ETFE (ethylene tetrafluoroethylene) is a fluorine based plastic. It is specifically designed to have a high corrosion resistance and strength over a wide temperature range. The tensile strength approaches 42 MPA. With a working temperature of -185 °C – 150 °C. When burned ETFE releases hydrofluoric acid, which is extremely corrosive and toxic.

ETFE

ETFE resin combines superior mechanical toughness with an outstanding chemical inertness that approaches that of fluoroplastic resins. Furthermore ETFE is resistant to ultraviolet light. It can be processed easily and features a specific gravity of 1.7, and high-energy radiation resistance. ETFE film is self-cleaning due to its nonstick surface.

ETFE can be heat sealed, thermoformed, vacuum formed, heat bonded, welded, metallized and laminated. This high-performance film is used in several industries, such as semi-conductor, aerospace, architecture and agriculture. Due to its exceptional durability, UV transparency and anti-fouling properties, it is used in outdoor architectural applications, greenhouses and solar cells.
