PTFEndi fluoropolymer yofewa, yopanda poizoni yokhala ndi coefficient yotsika kwambiri, kutanthauza kuti zida zochepa zimamamatira, ndipo zambiri zomwe zimamatira zimatha kusenda kapena kupukuta.PTFE ilinso ndi mankhwala komanso kukana kwanyengo.PTFE ndi insoluble zambiri organics ndipo ali kwambiri magetsi katundu.Imakhalabe yokhazikika pa kutentha kwa cryogenic komanso kokwera (kuchokera -400 ° F mpaka 500 ° F), ngakhale kuti makina ake ndi otsika poyerekeza ndi mapulasitiki ena a engineering.Makina, magetsi ndi matenthedwe a PTFE amatha kuwongolera powonjezera zodzaza monga magalasi, mpweya, graphite, bronze ndi molybdenum disulfide (MoS2).Zomwe zimagwiritsidwa ntchito zimaphatikizapo zisindikizo, ma bearings, bushings, zolekanitsa ma coil, ma terminals, ndi mapaipi olimba ndi zolumikizira.
PTFE ndikufotokozera kwa mankhwala a polytetrafluoroethylene, kapena odziwika bwino ngati polima ya DuPont.Otsatsa ena ambiri amapanganso PTFE grannular ndi utomoni waulere.
TFE ndi dzina lamankhwala la tetrafluoroethylene, lomwe ndi mpweya wopanda utoto komanso wopanda tase, wapoizoni kwambiri komanso wakupha.
Osasokoneza ziwirizi, ngakhale makampani opanga mapulasitiki agwiritsa ntchito molakwika mawuwa pazaka zambiri.
TFE ndiye kalambulabwalo monomer yopanga PTFE.Chifukwa chake ndikuganiza kuti sanavutike ndi 'P'.FEP ndi PFA ndi mitundu ina iwiri yodziwika bwino ya polima.Iwo amasungunuka processable pamene PTFE si.Zosintha zonse zimakhala zovuta kulumikizana nazo.Njira zomwe zimagwiritsidwa ntchito kuti zigwirizane ndizomwe zimapangidwira (mwina zomwe mukuyesera), plasma pre-etching, corona treatments, etc..
Mutha kuwonanso zinthu zathu za PTFE (ptfe ndodo, ptfe chubu, chubu ndi payipi) kwa zitsanzo zaulere.
