I-Fluoroelastomer inokwahlulwa ngeendlela ezilandelayo.
A. Inkqubo yokunyanga
B. IiMonomers
C. Izicelo
Kwinkqubo yokunyanga, kukho iindlela ezimbini ngokubanzi: iBisphenol enyangekayofkmkunye neperoxide enyangekayo fkm. I-Bishpenol curable fkm idla ngokuba ngumnini weempawu zeseti yoxinzelelo oluphantsi, esetyenziselwa ukubumba iindawo zokutywina njenge-orings, iigaskets, imisesane engaqhelekanga, iiprofayili. Kwaye iPeroxide enyangekayo fkm inokumelana neekhemikhali ezingcono kunye neempawu zoomatshini. Inokumelana kakhulu nomphunga. Ingasetyenziswa kwizinto zokunxiba ezikrelekrele okanye ibhetri yeLithium.
Kwii-monomers, kukho i-copolymer eyenziwa yi-Vinylidene fluoride (VDF) kunye ne-hexafluoropropylene (HFP); kunye ne-terpolymer eyenziwe yiVinylidene fluoride (VDF), tetrafluoroethylene (TFE) kunye ne-hexafluoropropylene (HFP). I-copolymer ye-FKM ine-66% yomxholo we-fluorine enokusetyenziswa ngokubanzi. Ngelixa i-fkm terpolymer inomxholo wefluorine malunga ne-68%, inokusetyenziswa kwindawo erhabaxa efuna ukuxhathisa okungcono kweekhemikhali/kumajelo eendaba.
Kwizicelo, i-FUDI yokubonelela ngokubumba, ikhalenda, amabakala e-extrusion fkm. Kwaye sikwabonelela ngamabakala akhethekileyo afana nebakala elisezantsi lokumelana nobushushu beGLT, umxholo wefluorine ophezulu onomxholo wefluorine wama-70%, ibakala lokuxhathisa umphunga kunye nealkali ye-FEPM Aflas, ibakala eligqwesileyo lokuxhathisa imichiza perfluoroelastomer ffkm.
