Dunstone is a leading developer and supplier of a full portfolio of Hi-Shrink Tape products designed for exactly this purpose. In particular, our 100 and 200 lines of rubber vulcanizing tape serve the applications mentioned here extremely well and come in both standard and release-coated versions.

Here, we’ll explore a few key advantages that our Hi-Shrink Tapes provide when you’re looking to cure rubber rollers, tubes, covers, and related products.
Steam plays a part in many rubber curing applications due to its high temperature. If your application involves steam — particularly with an autoclave — but you need to apply compaction, our Hi-Shrink Tapes are the ideal solution. Unlike other compaction films, our tapes are designed to apply compressive force on a tailored curve that maintains an appropriate amount of compaction as the curing temperature increases. Other films cannot withstand the high temperatures or the use of steam, leading to failures and/or unwanted results such as poor lamination, voids, and surface defects.
Learn more about the advantages of high-temperature shrink tape.
A key advantage of Dunstone’s Hi-Shrink Tapes is that far less material is required when compared to other compaction films and tapes. This is because our rubber vulcanizing tapes are specifically formulated to apply greater compaction force while only measuring anywhere from 0.001 inches (for the 100 Series) to 0.002 inches (for the 200 Series). As a result, fewer layers are needed, the tape can be overlapped for even more compressive force, and widths and lengths are customizable to ensure you have all the material you need for your respective application. With other films, you might need a significant amount to receive the same level of compaction.

Learn more here.", "content": "These include carbon fiber, Kevlar, and even thermoplastics such as polyphenylene sulfide (PPS) and polyetheretherketone (PEEK). In many of these applications, extreme curing temperatures are needed to produce the performance qualities needed: high tensile strength, chemical resistance, weight-to-strength ratios, and other advantages related to the use of composites. A high-temperature heat shrink tape is the ideal solution for ensuring these properties are achieved.
The Hi-Shrink Tape is wrapped around the composite prior to being placed in an oven or being heated with a heat gun. This is done by hand or, in some applications, via a traverse winding mechanism that applies the tape laterally. As the temperature rises, the tape begins to shrink — applying force to the layers of composite material and resin between them. This force is necessary for a variety of reasons:
But when the application calls for higher-than-normal curing temperatures, standard compaction films and shrink tapes won’t be able to apply their tailored compression beyond a certain temperature — resulting in the tape and the curing process itself failing. In these instances, a high-temperature heat shrink tape is needed. Dunstone proudly offers two high-temperature heat shrink tapes to support these specific applications.
Our 212HT line of high-temperature heat shrink tape is a multi-layered ethylene tetrafluoroethylene (ETFE)-based film with a Nylon middle layer that is ideal for applications with temperatures up to 180ºC or 356ºF. At only 2 mils thick (0.002 in or 0.050mm), it is far thinner than competing solutions — meaning you use less overall material. It has a maximum shrink of 12%, applying 1.65 pounds of compressive force. In applications where components are being hand-taped, 212HT can be applied with up to 10 pounds of taping tension.
In addition to working well in high-temperature curing applications, 212HT is also extremely flexible. It features 300% elongation, allowing it to be used on a variety of parts with complex or uneven surfaces. As a naturally releasing fluoropolymer film, 212HT does not require a coating in order to provide outstanding release characteristics and won’t leave any trace residue on parts. It is available on 1.5” or 3” internal diameter (ID) cores and in standard widths from 0.5” up to 2.5” to ensure you have the right coverage for your application.

Our most popular high-temperature heat shrink tape is our 208X series — the highest-temperature Hi-Shrink Tape available that’s capable of providing compressive force in curing cycles with temperatures up to 400ºC or 752ºF. It is made of a modified polyimide and begins to shrink at approximately 70°C (158ºF), reaching maximum compressive strength at 350ºC (662ºF). 208X is often used in electrical coil consolidation to provide a smooth surface finish but is also used for dielectric insulation alongside its mechanical compressive properties.
This high-temperature heat shrink tape features a maximum shrink of 14%. Shrinking begins at 70ºC, reaching 8% shrink at 225ºC and the full 14% near 400ºC. In mechanical usage instances, the tape can be used up to the full 400ºC temperature. In electrical applications, users should limit temperatures to 220ºC (428ºF). As part of the greater 200 Series of Hi-Shrink Tapes, 208X is also only 2 mils thick, is non-release coated but can serve as a release layer, and can withstand far greater taping tension than the 212 HT line — up to 50 lbs. This particular tape is highly customizable as well, allowing our team to create a solution specific to your needs.

