FEP(Fluorine etylene propylene),Ni copolymer ya tetrafluoroethylene na hexafluoropropylene.FEP irashobora gukoreshwa kuri plastiki yoroshye, kandi imbaraga zayo zikaze, kwambara birwanya, kurwanya ibinyabuzima bigenda munsi ya plastiki yubuhanga, kandi ifite dielectric ihoraho hejuru yubushyuhe bwagutse nubunini bwinshyi.
Ibikoresho ntibitwika,it haveimyambarire myiza yo kwambara hamwe na coefficient nkeya yo guterana.Irashobora gukorwa mubicuruzwa bya granulaire yo gukuramo no kubumbanaikoreshwa nka poro kuburiri bwamazi no kurangiza electrostatike,Alsoirashoborabikozwe mu mazi.Ibicuruzwa byarangiye birimo firime, amasahani, inkoni, electrode, ibice byihariye-na fibre imwe.Mainlyikoreshwa nugukora umurongo wimbere wibikoresho nibikoresho bya chimique, hejuru yuburinganire bwimigozi ninsinga zitandukanye ninsinga.
