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 processibility and/or improve flow. |
