Viton™ B-651C* is an incorporated cure “B-family” terpolymer that demonstrates improved processing properties and better metal adhesion when compared with older “B-family” terpolymer fluoroelastomers. The improved properties provide excellent compound flow in molding (injection, transfer, compression) bonded parts where the heat and fluid characteristics of a “B-family” Viton™ are needed.
Compared with older ”B-family” terpolymers, Viton™ B-651C features:
• Fully precompounded with curative and metal adhesion promoter
• Improved processing
– Better mixing
– Increased mold flow
– Easier mold release with less mold fouling
– Better 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 terpolymer characteristics)
• Complex-shaped parts