Depending on your application, you may be in need of an adhesive heat shrink tape for applying compressive force to your composite parts and products. Whether you’re looking to produce pipes and hoses for fluid or gas transfer, components for vehicles or aircraft, or any other number of solutions calling for compressive force to ensure product quality, it’s clear that a heatable compaction film or tape is needed to create the desired results.
But when it comes to achieving the quality and other material properties you want in your composite products, the last thing you need is an adhesive heat shrink tape. Adhesives can leave residue or other traces on your products after the curing process. Additionally, the adhesive itself may fail as the temperature rises, causing the tape to fail or creating negative effects due to chemical reactions between the tape and the resin.
Fortunately, you don’t need an adhesive heat shrink tape to ensure a consistent, resin-rich surface finish that’s free from voids, foreign object debris (FOD), and other unwanted elements. At Dunstone, we offer a complete line of Hi-Shrink Tape products in a variety of thicknesses, widths, and interior diameters (IDs) and with a wide range of curing temperatures, shrink percentages, and other valuable traits — all without any adhesives or residues.
Here, we’ll cover some of the key advantages that our Hi-Shrink Tapes provide. If you’d like to talk with one of our application experts about your part needs, simply reach out to us here. We’ll be happy to help.
First and foremost, how is it that our Hi-Shrink Tapes work without the need for adhesive? It all starts with the materials the tapes themselves are made from. At Dunstone, we use polyester (Mylar), ethylene tetrafluoroethylene (ETFE), and polyimide. These materials feature natural release characteristics, allowing them to be removed from a part after the curing process — if the tape is meant to be removed at all. In cases where the tape serves as an insulative layer, it can simply remain on the product after curing. We also offer many of our tapes with release coatings on one or two sides depending on the application. These coatings ensure the tape is cleanly removed from the part, leaving behind a smooth finish. Application is easy. The tape can be secured to the part initially by winding a few wraps of the tape tightly over itself. Continue spiral wrapping the tape down the length of the part, and then secure the final end of the tape with a few wraps of an adhesive tape, like masking or flash breaker tape.
Depending on the application, you might have a need for a high-temperature shrink film. This is common with thermoplastic resin systems where curing temperatures can be anywhere from 180ºC (356ºF) up to 400ºC (752ºF). To support these production needs, Dunstone offers two high-temperature heat shrink tapes in our 212 HT and 208X lines. A multilayered shrink tape, our 212HT line addresses the lower end of this temperature range while also providing exceptional flexibility for parts with complex shapes and angles. The 208X is the highest-temperature shrink tape available on the market, serving applications requiring cure temperatures well into the 300ºC range and above. Many adhesive heat shrink tape options would have failed well before these temperatures, yet Dunstone Hi-Shrink Tape continues to provide compaction on the same tailored curve as our other Hi-Shrink Tapes.
In some applications, various volatiles and gases must be permitted to escape the wet layup. If they weren’t able to out-gas (escape) during the curing cycle, they could create air pockets, voids, de-lam, and other unwanted effects on the surface or deeper down in the laminate layers — causing product quality and appearance issues. To solve for this, Dunstone offers many of our Hi-Shrink Tapes in perforated variations. These perforations consist of tiny punched holes on quarter-inch staggered centers along the length of the tape. This allows the vapors and gasses to escape the layup, resulting in a stronger product and resin-rich surface. Learn more about perforated tape, what it’s meant to do, and what it’s not meant to do here.
While we offer many Hi-Shrink Tape solutions that can serve as a ready replacement for adhesive heat shrink tape, not every application can rely on the same products. Different materials, resin systems, and product performance and appearance goals mean you might need a completely customized solution. To help you achieve the right outcome, Dunstone proudly offers customization services on our Hi-Shrink Tapes. Our team will happily review any existing materials and processes you’ve been using and will then develop a solution to solve your respective challenge. With decades of experience, our engineers will not only provide a shrink tape that will work for your application but one that will also meet your respective budget requirements.

In these industries, the end products being manufactured need to have a specific shape, surface finish, and overall high level of performance in order to withstand the often harsh conditions to which they’re exposed. This is achieved through the use of tooling such as mandrels, inflatable bladders, and SMART Tooling™ — formable, reusable tooling solutions for parts with complex geometries.
Tooling serves as the ‘mold’ for a composite matrix layup or prepreg — a combination of multiple layers of a reinforcement matrixl like carbon fiber or Kevlar™ along with a specific resin system. Together, these materials are heated and compressed during a curing cycle to form the finished product — an extremely resilient, strong, and long-lasting composite in any number of shapes that’s often lighter than other solutions like steel and other metals.
But in order to allow the cured product to ‘release’ from the tooling after curing, mandrels and bladders must first be sleeved with heat shrink tubing. This tubing is the ideal alternative to more traditional — and extremely manual — options that include hand-taping of tooling or the use of adhesive release tapes that are fairly common in aerospace and manufacturing industries.
Beyond its use as a release layer, heat shrink tubing can be put to work as a wear-resistant cover for different products and applications. It can also be used as a dielectric protection barrier in applications such as electric vehicle batteries and other power supply applications. Different materials should be used depending on the application, so let’s explore three specific options — all of which are available at Dunstone — to help you find the right one for your requirements.
Ideal for use as a release layer, our FEP heat shrink tubing features an extremely controlled shrink process of just 10%. This low shrink percentage and force allows the tubing to properly fit the type of tooling being used without impacting its shape, which is particularly useful when the tooling is inflatable. The tubing begins to shrink at 35ºC (100ºF) and will continue to perform reliably as temperatures increase — even up to 260ºC (500ºF). FEP tubing will also shrink up to 66% faster than competing solutions, reducing the amount of time needed for labor and tooling preparation. Our FEP material is available in larger sizes than many other companies that offer extruded tubing.
Our heat shrink tubing is already one of the thinnest materials available on the market, featuring a wall that’s only 0.002 in. thick versus competing solutions that start at 0.004 in. Our thinner wall design allows the tubing to perform exceptionally well even when placed over an inflatable bladder, reducing the possibility of distortion. With our FEP line, the lower shrink force enables better bladder expansion during cure cycles, which reduces porosity inside composite parts.

In addition to our FEP line, Dunstone also offers two additional heat shrink tubing materials that feature higher shrink percentages for use in other applications.
Whereas FEP is better suited for production applications as a release layer over tooling, PVC heat shrink tubing increases the shrink percentage possible — allowing it to be used as a wear-resistant covering for packaging or for permanent sleeving requirements. The shrink percentage increases from the 10% possible with FEP to around 70% — allowing the material to be extremely form-fitting without losing any length. It is more cost-effective than other solutions and, along with all Dunstone heat shrink tubing, can be produced for your unique application.
PET heat shrink tubing provides the highest-possible shrink percentage of the three options — as much as 75%. Shrinking begins at a higher temperature than our FEP product (typically around 60ºC or 140ºF) and proceeds more slowly. Due to its chemical makeup, PET heat shrink tubing is often used as a protective barrier and for applications in which dielectric protection is needed. Along with our other heat shrink tubing material options, PET tubing is linear-seamed to provide flexibility in sizing.
At Dunstone, we take great pride in customizing our heat shrink tubing products according to our customers’ needs. It all begins by discussing your application and process with our expert team. From there, we will develop a solution designed to eliminate manual processes, reduce waste, eliminate foreign object debris (FOD), increase manufacturing efficiency, and promote stronger post-cure product results. That said, our products are already designed from the beginning to be more advantageous for your production needs.
Diameters and lengths are also extremely customizable. For diameter, sizes are available from 64 mm layflat width up to 320 mm for FEP tubing, and 10 mm lay flat up to 300 mm widths for PVC and PET, ensuring that no matter the size of your tooling, we have a heat shrink tubing solution to accommodate it.
And when it comes to length, we can produce continuous-length spools up to 2,000 feet or longer. This extended spool length ensures that you not only have all the material you need to stay productive but also benefit from cost savings due to buying more material upfront. The longer spool length also eliminates the need for your team to deal with splicing, as you can simply extract the length of heat shrink tubing needed for your composite parts. And no matter the diameter shrink percentage you’re working with, you can rest assured that the length of the tubing won’t shrink as heat is applied.
Whether you’re tired of dealing with hand-taping or are looking to improve quality during the curing process, our heat shrink tubing products are the industry’s best solution for achieving the results you want.

