Chemours Viton® GLT-200S Fluoroelastomer Compound
Categories:	Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:	Cures exceptionally fast to a high state of cure Is ideal for blending with Viton® GLT-600S to reach intermediate viscosity ranges for injection molding Improved mold release/mold fouling properties Improved mold flow and less shear sensitivity than 65 Mooney Viton® GLT-600S Excellent physical properties with high elongation, both original and aged Heat, fluids, and low temperature resistance comparable to Viton® GLT and GLT-600S Improved water resistance/lower volume swell in water Excellent compression set resistance with either low or no postcure Chemours was formed from former DuPont performance chemicals businesses, including the Viton product line, in 2015.
