Ethylene tetrafluoroethylene (ETFE) filastik ne na tushen fluorine.An ƙera shi don samun juriya mai girma da ƙarfi akan kewayon zafin jiki mai faɗi.ETFE polymer ne kuma tushen tushen sunan sa shine poly (ethene-co-tetrafluoroethene).ETFE yana da ingantacciyar yanayin zafi mai narkewa, ingantacciyar sinadarai, kaddarorin juriya na wutar lantarki da makamashi mai ƙarfi.Lokacin da aka kone, ETFE ta saki hydrofluoric acid.
Ana iya samun fa'idodin kwatancen tebur na PTFE akan FEP, PFA da ETFE akan gidan yanar gizon DuPont, jera kayan aikin injiniya, thermal, sunadarai, lantarki, da kaddarorin tururi na kowanne, gefe da gefe.
ETFE shine ingantaccen sigar ƙarfi mai ƙarfi na sauran ukun a cikin wannan rukunin, galibi yana nuna ƙarancin ƙarfi a wasu fagage ta kwatanta.
