| Viton® GFLT-200S fluoroelastomer is a low viscosity 67% fluorine, peroxide-cured, low temperature fluoroelastomer. GFLT-200S utilizes the latest technology, Advanced Polymer Architecture (APA), which includes a novel peroxide cure site along with an optimized molecular weight distribution. Features Is ideal for blending with Viton® GFLT-600S to reach intermediate viscosity ranges for injection and transfer molding Heat, fluids, and low temperature resistance comparable to Viton® GFLT-300 and GFLT-301 Cures exceptionally fast to a high state of cure Improved mold release/mold fouling properties Improved mold flow and less shear sensitivity for a 25 Mooney peroxy cured FKM Good physical properties with high elongation, both original and aged Improved water resistance/lower volume swell in water Excellent compression set resistance with either low or no postcure&& |
