Fun eto imularada, awọn ọna meji gbogbogbo wa: Bisphenol curablefkmati peroxide curable fkm. Bishpenol curable fkm nigbagbogbo ni awọn ẹya ara ẹrọ ti ipilẹ funmorawon kekere, eyiti o lo fun didimu awọn apakan lilẹ bii orings, gaskets, awọn oruka alaibamu, awọn profaili. Ati pe fkm curable Peroxide ni resistance kemikali to dara julọ ati awọn ohun-ini ẹrọ. O ni o ni nla resistance to nya. O le ṣee lo ni smart wearables tabi batiri litiumu.
Fun awọn monomers, copolymer wa eyiti o jẹ nipasẹ Vinylidene fluoride (VDF) ati hexafluoropropylene (HFP); ati terpolymer eyiti o jẹ nipasẹ Vinylidene fluoride (VDF), tetrafluoroethylene (TFE) ati hexafluoropropylene (HFP). FKM copolymer ni 66% akoonu fluorine le ṣee lo ni ohun elo gbogbogbo. Lakoko ti fkm terpolymer ni akoonu fluorine nipa 68%, o le ṣee lo ni agbegbe lile ti o nilo kemikali to dara julọ / resistance media.
Fun awọn ohun elo, FUDI ipese igbáti, kalẹnda, extrusion onipò fkm. Ati pe a tun pese awọn onipò pataki bi iwọn kekere resistance GLT, akoonu fluorine giga pẹlu akoonu fluorine 70%, nya si ati ipele resistance alkali FEPM Aflas, ipele resistance kemikali to dara julọ perfluoroelastomer ffkm.
