Product Description
Viton® GLT-200S fluoroelastomer, formerly known as VTR-8505, is a 64% fluorine, peroxide-cured, low temperature fluoroelastomer similar to Viton® GLT-600S but with a significantly lower gum polymer viscosity of ~25 (ML at 121°C). GLT-200S utilizes the latest technology, Advanced Polymer Architecture (APA), which includes a novel peroxide cure site along with an optimized molecular weight distribution.

Features
  • 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 new GLT-600S
  • Improved water resistance/lower volume swell in water
  • Excellent compression set resistance with either low or no postcure
