ETFE
Sign in to saveEthylene tetrafluoroethylene (ETFE) is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. ETFE is a polymer, and its source-based name is poly (ethene-co-tetrafluoroethene). It is also known under the DuPont brand name Tefzel and is sometimes referred to as "Teflon Film".

Ethylene tetrafluoroethylene (ETFE) is a fluorine-based plastic. It was designed to have high corrosion resistance and strength over a wide temperature range. ETFE is a polymer, and its source-based name is poly (ethene-co-tetrafluoroethene). It is also known under the DuPont brand name Tefzel and is sometimes referred to as "Teflon Film". ETFE has a relatively high melting temperature and excellent chemical, electrical, and high-energy-radiation resistance properties. ==Properties== Useful comparison tables of PTFE against FEP, PFA, and ETFE can be found on Chemours' website, listing the mechanical, thermal, chemical and electrical properties of each, side by side. ETFE is effectively the high-strength version of the other three in this group.
ETFE film is self-cleaning (due to its nonstick properties) and recyclable. As a film for roofing, it can be stretched and still be taut if some variation in size, such as that caused by thermal expansion, were to occur. Employing heat welding, tears can be repaired with a patch or multiple sheets assembled into larger panels.
