PTFE inoshandiswa sezita rekutengesa kune mamwe mashoma mapolymer ane chimiro chakafanana, senge ethylene propylene (FEP) uye perfluoroalkoxy resin (PFA) Zvimiro zvemapolymers aya akafanana neaya eptfe.
FEPFEP yakapfava kupfuura polima uye iri pachena uye inoshingirira kuchiedza chezuva.Iyo yakanyanya kuumbwa kupfuura polymer.Iyo ine yakanyanya kuderera coefficient ye friction uye yakakwirira kuramba kupisa.Inogona kushandiswa kugadzira, kupisa-kuisa chisimbiso, uye thermoforming.Inoshandiswa mukugadzira uye kugadzira thermoplastics ine yakaderera frictional maitiro.FEP nonstick coatings anonyanya kushandiswa kupfekedza midziyo inoshandiswa mukubika maindasitiri.FEP iripo mune zvese zviri mumvura-based liquid fomu uye fomu yehupfu.
kuona zvimiro zveFEP.
PFAPFA haishande muchisikigo uye ine yakaderera coefficient yekupokana.PFA inoshandiswawo kuvhara mabikirwo ezvigadzirwa zveindasitiri.Nekudaro, maitiro ekuita ePFA ari nani kupfuura ayo eFEP nekuti PFA inokwanisa kumira tembiricha yakanyanya kwenguva yakareba.Mukuwedzera, ine kuoma kukuru kupfuura zvese FEP uye polymer.PFA iripo muhupfu uye fomu yemvura.
kuona zvimiro zvePFA.
Tefzel kana ETFEETFE icopolymer ye ethylene uye tetrafluoroethylene.Iro zita rekutengesa ndiro Tefzel.Iyo molecular chimiro cheETFE chakasiyana zvishoma neiyo yepolymer.Mupolymer, maatomu ese ehydrogen anotsiviwa nefluorine asi muETFE, nhamba diki yehydrogen mamorekuru inotsiviwa.
