FKM Fluoroelastomer Rubber Precompound 20-60 Mooney Viscosity
Fluoroelastomers (FKM) are synthetic rubber materials offering exceptional resistance to heat, chemicals, fuels, oils, solvents, and extreme environments. As part of the fluoropolymer family, they combine high-temperature stability, chemical inertness, and superior mechanical properties.
FKMs consist of a base polymer, typically vinylidene-fluoride (VDF) and hexa-fluoropropylene (HFP), copolymerized with other monomers to achieve specific characteristics. The material's highly saturated fluorinated backbone provides outstanding resistance to heat and chemical degradation.
