Viton™ F-type precompounds are cured fluoroelastomer terpolymers composed of vinylidene fluoride (VF₂), hexafluoropropylene (HFP), and tetrafluoroethylene (TFE) monomers. F-type precompounds are engineered for high-performance sealing applications and contain 69.5% fluorine, which delivers exceptional chemical resistance, particularly against fuels, oils, and aggressive automotive fluids. Viton™ F-type precompounds are ready for direct use in compression molding and transfer molding processes and simplify manufacturing while ensuring consistent thermal stability, low permeability, and durability in harsh environments. Their advanced formulation makes them ideal for producing fuel system seals, gaskets, and O-rings used in automotive, aerospace, and industrial applications.
