PTFE-polytetrafluoroethylene bụ onye Dr. Roy Plunkett nke DuPont Research Laboratory chọpụtara na Eprel 6, 1938. PTFE mbụ bụ nke Dupont mepụtara ma wepụta ya dị ka ngwaahịa na 1945.

Ngwaahịa a na-eguzogide ọgwụ corrosion nke kemịkalụ ma nwee ike ijikwa okpomọkụ karịrị 500 Celsius C. Otu n'ime ihe mbụ ụlọ PTFE bụ "PTFE mkpuchi frying pan".Ọ bụ ezie na ite ahụ na-arụ ọrụ nke ọma, ọ dị iche na mkpanaka PTFE na efere anyị na-ebunye.Ọ bụ sprayed na fọrọ nke nta nwa mkpuchi, dị ọcha PTFE mkpara na Ibé akwụkwọ na PTFE gburugburu mmanya uzuoku valvụ ngwugwu bụ na-egbuke egbuke na-acha ọcha otú e si eji ulo oru PTFE plastic mkpara otú iji ulo oru PTFE plastic mkpara PTFE gaskets na uzuoku nkwakọ.

N'ihi na PTFE nwere oke okpomọkụ na nguzogide kemịkalụ, a na-ejikarị ya eme ihe maka ngwa valve.Site na valvụ uzuoku / mmiri ọkụ dị mfe ruo na oke okpomọkụ, ụlọ ọrụ na-ahụ maka mmiri mmiri na-akpata valves kemịkalụ.Ihe a na-esighi ike ruo rọba siri ike ma nwee ike ịme ya ngwa ngwa - otu n'ime ihe kachasị mfe iji plastik.The PTFE mkpanaka nwere ike machined n'ime nnọọ nso tolerances na ọtụtụ obere dayameta mkpara na a dayameta nke + .002 "/ - .00".Nguzogide kemịkalụ bụ otu n'ime ihe ndị bụ isi ejikọtara na ihe.Na flakes ma ọ bụ flakes, PTFE na-eji dị ka gasket ihe maka elu okpomọkụ na chemical na-eguzogide flanges na akàrà.
