.003" Heat Shrink Polyester Tape

Hi-Shrink Tape is a tough, flexible, heat shrinkable polyester film.

When wrapped around an object and heated, Hi-Shrink Tape has the unique ability to shrink and apply pressure to the surface of composite parts. This simple method of pressure application is used to advantage in many industries. A perfect step up in compaction force for demanding applications. Our 300 Series shrink tapes provide more tensile strength and come with/without a release coat

Product Description:
