FEP(Fluorinated ethylene propylene),He copolymer o ka tetrafluoroethylene a me ka hexafluoropropylene.Hiki ke hoʻohana ʻia ka FEP i nā plastik palupalu, a ʻoi aku ka haʻahaʻa o kona ikaika tensile, ʻaʻahu i ke kūpaʻa, ʻoi aku ka haʻahaʻa o ke kūpaʻa ʻana ma mua o ka nui o nā plastics engineering, a he haʻahaʻa haʻahaʻa haʻahaʻa ma luna o kahi ākea ākea a me ke alapine.
ʻAʻole ʻā ka mea,it haveʻoi aku ka maikaʻi o ka hoʻohana ʻana a me ke koena haʻahaʻa o ka friction.Hiki ke hana ʻia i nā huahana granular no ka extrusion a me ka hoʻoheheʻe ʻanaahoʻohana ʻia e like me nā pauka no nā moena wai a me ka hoʻopau electrostatic,Alsohikihana ʻia i hoʻopuehu wai .ʻO nā huahana semi-finished nā kiʻiʻoniʻoni, nā papa, nā koʻokoʻo, nā electrodes, nā ʻāpana kūikawā a me nā fibers hoʻokahi.MainlyʻO ka hoʻohana ʻana i ka hana ʻana i ka uhi o loko o nā paipu a me nā mea hana kemika, ka ʻili o nā wili a me nā uea like ʻole a me nā kaula.
