FKM copolymer refers to Fluoroelastomer Copolymer FKM is a type of fluoroelastomer that consists primarily of a copolymer of polyvinylidene fluoride (VDF) and hexafluoropropylene (HFP). Compared to FKM terpolymer, FKM copolymer has only two monomers and generally exhibits good heat, oil and chemical resistance.
