ETFE MELT EXTRUDED FLUOROPOLYMER FILMS

TCI’s ETFE films/foils are produced from ethylene and tetrafluoroethylene co-polymer resin using a melt extrusion casting process. These films have a low permeability to liquids, gases, moisture, and organic vapors with a high elongation and tear resistance. ETFE foils can be heat-sealed, thermoformed, and laminated to various substrates. TCI’s films are free of plasticizers, processing aids, or additives. Our ETFE films have excellent light transmission (>90%) and clarity with a high transmittance of ultraviolet and all wavelengths, except far infrared. These films have excellent non-stick/release properties and superior weatherability in outdoor exposure. TCI’s ETFE foils are ideally suited for architectural, photovoltaic-solar, and mold release applications.

TCI offers ETFE films/foils in thicknesses ranging from 0.0005″ to 0.010″ (12 to 250 mμ), with a standard width of 60” (1,524 mm). The maximum width available for ETFE films is 62” (1,575 mm). Slit widths are available upon request. These films have a high dielectric strength: 5,500 V/mil for 1-mil film (215 kV/mm for 25 mµ film). ETFE foils have a broad continuous use temperature range between -328°F and 330°F (-200°C to 165 °C). ETFE films are reliable with a short-term exposure temperature up to 400°F (204°C) and a melt temperature minimum of 500°F (260°C). Bondable (plasma treated or chemically etched) surfaces are available.
