Fluoroelastomer ingagawidwe m'njira zotsatirazi.
A. Njira yophikira
B. Ma monomers
C. Mapulogalamu
Pa njira yochiritsira, pali njira ziwiri zazikulu: Bisphenol yochiritsikafkmndi peroxide yochiritsika fkm. Bishpenol yochiritsika fkm nthawi zambiri imakhala ndi mawonekedwe a seti yocheperako yopanikizika, yomwe imagwiritsidwa ntchito popanga zinthu zotsekera monga ma orings, ma gaskets, mphete zosasinthasintha, ndi ma profiles. Ndipo Peroxide yochiritsika fkm ili ndi kukana kwabwino kwa mankhwala komanso mphamvu zamakanika. Ili ndi kukana kwakukulu ku nthunzi. Itha kugwiritsidwa ntchito mu zovala zanzeru kapena batri ya Lithium.
Pa 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 nthawi zambiri. Ngakhale fkm terpolymer ili ndi fluorine pafupifupi 68%, ingagwiritsidwe ntchito m'malo ovuta omwe amafunika kukana bwino mankhwala/media.
Pa ntchito, FUDI imapereka mawonekedwe, kalendala, ndi magiredi otulutsa fkm. Ndipo timaperekanso magiredi apadera monga kalasi yotsika ya GLT yokana kutentha, kuchuluka kwa fluorine yokhala ndi 70% ya fluorine, kalasi yotsutsa nthunzi ndi alkali ya FEPM Aflas, perfluoroelastomer yabwino kwambiri yokana mankhwala ffkm.

FUDI yofanana ndi giredi ya FKM

| FD2614 | A401C | G-723 (701, 702, 716) | Tecnoflon® YA 80HS | Mooney Viscosity pafupifupi 40, fluorine ili ndi 66%, copolymer yopangidwira kupondereza. Yolimbikitsidwa kwambiri pa ma O-rings, ma gaskets. |
| FD2617P | A361C | G-752 | Tecnoflon® YA 5312K | Mooney Viscosity pafupifupi 40, fluorine ili ndi 66%, copolymer yopangidwira kukanikiza, kusamutsa ndi kuumba jakisoni. Yolimbikitsidwa kwambiri pa zomatira zamafuta. Kapangidwe kabwino kogwirizanitsa ndi zitsulo. |
| FD2611 | A201C | G-783, G-763 | Tecnoflon® YA 432 | Mooney Viscosity pafupifupi 25, fluorine ili ndi 66%, copolymer yopangidwira kupondereza ndi kuumba jakisoni. Yabwino kwambiri pa ma O-rings ndi ma gasket. Kuyenda bwino kwa nkhungu ndi kutulutsa nkhungu. |
| FD2611B | B201C | G-755, G-558 | Mooney Viscosity pafupifupi 30, fluorine ili ndi 67%, teopolymer yopangidwira kutulutsa. Yovomerezeka kwambiri pa payipi yamafuta ndi payipi yodzaza khosi. |