", "content_plain": "Creating Stronger Products for Better Results Heat shrink tubing is an essential component for multiple industries, ranging from aerospace and automotive component manufacturing to battery production and even sporting goods. In these industries, the end products being manufactured need to have a specific shape, surface finish, and overall high level of performance in order to withstand the often harsh conditions to which they’re exposed. This is achieved through the use of tooling such as mandrels, inflatable bladders, and SMART Tooling™ — formable, reusable tooling solutions for parts with complex geometries. Tooling serves as the ‘mold’ for a composite matrix layup or prepreg — a combination of multiple layers of a reinforcement matrixl like carbon fiber or Kevlar™ along with a specific resin system. Together, these materials are heated and compressed during a curing cycle to form the finished product — an extremely resilient, strong, and long-lasting composite in any number of shapes that’s often lighter than other solutions like steel and other metals. But in order to allow the cured product to ‘release’ from the tooling after curing, mandrels and bladders must first be sleeved with heat shrink tubing. This tubing is the ideal alternative to more traditional — and extremely manual — options that include hand-taping of tooling or the use of adhesive release tapes that are fairly common in aerospace and manufacturing industries. Beyond its use as a release layer, heat shrink tubing can be put to work as a wear-resistant cover for different products and applications. It can also be used as a dielectric protection barrier in applications such as electric vehicle batteries and other power supply applications. Different materials should be used depending on the application, so let’s explore three specific options — all of which are available at Dunstone — to help you find the right one for your requirements. 3 Solutions for Heat Shrink Tubing FEP (Fluorinated Ethylene Propylene) Ideal for use as a release layer, our FEP heat shrink tubing features an extremely controlled shrink process of just 10%. This low shrink percentage and force allows the tubing to properly fit the type of tooling being used without impacting its shape, which is particularly useful when the tooling is inflatable. The tubing begins to shrink at 35ºC (100ºF) and will continue to perform reliably as temperatures increase — even up to 260ºC (500ºF). FEP tubing will also shrink up to 66% faster than competing solutions, reducing the amount of time needed for labor and tooling preparation. Our FEP material is available in larger sizes than many other companies that offer extruded tubing. Our heat shrink tubing is already one of the thinnest materials available on the market, featuring a wall that’s only 0.002 in. thick versus competing solutions that start at 0.004 in. Our thinner wall design allows the tubing to perform exceptionally well even when placed over an inflatable bladder, reducing the possibility of distortion. With our FEP line, the lower shrink force enables better bladder expansion during cure cycles, which reduces porosity inside composite parts. Get more insights: Download the FEP product data sheet for additional information. In addition to our FEP line, Dunstone also offers two additional heat shrink tubing materials that feature higher shrink percentages for use in other applications. PVC (Polyvinyl Chloride) Whereas FEP is better suited for production applications as a release layer over tooling, PVC heat shrink tubing increases the shrink percentage possible — allowing it to be used as a wear-resistant covering for packaging or for permanent sleeving requirements. The shrink percentage increases from the 10% possible with FEP to around 70% — allowing the material to be extremely form-fitting without losing any length. It is more cost-effective than other solutions and, along with all Dunstone heat shrink tubing, can be produced for your unique application. PET (Polyethylene Terephthalate, or Polyester) PET heat shrink tubing provides the highest-possible shrink percentage of the three options — as much as 75%. Shrinking begins at a higher temperature than our FEP product (typically around 60ºC or 140ºF) and proceeds more slowly. Due to its chemical makeup, PET heat shrink tubing is often used as a protective barrier and for applications in which dielectric protection is needed.

