Viton B-651C
Fluoroelastomer
Dupont Dow Elastomers
含氟聚合物
Fluoropolymer
Soluble in low molecular weight esters and ketones
Terpolymer of hexafluoropropylene,
vinylidene
fluoride and
tetrafluoroethylene,
plus cure chemicals
and metal adhesion
promoter
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
coatings
Incorporated cure terpolymer of hexafluoropropylene, vinylidene fluoride, and tetrafluoroethylene, plus cure chemicals and metal adhesion promoter. Used in coatings. Offers improved processing properties and good metal bonding with standard industrial primers.
