Overview
Viton™ B-202 is a B-type fluoroelastomer gum composed of hexafluoropropylene (HFP), vinylidene fluoride (VF2), and tetrafluoroethylene (TFP).
Viton™ B-202 has 68.5% fluorine content and is best suited for extrusion applications when a low viscosity is required. Viton™ B-202 also offers lower MeOH permeability than Viton™ A-type fluoropolymers.
