Fluoroelastomer waxaa loo qaybin karaa siyaabaha soo socda.
A. Nidaamka daawaynta
B. Monomers
C. Codsiyada
Habka daaweynta Bisphenol waxaa loo isticmaali karaa laba siyaabood:fkmiyo fkm oo la daweyn karo oo peroxide ah. Bishpenol fkm oo la daweyn karo badanaa waxay leedahay sifooyinka qalabka cadaadiska hooseeya, kaas oo loo isticmaalo qaabaynta qaybaha shaabadaynta sida qalabka, gaskets-ka, giraanta aan caadiga ahayn, profiles-ka. FKM-ka la daweyn karo ee Peroxide-ka leh wuxuu leeyahay iska caabin kiimiko oo ka wanaagsan iyo sifooyin farsamo. Waxay leedahay iska caabin weyn oo uumi ah. Waxaa loo isticmaali karaa qalabka casriga ah ee la xidho ama baytariga Lithium.
Monomers-ka, waxaa jira copolymer-ka oo laga sameeyay Vinylidene fluoride (VDF) iyo hexafluoropropylene (HFP); iyo terpolymer-ka oo laga sameeyay Vinylidene fluoride (VDF), tetrafluoroethylene (TFE) iyo hexafluoropropylene (HFP). FKM copolymer-ku wuxuu leeyahay 66% fluorine oo loo isticmaali karo guud ahaan. In kasta oo fkm terpolymer-ku uu leeyahay fluorine qiyaastii 68%, waxaa loo isticmaali karaa jawi adag oo u baahan iska caabin kiimiko/dhexdhexaad wanaagsan.
Codsiyada, FUDI waxay bixisaa qaabaynta, jadwalka, iyo darajooyinka extrusion fkm. Waxaan sidoo kale bixinnaa darajooyin gaar ah sida heerka iska caabbinta heerkulka hooseeya ee GLT, maaddada fluorine oo sareysa oo leh maaddada fluorine 70%, heerka iska caabbinta uumiga iyo alkali ee FEPM Aflas, heerka iska caabbinta kiimikada ee perfluoroelastomer ffkm oo aad u fiican.
