    ETFE Films

    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:

    • CHEMFILM® ETFE-E2 General Purpose Film
    • CHEMFILM® ETFE-E4 and ETFE-LM Low Melting Film
    • CHEMFILM® ETFE-RF Release Film

    ETFE-E2 General Purpose

    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.

    BENEFITS:

    • Superior release properties, self-cleaning
    • UV stable: excellent outdoor weatherability
    • Excellent chemical and mechanical properties
    • Excellent for lightweight, transparent surface coverings and architectural openings
    • Thermoformable to shapes of moderate complexity
    • Available with pigment for easy identification
    • Available with C-treatment to provide a cementable surface on one or both sides of the film

    RELATED DOCUMENTS:

    • CHEMFILM ETFE-E2 datasheet
    • CHEMFILM ETFE safety datasheet

    RELATED APPLICATIONS: Photovoltaic frontsheets, Solar themal collection, Semiconductor encapsulation, Process belting and casting, Surface protection, Medical release

    CHEMFILM ETFE-E2 General Purpose

    ETFE-E4 and LM Low Melting

    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.

    BENEFITS:

    • Thermoformable to shapes of high complexity
    • Low force sliding characteristics against the most common vessel materials
    • Will not contaminate or react with many drugs and samples
    • Pinhole free: provides a suitable barrier to prevent container contamination
    • Available with C-treatment to provide a cementable surface on one or both sides of the film

    RELATED DOCUMENTS:

    • CHEMFILM ETFE-E4 and LM datasheet
    • CHEMFILM ETFE safety datasheet

    RELATED APPLICATIONS: Semiconductor encapsulation, Pharma closure

    CHEMFILM ETFE-E4 and LM Low Melting

    ETFE-RF Release 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.

    BENEFITS:

    • Easy de-molding prevents damage and contamination of parts and the mold
    • Temperatures suitable for moderate temperature resin systems in composite molding
    • Exceptional chemical resistance in aggressive environments
    • Available with pigment for easy identification, customized products
    • Available with C-treatment allows the film to be sealed easily to itself and other surfaces

    RELATED DOCUMENTS:

    • CHEMFILM ETFE safety datasheet

    RELATED APPLICATIONS: Composite molding, Wind turbine manufacturing
