Viton™ B-600* fluoroelastomer is a gum polymer that demonstrates improved terpolymer processing and lower compound viscosity, along with the excellent heat and fluid resistance characteristics of the “B-family” of Viton™. Viton™ B-600 is especially suited to curing with the bisphenol system: Viton™ Curative No. 20 and No. 30 or Viton™ Curative No. 50.
Compared with Viton™ B, Viton™ B-600 provides:
• Improved compression molding
– Increased mold flow
– Easier mold release
• Improved extrusion and calendering
• Increased cure rate
• Improved compression set resistance
Applications
Viton™ B-600 is highly recommended for applications, such as:
• Molded goods, e.g., shaft seals
• Calendered goods, e.g., flue duct expansion joints
Use of Viton™ B-600
Table 1 contains information comparing compounds of Viton™ B-600 and Viton™ B. Compound A is cured with Viton™ Curative No. 50 (for better de-molding), and Compound B with Viton™ Curative No. 20 and No. 30. VPA No. 3 processing aid is recommended for best de-molding. A study that compares the effect of carbon black level of Viton™ B-600 is shown in Table 2.
