Fluoroelastomer ikhoza kugawidwa m'njira zotsatirazi.
A. Kuchiritsa dongosolo
B. Ma Monomers
C. Mapulogalamu
Pamachiritso, pali njira ziwiri: Bisphenol kuchiritsikafkmndi peroxide yochiritsika fkm. Bishpenol curable fkm nthawi zambiri imakhala ndi mawonekedwe otsika a compression set, omwe amagwiritsidwa ntchito popanga magawo osindikiza monga ma orings, ma gaskets, mphete zosakhazikika, mbiri. Ndipo Peroxide curable fkm ili ndi kukana kwamankhwala kwabwinoko komanso makina amakina. Ili ndi kukana kwakukulu kwa nthunzi. Itha kugwiritsidwa ntchito muzovala zanzeru kapena batri ya Lithium.
Kwa ma monomers, pali copolymer yomwe imapangidwa ndi Vinylidene fluoride (VDF) ndi hexafluoropropylene (HFP); ndi terpolymer yomwe imapangidwa ndi Vinylidene fluoride (VDF), tetrafluoroethylene (TFE) ndi hexafluoropropylene (HFP). FKM copolymer ili ndi 66% ya fluorine yomwe ingagwiritsidwe ntchito ponseponse. Ngakhale fkm terpolymer ili ndi fluorine pafupifupi 68%, itha kugwiritsidwa ntchito m'malo ovuta omwe amafunikira kukana kwamankhwala / media.
Zofunsira, FUDI imapereka kuumba, kalendala, ma extrusion giredi fkm. Ndipo timaperekanso magiredi apadera monga kalasi yotsika yokana kutentha kwa GLT, zomwe zili ndi fluorine zambiri zokhala ndi fluorine 70%, kalasi ya nthunzi ndi alkali kukana FEPM Aflas, kalasi yabwino kwambiri yokana mankhwala perfluoroelastomer ffkm.
