Ethylene tetrafluoroethylene (ETFE) yog fluorine-based yas.Nws tau tsim los kom muaj kev tiv thaiv corrosion siab thiab muaj zog tshaj qhov kub thiab txias.ETFE yog ib qho polymer thiab nws lub npe raws li poly (ethene-co-tetrafluoroethene).ETFE muaj qhov kub siab melting kub, tshuaj zoo heev, hluav taws xob thiab hluav taws xob hluav taws xob tsis zoo.Thaum hlawv, ETFE tso tawm hydrofluoric acid.
Cov rooj sib piv muaj txiaj ntsig ntawm PTFE tiv thaiv FEP, PFA thiab ETFE tuaj yeem pom ntawm DuPont lub vev xaib, teev cov khoom siv hluav taws xob, thermal, tshuaj lom neeg, hluav taws xob, thiab vapor zog ntawm txhua tus, ib sab.
ETFE yog qhov ua tau zoo ntawm lub zog siab ntawm lwm qhov peb hauv pawg no, feem ntau muaj peev xwm txo qis me ntsis hauv lwm qhov chaw los ntawm kev sib piv.
Combustion ntawm ETFE tshwm sim ib yam li ib tug xov tooj ntawm lwm yam fluoropolymer, nyob rau hauv cov nqe lus ntawm tso hydrofluoric acid (HF).HF yog corrosive heev thiab lom, thiab yog li yuav tsum tau ceev faj kom tsim nyog.
ETFE zaj duab xis yog kev tu tus kheej (vim nws qhov chaw tsis muaj zog) thiab rov ua dua tshiab.Nws yooj yim rau punctures los ntawm cov npoo ntse thiab yog li feem ntau siv rau lub ru tsev.Raws li cov yeeb yaj kiab rau vov tsev nws tuaj yeem ncab (txog 3x) thiab tseem yuav taut yog tias muaj qee qhov kev hloov pauv loj tshwm sim (vim kev nthuav dav thermal, piv txwv li.) Ua haujlwm kub vuam, lub kua muag tuaj yeem kho nrog ib daim ntaub lossis ntau daim ntawv sib sau ua ke. cov vaj huam sib luag loj dua.
ETFE muaj lub zog tensile kwv yees ntawm 42 MPa (6100 psi), nrog rau kev ua haujlwm kub ntawm 89 K txog 423 K (−185 ° C txog + 150 ° C lossis −300 ° F txog + 300 ° F).[3]
ETFE resins yog resistant rau ultraviolet lub teeb.Kev ntsuas huab cua nrawm (piv rau 30 xyoo raug) ua rau yuav luag tsis muaj cov tsos mob ntawm cov yeeb yaj kiab deterioration.
