Описание материалов:
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.
