Viton™ A-HV is a gum fluoropolymer with an ultrahigh viscosity supplied in sheet form. Viton™ A-HV provides the best resistance to compression set compared to other A-type polymers.
Viton™ A-HV fluoroelastomers (FKM) are A-type gum polymers composed of hexafluoropropylene (HFP) and vinylidene fluoride (VF₂). Viton™ A-HV contains 66% fluorine content and offers the highest among all A-type polymers. Viton™ A-HV provides excellent tensile strength and compression set resistance. Viton™ A-HV can be cured with both bisphenol AF and amine-type curatives.
