Chemours Viton® GBL-200S Fluoroelastomer Compound
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)
Material Notes:
  • Is ideal for blending with Viton® GBL-600S to reach intermediate viscosity ranges
  • Cures exceptionally fast to a high state of cure
  • Exhibits improved mold release/mold fouling properties compared to Viton® GBL-900 and Viton® GBL-200
  • Exhibits improved mold flow and less shear sensitivity than 65 Mooney Viton® GBL-600S
  • Exhibits excellent physical properties with high elongation, both original and aged compounds
  • Exhibits similar heat, fluids, and low temperature resistance compared to Viton® GBL-200
  • Exhibits excellent compression set resistance with little (2 hr) or no postcure either low or no postcure

Chemours was formed from former DuPont performance chemicals businesses, including the Viton product line, in 2015.
