Polytetrafluoroethylene (PTFE)yavumbuwe n’umuhanga mu bya shimi Dr Roy J. Plunkett muri Laboratoire ya Jackson ya DuPont i New Jersey mu 1938. Igihe yageragezaga gukora firigo nshya ya CFC, polytetrafluoroethylene polymerized mu cyombo kibika umuvuduko ukabije (icyuma ku rukuta rw’imbere rw’ubwo bwato cyahindutse icyombo umusemburo wa polymerisation reaction). Isosiyete ya DuPont yabonye ipatanti mu 1941 yandikisha ikirango cyayo ku izina rya “TEFLON” mu 1944. Nyuma, DuPont yatangiye ubucuruzi bwayo muri Teflon & reg; Usibye PTFE resin, twateje imbere ibicuruzwa, harimo na Teflon; AF (fluoropolymer amorphous), Teflon; FEP (fluorine etylene propylene resin), Teflon; FFR (fluoropolymer foam resin), Teflon; NXT (fluoropolymer resin), Teflon; PFA (perfluoroalkoxy resin) nibindi.

Umukandara wa Teflon

Ibicuruzwa by'ibi bikoresho muri rusange byitwa "gutwikira inkoni"; Nubwoko bwibikoresho bya polymer bikoresha fluor kugirango bisimbuze atome zose za hydrogen muri polyethylene. Ibi bikoresho bifite ibiranga aside irwanya, kurwanya alkali hamwe nudukoko twinshi kama, kandi ntibishobora gukemuka mumashanyarazi yose. Muri icyo gihe, polytetrafluoroethylene ifite ibiranga ubushyuhe bwo hejuru, kandi coefficente yayo yo guterana ni mike cyane, bityo irashobora gukoreshwa nk'amavuta, kandi ikanaba igifuniko cyiza kidafite isafuriya y'amavuta hamwe n'imbere y'amazi y'amazi.

Teflon irashobora gukoreshwa mumukandara wa convoyeur: Umukandara wa Teflon, umukandara wa Teflon, umukandara wuruhu ukonje, umukandara wa convoyeur, umukanda wa Teflon, umukandara wa PTFE, umukandara wa tapi, umwenda wumuryango, umukandara wibiryo, nibindi birumvikana, turashobora uyikoreshe kandi kuri kaseti: kaseti ya Teflon, kaseti ya Teflon ikirahure fibre yifata, kaseti ya Teflon yubushyuhe bwo hejuru, kaseti yifata, igitambaro cyo gusudira wenyine, n'ibindi.
