I-Polytetrafluoroethylene (PTFE) yinto yokwenziwa eyasungulwa ngephutha ngasekupheleni kwawo-1930 ngenkathi usokhemisi ezama ukwakha uhlobo olusha lwesiqandisi esisekelwe ku-perfluorethylene.Kunokuba athole i-chlorofluorocarbon, usosayensi wamangala ukuthola ukuthi i-perfluorethylene esetshenziswe kule nqubo isabela ngokuqukethwe kwensimbi esitsheni sayo futhi yenziwa i-polymer ngaphansi kwengcindezi.Ngaphansi kweshumi leminyaka kamuva, le nto entsha yayisatshalaliswa ngezinga lezentengiso futhi yagcina inelungelo lobunikazi ngaphansi kwegama elithi polymer®.Kungaba eminye iminyaka engu-20 ngaphambi kokuba le nto ishaye epanini lokuthosa futhi yaziwe ngokuthi i-cookware yokuqala engelona induku ye-cookware.Eqinisweni, le nto yayisetshenziselwa ezinye izinjongo ezihlukahlukene ekuqaleni.
I-25% ye-carbon fiber egcwele.Ukumelana nokugqoka okuphezulu, ukumelana nomthwalo ophezulu, ukumelana nokugoba okuphezulu.
Izicelo: Isevisi yemishini (isb. ama-bearings, izigxivizo zemishini namaphedi okuthwala)
(1) I-anti-corrosion kuzo zonke izinhlobo zamakhemikhali okuhlanganisa i-nitric acid ne-aqua fortis.(2) Izici: Ukungqubuzana okuphansi, Cishe akukho mfuneko yokugcotshwa, Isisindo esilula, Imelana nokugqwala nokuhuzuka, Ingazweli, Izakhiwo zamakhemikhali ezizinzile, Ukumelana nowoyela, Ukumelana nokushisa okuphezulu, ukumelana nokushisa okuphansi, ukumelana namanzi nokunye.(3) izinga lokushisa lokusebenza:-55~+260°C.(4) Ukufakwa kukagesi;i-dielectric enhle ngama-mediums.(5) imikhiqizo yeshubhu ye-ptfe egcwalisiwe(ipayipi leshubhu lepulasitiki) Yenziwe nge-polytetrafluoroethylene resin exutshwa ngesivinini esikhulu kanye ne-resin ethile yokugcwalisa.
