Polytetrafluoroethylene (PTFE)Masanin kimiyya Dr Roy J. Plunkett ne ya gano shi a dakin gwaje-gwaje na Jackson na DuPont a New Jersey a cikin 1938. Lokacin da ya yi ƙoƙarin yin sabon refrigerant na CFC, polytetrafluoroethylene polymerized a cikin wani babban ma'aunin ajiyar ruwa (ƙarfe a bangon ciki na jirgin ya zama mai kara kuzari don amsawar polymerization). Kamfanin DuPont ya sami haƙƙin mallaka a cikin 1941 kuma ya yi rajistar alamar kasuwanci a ƙarƙashin sunan "TEFLON" a cikin 1944. Daga baya, DuPont ya fara kasuwancinsa a Teflon & reg; Baya ga resin PTFE, mun haɓaka samfuran samfuran, gami da Teflon; AF (amorphous fluoropolymer), Teflon; FEP (resin ethylene propylene mai fluorinated), Teflon; FFR (fluoropolymer foam resin), Teflon; NXT (resin fluoropolymer), Teflon; PFA (perfluoroalkoxy resin) da sauransu.

Ana kiran samfuran wannan kayan gabaɗaya a matsayin "rufin da ba sanda ba"; Wani nau'i ne na kayan polymer na roba wanda ke amfani da fluorine don maye gurbin duk kwayoyin hydrogen a cikin polyethylene. Wannan abu yana da halayen juriya na acid, juriya na alkali da nau'ikan kaushi na kwayoyin halitta, kuma kusan kusan ba zai iya narkewa a cikin duk kaushi. A lokaci guda, polytetrafluoroethylene yana da halaye na tsayin daka na zafin jiki, kuma ƙarancin juzu'in sa yana da ƙasa sosai, don haka ana iya amfani da shi azaman lubrication, kuma ya zama madaidaicin shafi ba tare da kwanon mai ba da madaidaicin bututun ruwa.

Ana iya amfani da Teflon a cikin bel mai ɗaukar nauyi: Teflon mai ɗaukar bel, Teflon mai ɗaukar bel, bel mai sanyi na fata, bututun mai ɗaukar bel, Teflon zane, bel ɗin zane na PTFE, bel ɗin kafet, zanen kofa, bel mai ɗaukar abinci, da dai sauransu. Hakika, za mu iya. Har ila yau amfani da shi a kan tef: Teflon m tef, Teflon gilashin fiber m tef, Teflon high zafin jiki resistant tef, kai m tef, kai m waldi zane, da dai sauransu.
