Chemours Viton® B-202 Fluoroelastomer (FKM)
Categories: Polymer; Thermoset; Fluoropolymer, TS; Thermoset Fluoroelastomer; Rubber or Thermoset Elastomer (TSE)

Material Notes: Description: Viton® B-202 is a low viscosity, B-type gum polymer that demonstrates improved processing and rheology when compared with existing fluoroelastomers. Viton® B-202 is designed to be cured with either Viton® Curative #30 or Viton® Curative #50. When using Viton® Curative #30, use Viton® Curative #20 in a ratio of about 1.8 Viton® Curative #30 to Viton® Curative #20. When using Viton® Curative #50, use 0.3–0.5 phr of Viton® Curative #20 to ensure a fast cure rate. Note that Viton® Curative #20 can be difficult to mix into low viscosity stocks, such as those based on Viton® B-202, and careful attention needs to be paid to mixing procedures. Compared with other B-family terpolymers, Viton® B-202 provides:
  • Low viscosity
  • Improved processing
  • Increased mold flow
  • Excellent mold release

Applications:

  • Transfer and injection molding of complex shapes
  • Extrusions (e.g., fuel hose and tubing)
  • Solution coatings of fabrics, tanks or chemical containers

Viton® B-202 can be blended with other Viton® types to modify viscosity, enhance processability and/or improve flow.

Information provided by manufacturer.

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