Hoʻohana ʻia ʻo PTFE ma ke ʻano he inoa kālepa no kekahi mau polymers ʻē aʻe me ka haku mele like, e like me ka ethylene propylene (FEP) a me ka resin perfluoroalkoxy (PFA) Ua like nā waiwai o kēia mau polymers me nā ptfe.
ʻOi aku ka palupalu o ka FEPFEP ma mua o ka polymer a maopopo loa a kū i ka lā.ʻOi aku ka maikaʻi ma mua o ka polymer.He haʻahaʻa haʻahaʻa loa ia o ka friction a me ke kūpaʻa kiʻekiʻe i ka wela.Hiki ke hoʻohana ʻia no ka welding, heat-sealing, a me ka thermoforming.Hoʻohana ʻia ia i ka hoʻolālā a me ka hana ʻana i nā thermoplastics me nā hiʻohiʻona haʻahaʻa haʻahaʻa.Hoʻohana nui ʻia ka FEP nonstick coatings no ka uhi ʻana i nā ipu i hoʻohana ʻia i ka kuke ʻana.Aia ka FEP ma ke ʻano wai wai a me ka pauka.
e nana i na waiwai o FEP.
ʻAʻole hoʻokō ka PFAPFA ma ke ʻano a he haʻahaʻa haʻahaʻa o ka friction.Hoʻohana pū ʻia ʻo PFA no ka uhi ʻana i nā mea bake ʻoihana.Eia nō naʻe, ʻoi aku ka maikaʻi o nā hiʻohiʻona hana o ka PFA ma mua o ka FEP no ka mea hiki iā PFA ke kū i nā wela kiʻekiʻe no ka lōʻihi o ka manawa.Eia kekahi, ʻoi aku ka paʻakikī ma mua o ka FEP a me ka polymer.Aia ka PFA i ka pauka a me ka wai.
e nānā i nā waiwai o PFA.
ʻO Tefzel a i ʻole ETFEETFE he copolymer o ka ethylene a me ka tetrafluoroethylene.ʻO Tefzel kona inoa kālepa.ʻOkoʻa iki ke ʻano mole o ka ETFE mai ka polymer.I ka polymer, ua pani ʻia nā ʻātoma hydrogen a pau e ka fluorine aʻo ka ETFE, ua hoʻololi ʻia kahi helu liʻiliʻi o nā molekala hydrogen.
