The Tape is Only as Good as the Supplier

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.

3 Criteria for the Right Polyimide Tape Supplier

1. Overall Product and Material Availability

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.

2. Tailored Shrink and Compression Performance

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.

3. Tape Customization Capabilities

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.
