Ethylene tetrafluoroethylene (ETFE) ipurasitiki ine fluorine-based.Yakagadzirwa kuti ive nepamusoro corrosion resistance uye simba pamusoro petembiricha yakawanda.ETFE ipolymer uye zita rayo-rinobva kune poly(ethene-co-tetrafluoroethene).ETFE ine tembiricha yakanyungudika, yakanakisa kemikari, magetsi uye yakakwirira-simba remagetsi rekudzivirira zvivakwa.Kana yapiswa, ETFE inoburitsa hydrofluoric acid.
Anobatsira ekuenzanisa matafura ePTFE achipesana neFEP, PFA uye ETFE anogona kuwanikwa paDuPont's webhusaiti, achinyora mechanical, thermal, chemical, magetsi, uye mhute zvimiro zvechimwe nechimwe, padivi nepadivi.
ETFE inobudirira iyo yakakwirira-yakasimba shanduro yevamwe vatatu muboka iri, kazhinji iine zvishoma zvishoma zvishoma zvishoma kune dzimwe nzvimbo nekuenzanisa.
Kupisa kweETFE kunoitika nenzira yakafanana nehuwandu hwemamwe fluoropolymers, maererano nekusunungura hydrofluoric acid (HF).HF inoparadza zvakanyanya uye ine muchetura, saka kungwarira kwakakodzera kunofanirwa kuitwa.
ETFE firimu rinozvichenesa (nekuda kwekusabatika kwayo pamusoro) uye rinoshandiswazve.Inotarirwa ne punctures nemicheto yakapinza uye naizvozvo inonyanya kushandiswa pamatenga.Sefirimu yekuisa padenga inogona kutambanudzwa (kusvika ku3x) uye ichiri kuoma kana imwe shanduko muhukuru ikaitika (nekuda kwekuwedzera kwekushisa, somuenzaniso.) Kushandisa kupisa kupisa, misodzi inogona kugadziriswa nechigamba kana mapepa akawanda akaunganidzwa mukati. mapaneru makuru.
ETFE ine simba rinoda kusimba re42 MPa (6100 psi), ine tembiricha yekushanda ye89 K kusvika 423 K (−185 °C kusvika +150 °C kana −300 °F kusvika +300 °F).[3]
ETFE resins inopesana nechiedza che ultraviolet.Yekumhanyisa bvunzo yemamiriro ekunze (inofananidzwa nemakore makumi matatu kuratidzwa) yakaburitsa chero zviratidzo zvekuipa kwefirimu.
