ETFE Release Films

ETFE Pigmented fluoropolymer film manufactured from ethylene tetrafluoroethylene copolymer resin that is an ideal release solution for composite molding resin systems at high temperatures.

ETFE RF Release Film

With a non-stick surface and high chemical resistance and elongation, our ETFE RF Release film is designed to provide reliable, high-quality release performance for resin systems operating at up to 356˚F (180˚C). Available in both translucent pigmented and perforated forms.

Specially designed to give high levels of performance in the composite molding process, our ETFE RE film works as a versatile release film. High elongation means it can conform to mold contours of any shape and complexity in order to provide a non-stick and chemically resistant surface. Manufactured to handle temperatures of up to 356˚F (180˚C), these pigmented films increase visibility to speed removal from parts and molds to reduce the risk of foreign object contamination occurring downstream. We also have a perforated form available that can provide further control over outgassing and resin bleed to help ensure consistent product quality, high throughput, and enhanced productivity.

ETFE Matte Films

With a matte surface texture on one side having an Ra surface roughness of approximately 2-3 microns, our ETFE matte films are an effective way of reducing the glare from PV frontsheets. They can also transfer a matte or low gloss surface to molded parts during the composite or electronics molding process.
