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
