ETFE film is used in release applications because it offers excellent weatherability and is stronger than PFA and FEP. ETFE film has a continuous use temperature of 330°F (165°C), suitable for cryogenic and high temperature applications.
We offer three different options for ETFE film:
|Material||Use Temperature||Tensile Strength||Elongation||Modulus||Tear Resistance||Density||Coeff. of Friction||Chemical Resistance||Abrasion Resistance||Light Transparency|
ETFE-E2 film is manufactured from a copolymer of ethylene and tetrafluoroethylene resin and offers an operating temperature of -328°F to 330°F (-200°C to 165°C). ETFE-E2 is a general purpose film that combines the outstanding chemical and thermal flexibilty of fluoropolymer with the improved mechanical performance of advanced engineering grade plastics, making it an excellent candidate for a wide variety of applications.
ETFE-E4 and LM (low melting) fluoropolymer films are manufactured from specialty grades of of ethylene and tetrafluoroethylene copolymers. These grades are designed to be highly extensible and formable at all manufacturing temperatures when compared to ETFE-E2 film.
ETFE-RF, release grade film, is a clear or pigmented film manufactured from a copolymer of ethylene and tetrafluoroethylene resin. CHEMFILM ETFE-RF release film is commonly used in composite molding aerospace applications because the low-gel surface of the film offers a smooth part finish on molded components.
