I-Polytetrafluoroethylene (PTFE)yatholwa usokhemisi uDkt Roy J. Plunkett eJackson Laboratory yaseDuPont eNew Jersey ngo-1938. Lapho ezama ukwenza isiqandisi esisha se-CFC, i-polytetrafluoroethylene eyenziwe nge-polymerized emkhunjini wokugcina umfutho ophezulu (insimbi esodongeni lwangaphakathi lomkhumbi yaba i-catalyst ye-polymerization reaction). Inkampani yaseDuPont yathola ilungelo layo lobunikazi ngo-1941 futhi yabhalisa uphawu lwayo lokuthengisa ngaphansi kwegama elithi “TEFLON” ngo-1944. Kamuva, iDuPont yaqala ibhizinisi layo eTeflon & reg; Ngaphezu PTFE resin, siye sakha uchungechunge imikhiqizo, kuhlanganise Teflon; I-AF (i-amorphous fluoropolymer), i-Teflon; I-FEP (i-fluorinated ethylene propylene resin), i-Teflon; I-FFR (i-fluoropolymer foam resin), i-Teflon; I-NXT (i-fluoropolymer resin), i-Teflon; PFA (perfluoroalkoxy resin) nokunye.

Imikhiqizo yalokhu kwaziswa ngokuvamile ibizwa ngokuthi “i-non stick coating”; Iwuhlobo lwezinto zokwenziwa ze-polymer ezisebenzisa i-fluorine ukufaka esikhundleni sawo wonke ama-athomu e-hydrogen ku-polyethylene. Le nto inezici zokumelana ne-asidi, ukumelana ne-alkali kanye nezincibilikisi ezihlukahlukene eziphilayo, futhi cishe ayincibiliki kuzo zonke izincibilikisi. Ngesikhathi esifanayo, i-polytetrafluoroethylene inezici zokumelana nokushisa okuphezulu, futhi i-coefficient yayo ye-friction iphansi kakhulu, ngakho-ke ingasetshenziswa njenge-lubrication, futhi ibe ukugqoka okuhle ngaphandle kwe-pan kawoyela kanye nongqimba lwangaphakathi lwepayipi lamanzi.

I-Teflon ingasetshenziswa ebhandeni lokuthutha: Ibhande le-Teflon lokuthutha, ibhande le-Teflon lokuthutha, ibhande lokuhambisa isikhumba esibandayo, ibhande lokuhambisa amapayipi, indwangu ye-Teflon, ibhande lendwangu ye-PTFE, ibhande lokhaphethi, indwangu yomnyango, ibhande lokuhambisa ukudla, njll. Yiqiniso, singakwazi futhi uyisebenzise ku-tape: i-Teflon adhesive tape, i-Teflon glass fiber adhesive itheyiphu, itheyiphu ye-Teflon ukumelana nokushisa okuphezulu, iteyiphu yokunamathela, indwangu yokushisela enamathelayo, njll.