Learn more about its advantages here.", "content": "A variety of industries — particularly those manufacturers working with rubber — use woven nylon tape to apply compaction during their vulcanization process. Also referred to as sail cloth or wrap tape, woven nylon tape is a consistent choice because it’s not a one-time-use product. It can be rewound after a curing cycle (provided that those cycles weren’t high-temperature), often allowing up to several uses before it must be discarded. While more costly than other solutions, this advantage has made it a go-to material for applying compaction.
However, as with many other industries, companies that produce woven nylon tape and cotton strapping are experiencing production delays due to material and labor shortages. For their clients that need compaction solutions to maintain their own productivity, this is a significant concern. Fortunately, other solutions are available beyond woven nylon tape that can be used for compaction and vulcanization needs — and provide additional value-added benefits.
Hi-Shrink Tape is a heat-shrinkable tape that applies compressive force to a layup. It is most often made of polyester, ETFE, and polyimide. Unlike woven nylon tape and other non-shrinking films like cellophane and polypropylene, Hi-Shrink Tape does not relax as curing temperatures rise. Instead, even greater compressive force is applied to the layup or product as the temperature rises, ensuring consistency and an overall more uniform output. Here are several key advantages of Hi-Shrink Tape over woven nylon tape.
While both material types can be applied using machines, Hi-Shrink Tape is generally faster and easier to apply because it can be produced on different-size cores. This enables both hand taping as well as use of automation equipment like winders, making Hi-Shrink Tape a more viable solution for production facilities with high throughput. It’s even available on traverse-wound spools for processes that require continuous lengths of tape. Additionally, if heat and pressure are the only variables involved in an application, Hi-Shrink Tape and an oven are all that is needed — replacing the need for an autoclave.
When applied, woven nylon tape or cloth will only provide compaction according to the tension with which it is applied to the layup or product. Additional layers of the material are needed as well to provide more compression. As temperatures increase during the curing process, the nylon will begin to relax — right when the resin or rubber begins to drop in viscosity and flow. It’s at this moment that greater compressive force is needed, and that’s exactly what Hi-Shrink Tape provides. This alternative material applies greater force as curing temperatures increase, ensuring the result is properly laminated and free from voids, volatiles like gasses or vapor, and other foreign object debris. Additionally, Hi-Shrink Tape does not require the same wrapping tension that woven nylon does in order to achieve the same compaction — reducing unnecessary strain on equipment and workers.
Because multiple layers of woven nylon cloth are needed to apply compression, more of the material is needed upfront. Even though it’s often reusable, that reusability eventually ends and more material must be purchased. Hi-Shrink Tape is significantly thinner than nylon tape (available even down to 1 mil, or one-thousandth of an inch), you get more of the material on your cores, allowing you to maintain your productivity and increase product quality with less material overall. You also get the same level of compaction force with less tape as well. While Hi-Shrink Tape is not reusable, this benefit of having more tape upfront that applies more force ensures you’re ready for any project.
With woven nylon tape, what you see is essentially what you get. While there may be some customization between suppliers and applications, it simply doesn’t compare to Hi-Shrink Tape, which offers significantly more flexibility. A variety of thicknesses are available ranging from 1 mil to 5 mils, generally increasing in shrink force with thicker variations (around 5–20% with additional customization available). Options are available as well that apply more force with higher temperatures all the way up to 752ºF (400ºC). And, Hi-Shrink Tape is available in both release-coated and non-release-coated options. Release coating allows the tape to be more easily removed from the layup after curing. Some tapes are available with perforations as well, allowing layups to expel gasses and vapors as the tape shrinks.
Dunstone has been manufacturing Hi-Shrink Tape for multiple industries nationwide for decades. If you’ve traditionally been using woven nylon tape for your compaction needs and are experiencing supply difficulties, our Hi-Shrink Tape offers the compaction, usability, and customization you need to make your application a success. With rolls up to 20” wide and overall lengths upward of 1,200 yards available, we’ll tailor a compressive tape solution specific to your application and continue to deliver the materials you need to provide high-performing, reliable products for your customers.

Unravel the benefits today.", "content": "In the shrink tape industry, tape is traditionally wound in a single direction around a core (which itself is a sliced portion of a tube or spool that matches the desired tape width), creating the standard roll of tape we’re all familiar with. However, companies with high-throughput production environments may have a need for longer, continuous lengths of shrink tape — much like wire and other materials. This is where traverse winding comes into play.
With traverse winding, the material is wound laterally around a spool or core. The winding mechanism moves from side to side, evenly distributing the material onto the spool in multiple layers until the desired amount or length has been wound. This process requires absolute precision so the appropriate tension is applied and the tape is wound properly around the spool.
A key difference with traverse winding when it comes to shrink tape is that the winding mechanism can’t move side to side. Whereas other tension-wound materials are wrapped around a stationary spool by the device moving side to side, traverse-wound tapes instead have the spool move under the fixed input of the material.
This is because flat materials like shrink tape require consistent lay to avoid imperfections. If the winding mechanism moved from side to side, the tape might stretch on different sides, resulting in deformities that will impact the product when the tape is applied.
In high-throughput environments, consistent production is an absolute to meet and exceed goals. Workers don’t have time to manually apply shrink tape to larger products, and because shrink tape typically comes on cores, workers would have to deal with numerous rolls — adding to the time needed to complete a lay-up.
With traverse winding, shrink tape can be ordered on a spool with longer and continuous lengths. This makes application vastly more efficient as it doesn’t require workers to change out the material as frequently, and because the tape can be applied to products for longer periods and even with greater consistency. Tape can still be applied by hand if needed, but the advantage of not having to change out the spool as frequently still stands.
While materials such as cellophane, nylon, and polypropylene provide compression only during the process of application under tension, during cure cycles they lose compression strength as the temperature rises. This phase is critical to the resulting quality of the resin, and less-than-ideal performance can result in voids or inconsistencies in the layup.
With our Hi-Shrink Tape, compression begins at 70ºC (158ºF) and reaches maximum force at 120ºC to 180ºC (248ºF to 356ºF; higher temperatures up to 400ºC are available). This ensures that as the temperature rises, our tapes’ pressures increase as the resin cures — resulting in a cured resin that’s free from voids and surface defects.
Our shrink tapes are available in a variety of thicknesses to ensure you have the right amount of compressive force for your application. Thicknesses ranging from .001” (1 mil) to .005” (5 mils) are available with shrink percentages ranging from 5% to 20% and max shrink force at peak temperatures ranging from 1.65 up to 21.64 pounds of pressure.
Many of our shrink tapes are also available with release coatings, which are designed for applications in which the tape needs to be removed after the composite material has finished curing. This makes removing the tape simple and also helps to move excess resin away from the composite during the curing cycle. Many of our release-coated shrink tapes are available with 1- or 2-sided coatings.
In many applications, composite layups and wet-winds produce volatiles like gasses and vapors that must be allowed to escape from the matrix. If not, they’ll create bubbles and other issues or prevent the matrix layers from bonding. To solve this, our 200 Series shrink tapes are available in perforated versions that allow these volatiles to escape (also called outgassing).
Whether you need a quick-and-easy solution for minor compressive force or an extremely high-temperature tape, our team is here to help.

