Chemours Viton® A-361C with 45 MT Black Fluoroelastomer Compound
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)

Material Notes:
  • Intermediate viscosity level (when compared with Viton® A-201C/Viton® A-401C)
  • Fully precompounded with reduced curative level and Incorporated metal adhesion promoter
  • Improved processing with increased mold flow, easier mold release with less mold fouling, and improved demolding “hot tear”
  • Good metal bonding with standard industrial primers

Applications

  • Compression, transfer, and injection molding of: O-rings and gaskets, Valve stem and crankshaft seals (and other bonded parts requiring fluid and heat resistance of the A-family of Viton®)

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