Viton A-401C
Fluoroelastomer
Dupont Dow Elastomers
含氟聚合物
Fluoropolymer
Soluble in low molecular weight esters and ketones
Dipolymer of hexafluoropropylene and vinylidene fluoride, plus cure chemicals
Viton A-401C fluoroelastomer is an incorporated
cure “A-family” dipolymer designed for compression
molding of sealing devices that must meet major
fluoroelastomer specifications. In addition to the heat
and chemical resistance characteristics typical of
Viton fluoroelastomers, Viton A-401C offers significant
improvements in processing and rheology. Viton
A-401C can be blended with similar Viton types to
provide variations in processing, properties, and
shrinkage.
Compared with Viton E-60C, Viton A-401C features:
Fully precompounded
O-ring curative level
Improved compression molding
increased mold flow
easier mold release
less mold fouling
Improved extrusion
Increased cure rate
Improved compression set resistance
Same mold shrinkage as Viton E-60C
coatings