These tools are placed in the lay-up for the composite material to take a particular shape, such as being hollow, having ridges, a circular or oval shape, and so on. However, these tools must be removed from the lay-up after curing. In applications where the product would be smaller, a standard heat-shrinkable release tape might be used. But in industries like aerospace where the resulting product is often long or features numerous tools as part of a single lay-up, FEP tubing is the ideal solution.
Applying and removing FEP tubing is much faster and simpler because the tube sleeves the mandrel or bladder as opposed to hand-taping, which is more time-consuming, leaves the risk of insufficient coverage, and can even be more costly due to having to use more material. The tube is slid over a mandrel or other tooling system and placed in an oven to shrink, or heated with a heat gun to form to the tooling. As heat is applied, the material shrinks and the matrix lay-up can begin. The composite is then cured in an oven or autoclave. When this process is complete, the mandrel or bladder can be easily removed.
Release films such as FEP have been around for some time, but prior to their use, companies using mandrels and bladders in their lay-ups had to hand wrap them with release film/tape, or coat them in a liquid release agent before laying the composite and curing. Doing this required cleaning after curing, which added more time to the process. Additionally, hand-taping release films often resulted in foreign object debris (FOD) contaminants in the product. Dunstone developed FEP tubing to make this process faster and easier as well as to help companies produce cleaner and higher-quality composite solutions.
Recognizing the inefficiency that came with hand-taping tooling, Dunstone partnered with aerospace experts — one of the primary industries where large composite products are needed and where a solution would bring significant benefit — to come up with a new way of tackling this production process. Through our partnership, we developed both the FEP tube needed for the process and the equipment to make it.
For example, stringers — part of the shell of an aircraft — are long, typically ridged sections. Hand-taping each mandrel needed to shape a composite stringer would not only be a significant undertaking but also a time-consuming and expensive one. Uniformity would be reduced since multiple bands of release tape would need to be used, and ensuring consistent application would be challenging. And of course, the risk of FOD after curing would be higher, as operators would then have to remove multiple materials, including adhesive tapes used to secure the hand wrapped release film, from the ID of the cured stringers, which presents a high risk of becoming entrapped inside the cured part and are difficult and time-consuming to remove. With FEP tubing, this inefficient method for producing long composite products is completely avoided.

In addition to being an innovative developer of FEP tubing solutions, our line FEP shrink tubing features some advantages that can’t be found anywhere else. For example, our FEP tubing (made of release-film-grade fluorinated ethylene propylene) is exceptionally thin — only 0.050 mm (0.002”) versus competing 0.10 mm (0.004”) options. This ensures the least amount of space possible between the mandrel and the composite, resulting in a far more precise shape. For inflatable tooling like bladders, these thinner walls eliminate distortion, allow for better expansion during curing, and reduce porosity inside of the resulting part.
Dunstone is also one of the only companies worldwide that can produce FEP tubing with a 2-mil-thick wall at large diameters. With competing tubing, walls are typically twice as thick — creating a gap and increasing overall costs. Thicker variants of our FEP tubing are available, and we can produce tubes with outside diameters up to 8.0” based on your application goals.

Hand-taping each mandrel needed to shape a composite stringer would not only be a significant undertaking but also a time-consuming and expensive one. Uniformity would be reduced since multiple bands of release tape would need to be used, and ensuring consistent application would be challenging. And of course, the risk of FOD after curing would be higher, as operators would then have to remove multiple materials, including adhesive tapes used to secure the hand wrapped release film, from the ID of the cured stringers, which presents a high risk of becoming entrapped inside the cured part and are difficult and time-consuming to remove. With FEP tubing, this inefficient method for producing long composite products is completely avoided. Get the FEP tubing datasheet here. Why Work with Dunstone for Your FEP Tubing Requirements? In addition to being an innovative developer of FEP tubing solutions, our line FEP shrink tubing features some advantages that can’t be found anywhere else. For example, our FEP tubing (made of release-film-grade fluorinated ethylene propylene) is exceptionally thin — only 0.050 mm (0.002”) versus competing 0.10 mm (0.004”) options. This ensures the least amount of space possible between the mandrel and the composite, resulting in a far more precise shape. For inflatable tooling like bladders, these thinner walls eliminate distortion, allow for better expansion during curing, and reduce porosity inside of the resulting part. Dunstone is also one of the only companies worldwide that can produce FEP tubing with a 2-mil-thick wall at large diameters. With competing tubing, walls are typically twice as thick — creating a gap and increasing overall costs. Thicker variants of our FEP tubing are available, and we can produce tubes with outside diameters up to 8.0” based on your application goals.", "image": "https://www.shrinktape.com/wp-content/uploads/2023/09/fep-style-rev-1-copy-web-2.jpg", "modified": "2026-03-24T13:44:37-05:00" }, { "id": 4143, "type": "post", "url": "https://www.shrinktape.com/resources/news/perforated-tape-sticking-to-the-facts/", "title": "Perforated Tape: Sticking to the Facts", "h1": "Perforated Tape: Sticking to the Facts", "summary": "Perforated tape is often misunderstood as allowing bleed-out when it’s actually designed to allow gaseous volatiles to escape from resins. Learn more here.", "content": "Composite materials — carbon fiber, fiberglass, kevlar, PEEK, and others — are used in numerous industries worldwide for countless products ranging from sporting goods and auto parts to household goods and even energy-related applications. And thanks to their strength, temperature resistance, chemical resistance, and other advanced features over traditional materials like steel, their use will only continue to grow.
A common application for composite materials is the production of various types of tubing. To ensure these materials deliver the high levels of performance their customers expect, companies using composites in their production — whether it’s a wet layup process or using prepregs — must rely on resin between the material layers to create the necessary bond and compress them. This is to de-bulk the end product, eliminate voids and air pockets, and ensure the material is defect-free.
One of the most common solutions today for successful compaction is hi-shrink tape, which constricts the underlying structure as heat is applied during the curing process. The tape is wrapped around the material — with sufficient overlap to ensure proper compaction — and placed in an oven, where it begins to shrink.
As a result, the pressure applied by the tape forces resin through the composite matrix and between the layers of the material, bringing them as close together as possible and filling any voids. And while the resin plays a key role in achieving a tight bond, oftentimes it is important to de-bulk as much as possible.
Hi-Shrink tapes come in various versions, release coated, non-coated, and perforated. Perforated release films are commonly used in the composite industry to help remove resin away from the composite surface and onto bleeder cloth where the resin is soaked up. Perforated shrink tapes are often sought out for the same reasons a processor wants to use perforated release films. This is where the most common misconception about perforated tape arises: often, the perception is that perforated tape will allow the excess resin to escape through the perforations. While there may be some squeeze-out through the perforations, this is unlikely and isn’t the intended use of the tape. (Despite the perforations, the true bleed-out will occur between the tape layers, where it can then be removed with the tape after curing — if the tape is to be removed at all.)
The true benefit of perforated tape is due to what’s happening in the material: certain composite layups and wet-winds will produce volatiles — gasses and vapors — that must be allowed to escape, otherwise, they’ll create imperfections like bubbles, dry spots, or de-lam (when parts of the matrix aren’t bonding) that can impact material performance. This is where perforated tape excels. Allowing the volatiles to escape the layup contributes to more uniformity in the lamination and overall consolidation of the composite material layers. And the more outgassing involved, the more beneficial perforated tape will be.
Our guide to Hi-Shrink Tape is packed with product details, application recommendations, and more.
Download HereA Dunstone customer in the manufacturing space was using composite material to produce utility poles — a solution where climates, insects, location, and other factors make using wood poles unfavorable. The company was using a wet layup process in which individual fibers were being wrapped around a core that is removed after curing.
During the early stages of production, a significant amount of resin was added to the fibers to achieve full saturation. This was then wrapped with more material followed by more resin. Once the product reached the desired outside diameter for fiber content, the company wrapped it in non-perforated hi-shrink tape ahead of oven curing.
While this standard shrink tape was working well and led to proper consolidation of material, they were still getting voids in the layup fibers and dry spots on the surface. This was due to their particular resin producing substantial gaseous volatiles that were getting trapped under the tape. Apart from the appearance and structural issues this posed, it was also problematic because the pole surfaces weren’t painted or otherwise covered up — the post-cure product was what their customers received.
They contacted Dunstone looking for a solution to improve surface consistency and structural integrity while eliminating these voids in the matrix. We recommended our perforated tape, and immediately upon the company’s next run of poles, there were no voids in the matrix or surface dry spots.

