Viton™ B-50 is a bisphenol (BPAF) cured gum fluoropolymer with low viscosity and improved mold flow compared to other B-type gum polymers. It is excellent for use in extruded goods, complicated moldings, and high-voltage insulation parts.
Viton™ B-50 fluoroelastomer is a B-type gum polymer composed of hexafluoropropylene (HFP), vinylidene fluoride (VF2), and tetrafluoroethylene (TFP) with 68.5% fluorine content.
Viton™ B-50 provides a higher viscosity level than other B-type gum polymers and is best suited for compression molding applications. Viton™ B-50 also resists fluids and retains flexibility better under dry heat than A-type polymers.
