إيثيلين رباعي فلورو الإيثيلين

Also known as ethylene tetrafluoroethylene, poly(ethene-co-tetrafluoroethene)

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 mech