For more than 60 years, Dunstone has been producing multiple lines of innovative shrink tapes and films for multiple industries. Our 200 Series, in particular, is ideal for perforation tape needs, and our 200 line is available in widths from 0.5” to 2.5” as standard (custom widths up to 20”) with a 0.02” thickness that minimizes the height of leftover lines (aka “cello lines”) on cured parts, keeping surface appearance consistent. It is suitable for cure temperatures up to 165ºC (330ºF). For perforated tape needs, our 220R and 220S specific products are ideal.
More importantly, however, we can customize the shrink percentage on this tape to suit your needs. Percentages range from 5% to 20% and are tailored to your unique application based on the amount of compaction force required. The 200 Series is also available in uncoated, 1-side release coated, or 2-side release coated variants.

The vulcanization of rubber cylinders isn’t new technology. As far back as 1821, inventors like James Boyd and captains of industry like Charles Goodyear experimented and eventually learned how to vulcanize rubber for products like rubber-lined hoses. The latter of which is credited with discovering the process of vulcanization itself.
Vulcanizing rubber is the process of using heat, pressure, steam or a combination of the three to form cross-links between long rubber molecules in order to improve resilience, tensile strength, viscosity, hardness and weather resistance. Many types and durometers of rubber are used in the manufacturing of:
Among the various applications and rubber types, there are some basic principles necessary for achieving the desired result of a continuously laminated, and in many cases reinforced, rubber cylinder. Though methods may vary, a common set of variables present in a large number of these applications is that of heat and pressure. Enough heat is required to drop the viscosity of the rubber in use so that it can be forced to amalgamate with itself through the use of pressure. The end result is one solid part.
In some cases, an autoclave or vulcanizer is used to achieve both heat and pressure simultaneously. In other instances, wrapping or curing tapes, are used to provide external compression on the outer surface of the cylinder. For high-performance hoses, rollers or belts these methods are often combined for maximum effect. The addition of cure wrap tape, also called hose wrap tape, can be necessary for a number of reasons. It may be required to process a room temp vulcanization (RTV cure) of a part where no heat is necessary, and an autoclave is not available. In addition, it may be required due to a number of other factors such as higher durometer rubbers, large cylinders or dense laminations for heavy duty parts like commercial rollers and industrial chemical hoses.
![\"how](\"https://www.shrinktape.com/wp-content/uploads/2023/09/rubber-hoses-1024x439.jpg\")
Whatever the reason, there are a few different varieties of wrapping or curing tapes. Some are flat films like polypropylene, nylon 66, polyester or pfa. Some cure wrap tapes are woven nylon or other polys. The flat films are generally one-time use, easy to apply with automated equipment or by hand. They are flexible and low cost but can become expensive when multiple layers of tape are required, or the tape becomes brittle and difficult to remove and requires additional labor.
On the other hand, woven hose wrap tapes are thick, durable and flexible enough to make gentle bends and undulations in the surface of the part. These fabrics are generally multi-use to make up for their relatively expensive costs. One of the biggest expenses of woven curing tapes is the labor involved in their removal, cleaning, re-spooling and re-use. In many cases, additional layers of release-able films and stretch films are used to aid in the compaction of the underlying part. Though both of the methods have pros and cons, we think a better solution exists.
Dunstone customers have relied on hi-shrink curing tapes for decades because of their superior functionality on hi-performance, and high-volume rubber hoses, rollers and belts. The ability to optimize the shrink percentage and compaction force in a single layer means that not only do they generally use about half the material when compared to other wrapping and curing tapes, but they also process in less time.
The ability to optimize compaction force at a given temperature is the key here. By modifying the shrink percentage, tape overlap, and application tension, our customers can precisely target the ideal amount of compressive force placed on their part when their specific compound is flowing. Whether you need massive amounts of force or a very precise small amount of force, it is possible with Hi-Shrink Tape. The end result is high-quality lamination and vulcanization, fewer defects and rejects, and generally lower cost. You also have the ability to achieve a smooth outer surface free of defects with a tape that is just as easy to remove as it is to apply.

