FEP(Fluorinated ethylene propylene),Yi-copolymer ye-tetrafluoroethylene kunye ne-hexafluoropropylene.I-FEP inokufakwa kwiiplastiki ezithambileyo, kwaye amandla ayo okuqina, ukuxhathisa ukunxiba, ukuxhathisa kokunyuka kungaphantsi kuneeplastiki ezininzi zobunjineli, kwaye ine-dielectric ephantsi engaguqukiyo phezu kobushushu obubanzi kunye noluhlu lwamaza.
Izinto eziphathekayo azivuthi,it haveukuxhathisa okugqwesileyo kokunxiba kunye ne-coefficient ephantsi ye-friction.Ingenziwa kwiimveliso zegranular ze-extrusion kunye nokubumbakwayeisetyenziswe njengomgubo kwiibhedi ezimanzi kunye nokugqitywa kwe-electrostatic,Angokunjalounakoyenziwe yazii-aquaous dispersions .Iimveliso ezigqityiweyo zibandakanya iifilimu, iipleyiti, iintonga, i-electrode, iinxalenye ezikhethekileyo kunye nemicu enye.Mhayilyukusetyenziswa kukwenza umgca wangaphakathi wemibhobho kunye nezixhobo zekhemikhali, umgangatho ophezulu wee-roller kunye neengcingo ezahlukeneyo kunye neentambo.
