Chemours Viton® GFLT-600S with Ca(OH)2 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 Similar to improved low temperature properties compared to Viton® GFLT Improved mold release/mold fouling properties Improved mold flow and less shear sensitivity for a 65 Mooney peroxy cured FKM Excellent physical properties with high elongation, both original and aged Heat, fluids, and low temperature resistance comparable to Viton® GFLT 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.