We take a deep dive at what kind of challenges compaction films face and how shrink tape can help mitigate them", "content": "The world of tape wrapping composite tubes isn’t new. There have been a variety of methodologies over the past half century to apply pressure to the outside of a mandrel wrapped composite tube. Most of these methodologies revolve around what we call compaction film. These are generally non-shrink or low-shrink polypropylene, nylon, cellophane etc. The theory is to wrap a part under the maximum tension the tape will permit at a steep pitch of usually just a few millimeters. There are, however, a few challenges with the age-old process for compaction tubing.
The first and most significant is that all of the compaction force that part will ever see is during a dry, room temperature layup where the resin is at it’s highest viscosity and no heat is applied. The reality is that even at 40+ pounds of taping tension, once the part is introduced to the oven for cure, these tapes all relax at typical curing temperatures. This happens while the resin viscosity is dropping, which is not ideal for appropriate lamination and low porosity.
The second challenge with traditional compaction films relates to yield and time consumption. With steep pitches and often several passes of over-wraps to generate in-spec parts, a large volume of tape is required and the process to remove tapes after cure can be time consuming. Many manufacturers of composite tubing rely on throughput to keep their process and products profitable.
![\"\"](\"https://www.shrinktape.com/wp-content/uploads/2023/09/shrinkforceplusvaluesplus20plusshrink.png\")
There are a few ways to deal with the challenges posed by compaction films for composite tubing. As you can see from the graph above, Dunstone’s Shrink Tape for composite tubing actually produces more force as temperatures elevate. The tapes are specifically designed to create the most force at the point where most common resin systems are at their lowest viscosity point. This ensures excellent consolidation and further reduces porosity by ensuring that every bit of material has resin forced through it at this critical stage in the curing cycle.

Take a deep dive into the unique properties of Dunstone’s advanced Shrink Tape technology — and see for yourself how it outperforms traditional compaction films to improve the integrity of your composite tubing.
Learn even more about how Dunstone’s Shrink Tape can help you overcome the challenges of traditional compaction films in our free downloadable eBook.
As can be seen in the video below, the challenge of time and yield waste is addressed in two ways. First, our shrink tape for composite tubing is engineered to work best at 50% overlap (though more or less overlap can significantly affect the pressure/square inch applied to the underlying part). This means that with a 1.00” wide tape, all that is necessary is a 0.50” overlap, taped at moderate tensions of 5-8 lbs, to produce excellent results.
By comparison a 6-foot tube, 1.00” in diameter might consume ~246’ of 1.00” wide nylon at a 2mm pitch, single pass. The same part wrapped at 50% with Dunstone’s Hi-Shrink Tape would only consume 38’ of 1” wide tape. The reduction in applied material means a reduction in application time and less waste in landfills. Further reducing time and processing costs, our tapes come with an optional release coating that allows for easy removal of the tape post cure. You will find that our release coat works with most common resin systems.

", "content_plain": "The Challenges of Compaction Films for Composite Tubes The world of tape wrapping composite tubes isn’t new. There have been a variety of methodologies over the past half century to apply pressure to the outside of a mandrel wrapped composite tube. Most of these methodologies revolve around what we call compaction film. These are generally non-shrink or low-shrink polypropylene, nylon, cellophane etc. The theory is to wrap a part under the maximum tension the tape will permit at a steep pitch of usually just a few millimeters. There are, however, a few challenges with the age-old process for compaction tubing. The First Challenge: Weak Compaction Force The first and most significant is that all of the compaction force that part will ever see is during a dry, room temperature layup where the resin is at it’s highest viscosity and no heat is applied. The reality is that even at 40+ pounds of taping tension, once the part is introduced to the oven for cure, these tapes all relax at typical curing temperatures. This happens while the resin viscosity is dropping, which is not ideal for appropriate lamination and low porosity. The Second Challenge: Material Usage and Time The second challenge with traditional compaction films relates to yield and time consumption. With steep pitches and often several passes of over-wraps to generate in-spec parts, a large volume of tape is required and the process to remove tapes after cure can be time consuming. Many manufacturers of composite tubing rely on throughput to keep their process and products profitable. How to Avoid These Challenges and Improve Your Composite Tubing There are a few ways to deal with the challenges posed by compaction films for composite tubing. As you can see from the graph above, Dunstone’s Shrink Tape for composite tubing actually produces more force as temperatures elevate. The tapes are specifically designed to create the most force at the point where most common resin systems are at their lowest viscosity point. This ensures excellent consolidation and further reduces porosity by ensuring that every bit of material has resin forced through it at this critical stage in the curing cycle.

Learn More Today Find New Time and Material Savings with Dunstone Heat Shrink Tape As can be seen in the video below, the challenge of time and yield waste is addressed in two ways. First, our shrink tape for composite tubing is engineered to work best at 50% overlap (though more or less overlap can significantly affect the pressure/square inch applied to the underlying part). This means that with a 1.00” wide tape, all that is necessary is a 0.50” overlap, taped at moderate tensions of 5-8 lbs, to produce excellent results. By comparison a 6-foot tube, 1.00” in diameter might consume ~246’ of 1.00” wide nylon at a 2mm pitch, single pass. The same part wrapped at 50% with Dunstone’s Hi-Shrink Tape would only consume 38’ of 1” wide tape. The reduction in applied material means a reduction in application time and less waste in landfills.

