ʻO ka Ethylene tetrafluoroethylene (ETFE) he plastic-fluorine.Ua hoʻolālā ʻia e loaʻa i ke kūpaʻa corrosion kiʻekiʻe a me ka ikaika ma luna o kahi ākea ākea.He polymer ka ETFE a ʻo kona inoa kumu kumu he poly(ethene-co-tetrafluoroethene).Loaʻa i ka ETFE kahi wela hoʻoheheʻe kiʻekiʻe, kemika maikaʻi loa, ka uila a me ka ikaika kiʻekiʻe o nā waiwai pale radiation.Ke puhi ʻia, hoʻokuʻu ka ETFE i ka waika hydrofluoric.
Hiki ke loaʻa nā papa hoʻohālikelike pono o PTFE e pili ana iā FEP, PFA a me ETFE ma ka pūnaewele o DuPont, e helu ana i nā waiwai mechanical, thermal, kemikala, uila, a me ka mahu o kēlā me kēia, ʻaoʻao.
ʻO ka ETFE ka mana kiʻekiʻe o nā ʻekolu ʻē aʻe i loko o kēia pūʻulu, e hōʻike pinepine ana i nā mana i hōʻemi iki ʻia ma nā kahua ʻē aʻe ma ka hoʻohālikelike ʻana.
Hana ʻia ka puhi ʻana o ETFE ma ke ʻano like me ka nui o nā fluoropolymers ʻē aʻe, ma ke ʻano o ka hoʻokuʻu ʻana i ka waika hydrofluoric (HF).He ʻino loa ka HF, a no laila pono e mālama pono.
Hoʻomaʻemaʻe ʻia ke kiʻi ʻoniʻoni ETFE (ma muli o kona ʻili nonstick) a hiki ke hana hou ʻia.He mea maʻalahi ia i nā punctures e nā kihi ʻoi a no laila hoʻohana nui ʻia no nā hale.Ma ke ʻano he kiʻiʻoniʻoni no ka uhi ʻana, hiki ke kau ʻia (a hiki i 3x) a paʻa mau inā loaʻa kekahi ʻano like ʻole o ka nui (ma muli o ka hoʻonui ʻana i ka wela, no ka laʻana.) Ke hoʻohana ʻana i ka wili wela, hiki ke hoʻoponopono ʻia nā waimaka me kahi ʻāpana a i ʻole nā lau he nui i hui ʻia i loko. nā panela nui.
He 42 MPa (6100 psi) ka ikaika uʻi o ka ETFE, me ke ana wela hana o 89 K a hiki i 423 K (-185 °C a +150 °C a i ʻole −300 °F a +300 °F).[3]
Kūleʻa nā resins ETFE i ke kukui ultraviolet.ʻO ka hoʻāʻo ʻana i ka wā wikiwiki (e hoʻohālikelike ʻia me 30 mau makahiki o ka hoʻolaha ʻana) ʻaneʻane ʻaʻohe hōʻailona o ka pōʻino o ke kiʻiʻoniʻoni.
