I-PTFE isetshenziswa njengegama lokuhweba kwamanye ama-polymer ambalwa anokwakheka okufanayo, njenge-ethylene propylene (FEP) kanye ne-perfluoroalkoxy resin (PFA) Izici zalawa mapholymer ziyefana nalezo ze-ptfe.
I-FEPFEP ithambile kune-polymer futhi isobala kakhulu futhi imelana nokukhanya kwelanga.Iyakheka kakhulu kune-polymer.Ine-coefficient ephansi kakhulu yokungqubuzana kanye nokumelana okuphezulu nokushisa.Ingasetshenziselwa i-welding, i-heat-sealing, ne-thermoforming.Isetshenziswa ekwakhiweni nasekukhiqizeni ama-thermoplastic anezici eziphansi zokungqubuzana.I-FEP ye-nonstick coatings isetshenziswa kakhulu ukumbozwa kweziqukathi ezisetshenziswa ekubhakeni kwezimboni.I-FEP ikhona kokubili uketshezi olusekelwe emanzini kanye nefomu lempushana.
ukuze ubuke izakhiwo ze-FEP.
I-PFAPFA ayisebenzi ngokwemvelo futhi ine-coefficient ephansi yokungqubuzana.I-PFA iphinde isetshenziselwe ukumboza izinto zokubhaka ezimbonini.Kodwa-ke, izici zokusebenza ze-PFA zingcono kakhulu kunezo ze-FEP ngoba i-PFA ingakwazi ukumelana namazinga okushisa aphezulu isikhathi eside.Ngaphezu kwalokho, inokuqina okukhulu kunakho kokubili i-FEP ne-polymer.I-PFA ikhona ngempushana nefomu eliwuketshezi.
ukubuka izakhiwo ze-PFA.
I-Tefzel noma i-ETFEETFE iyi-copolymer ye-ethylene ne-tetrafluoroethylene.Igama layo lezentengiso yi-Tefzel.Isakhiwo samangqamuzana e-ETFE sihluke kancane kuleso se-polymer.Ku-polymer, wonke ama-athomu e-hydrogen athathelwa indawo yi-fluorine kuyilapho ku-ETFE, inani elincane lama-molecule e-hydrogen lishintshwa.