Composite drive shafts and hybrid driveshafts are no longer relegated to high-end racing teams and the aftermarket audience. Global manufacturers like BMW, Porsche and Nissan have been using carbon drive shafts in some of their offerings for years while many more companies are planning integrations into mid-range, suv, compacts and sports cars over the next few years. The driveshaft is arguably one of the most critical components to the drive system, transferring the power of the motor to the wheels. It makes sense then, that these components must be rock solid and outperform their steel or aluminum counterparts. That is where Dunstone’s heat shrink solutions come in.
In the video below from QA1, you can see the process from start to finish. It is critical in this process that sufficient compaction on a very long part is generated to ensure the mechanical stability of the product. At about the 2:00 minute mark you can see the application of our film on a filament wound driveshaft blank. QA1 uses a steep overlap of our 220R 1” wide material to ensure they generate the maximum force necessary to capture the strength of those fibers in combination with the resin system. This is a perfect example of how our Hi-Shrink tape’s performance can be tailored to suit your application and specifications simply by modifying the application of the film itself.

Though the heat shrink release tubes generally come in FEP, they can also be made of ETFE or other release films at the customers request.
As opposed to standard taping of release film or using release tapes that stick to the bladder/tool, the ability to snuggly shrink a release tube down on the surface can save a substantial amount of prep time both before and after the cure cycle. In some instances the tubing can be used for more than one cycle. Dunstone is also actively working on near fit 3D sizing for the tubing allowing for the treatment of tapered components and more complicated geometries.
With the ability to precisely size components due to the method of linear seam manufacturing using flat film rather than an extruded tube, Dunstone can also manufacture long continuous lengths that will benefit any operation looking to automate the process of treating their part.

Release coating of silicone bladders with heat shrink tubing, replacing hand wrapping process
Often times, composite fuselage skins for aerospace structures use composite stringers to stiffen the composite skin. Many times these composite skins are co-cured at the same time as the composite stringers. Composite stringers with trapezoidal or omega shaped cross section, typically 20’-40’ in length, require an inflatable silicone bladder on the inner mold line to provide internal compaction during cure. It is necessary to cover the bladders with a release film prior to application of carbon fiber pre-preg, the release film allowing for removal of the tool after the autoclave cure cycle. The silicone bladders were wrapped by hand with release film, and taped into place using Teflon tape. This can be a costly and time consuming process required for each fuselage section, and it often resulted in difficulty removing the hand wrapped release film after part cure due to the adhesive tape becoming stuck on the ID of the cured stringer. Material that remains on the inside of the cured part has to be completely removed before the part can be cleared for subsequent processing. Re-work and labor to remove the trapped film is costly and needs to be eliminated.
Dunstone Hi-Shrink FEP Tubing used in the bladder preparation process allows the customer to prepare more parts in less time in order to incorporate them into the larger fuselage section prior to autoclave cycle. Our FEP tubing shrinks quickly, and without wrinkles, requiring less heat to fully shrink when compared to other heat shrink release film tubes. Dunstone Hi-Shrink FEP Tubing has uniform thickness which give it uniform shrink percentage throughout.

High Voltage Motors and Generators
Large OEM in the power generation industry looks to cost reduce their current release film.
Current film is expensive to use as a sacrifice layer and provides very little compaction when heated during the press cycle. Low compression force can lead to poor insulation consolidation and improper shaping of the corner radii on the HV coils.
Dunstone F-Series Hi-Shrink Tape with PVF Release
The OEM was able to use Dunstone’s F-Series Tape 210F as the first layer of release film instead of the film currently used. Hi-Shrink Tape 210F is a polyester based shrink film, with 10% shrink, which has a fused coating of Tedlar® on one side for release. The product provides the high temperature release characteristics of Tedlar®, combined with the high shrink force of polyester film at an overall lower cost.
Other applications for Dunstone tapes on high voltage coils
Aerospace Composites
Compress & de-bulk lightweight ducts used to transport air in commercial aircraft environmental control systems.
Composite ducts layed up on plaster mandrels require external compression during cure process to eliminate voids in duct walls. Manufacturers’ current process specified the use of a cellophane film, wrapped under high tension, to achieve sufficient compaction. After part cure at a temperature of 120°C, the cellophane stuck to the phenolic/glass prepreg, making removal of the film difficult and adding time to part processing. In addition to the difficulty in removal, the cellophane is a non-shrinking film, which tended to wrinkle the outer layer of prepreg on the part.
Release Coated Hi-Shrink Tape 220
Replacing the cellophane with Dunstone 220R allowed the operators to continue wrapping the film in the same manner, with lower tension during tape wrapping.
The shrink characteristics of the 220R enabled the tape to shrink and apply its max shrink force at the same time the resin viscosity is dropping, enabling the tape to minimize resin voids between the plys and reduce prepreg wrinkling.

Because Dunstone’s Hi-Shrink Tape is entirely adhesive-free, once lamination is achieved, the tape can be easily removed with no residue left behind. Step By Step Instructions for Selecting and Using Heat Shrink Tape The first step is to identify the right type of Hi-Shrink Tape for your application. Basic applications won’t need shrink tape with significantly high compressive force or shrink percentages, whereas others might. Determine whether you need a release coating. Depending on your resin system, you may need a release-coated Hi-Shrink Tape that allows the tape to be easily removed from the part post-cure. Find the right taping tension for your application, otherwise known as how tightly you wrap Hi-Shrink tape around your product. Typically, those who are hand-wrapping shrink tape use between five to eight pounds of force. Be consistent with your tension as you overlap the tape. Some applications only need 25% overlap, but others can benefit from higher overlap at 50% or 75%. Secure the tape to the part prior to curing. Hi-Shrink Tapes don’t use an adhesive on either side, so they can be secured at either end with regular adhesive tape. Have questions about using using heat shrink tape?
