ETFE E2 General Purpose

ETFE Fluoropolymer film made from ethylene tetrafluoroethylene copolymer resin, with excellent non-stick/release properties, thermoformability, weatherability and light transmittance.

ETFE E2 General Purpose

ETFE E2 General Purpose film can be used in diverse and demanding applications like dry-erase writing surfaces, protective laminates for outdoor graphics, and front sheets in photovoltaic (PV) cells. Non-stick, self-cleaning, and heat-sealable, C-treated bondable versions are also available.

Offering exceptional chemical and thermal resistance, ETFE E2 General Purpose film offers excellent weatherability, low haze, and high clarity. Thermoformable and available in a cementable (surface-treated) form and product thicknesses of 0.0005” – 0.010” (12.7 µm – 0.254 µm), its technical properties lend themselves to various specialist applications. High light transmission, UV stability, and bondability to encapsulants make it an ideal material for photovoltaic frontsheet films. Adhesives can also be applied to the C-treated surface in its surface-treated form – making it an excellent protective overlay for outdoor graphics, with high clarity and light transmission. It is also available with a matte surface texture to reduce gloss and surface reflections.

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.
