Ethylene tetrafluoroethylene (ETFE) waa balaastiig ku salaysan fluorine.Waxaa loo qaabeeyey inay lahaato iska caabin daxalka sare leh iyo xoogga heerkul ballaadhan oo ballaadhan.ETFE waa polymer oo magaceedu ku salaysan yahay poly(ethene-co-tetrafluoroethene).ETFE waxay leedahay heerkul dhalaal oo aad u sarreeya, kiimiko aad u wanaagsan, koronto iyo siyaalo iska caabbinta shucaaca tamarta sare leh.Marka la gubo, ETFE waxay sii deysaa hydrofluoric acid.
Jadwalka isbarbardhigga faa'iidada leh ee PTFE ee ka dhanka ah FEP, PFA iyo ETFE waxaa laga heli karaa bogga DuPont, oo taxaya qalabka farsamada, kulaylka, kiimikooyinka, korantada, iyo uumiga mid kasta, dhinac dhinac ah.
ETFE ayaa si wax ku ool ah u ah nooca xoogga badan ee saddexda kale ee kooxdan, oo inta badan muujisa awoodo yar yar oo dhinacyada kale ah marka la barbardhigo.
Gubashada ETFE waxay u dhacdaa si la mid ah tiro ka mid ah fluoropolymers kale, marka la eego sii deynta hydrofluoric acid (HF).HF aad bay u daxalaysaa waana sun, markaa waa in taxaddar ku habboon la sameeyaa.
Filimka ETFE waa is-nadiifinta (sabato ah oogada aan dhegta lahayn) oo dib loo warshadayn karo.Waxay u nugul tahay daloolada cidhifyada fiiqan oo sidaas darteed inta badan loo isticmaalo saqafka.Filim ahaan saqaf ahaan waa la fidin karaa (ilaa 3x) oo weli waa la taabsan karaa haddii cabbirka kala duwanaanshiyaha uu dhaco (sabato balaarinta kulaylka, tusaale ahaan) baalal waaweyn.
ETFE waxay leedahay quwad xajin ah oo qiyaas ah 42 MPa (6100 psi), oo leh heerkul shaqo oo kala duwan oo ah 89 K ilaa 423 K (-185 °C ilaa +150 °C ama -300 °F ilaa +300 °F).[3]
Xabagta ETFE waxay u adkaysataa iftiinka ultraviolet.Tijaabada cimilada ee la dedejiyey (marka la barbar dhigo 30 sano soo-gaadhista) ma aysan soo saarin ku dhawaad calaamado muujinaya xumaanta filimaanta.
