FKM ORingKlasifikasyon FKM la baze sou kontni fliyò oswa mekanis yo nan retikulasyon, osi byen ke konpozisyon chimik yo. Rezistans a pwodwi chimik yo ak chalè se yon karakteristik te ajoute nan FKMs. Konpayi ki pwodwi FKMs gen ladan Dyneon Fluoroelastomers (3M), HaloPolymer (Elaftor) Solvay Polymers espesyalite, Daikin Chimik kòm byen ke yon kantite manifaktirè ki soti nan Lachin. Pri a nan Flooroelastomers se pi wo pase sa yo ki an kawotchou nitrile oswa neoprene.
