Polyshrink Film

Polyshrink and Freebond Shrink/Release Films used for processing high voltage coils and composites.

Electrolock’s Polyshrink and Freebond shrink and release films are custom designed to optimize compaction forces during the cure cycle of high voltage coils and electrical composites. Before selecting the correct film, thickness or shrink percentage, Electrolock first understands your composite structure. The goal is to apply the correct compaction force to the part during the cure cycle, increasing resin flow and reducing voids in the finished part.

Electrolock can choose from PET, FEP, Polyimide and other films to match the cure temperature of your part. Polyshrink films are supplied with our proprietary “non-silicone” release coating on one or both sides of the film, ensuring an easy release off of the cured high voltage coil or part.

Your custom solution is only a click away.
