Viton B-601C Fluoroelastomer Dupont Dow Elastomers Fluoropolymer Soluble in low molecular weight esters and ketones Terpolymer of hexafluoropropylene, vinylidene fluoride and tetrafluoroethylene, plus cure chemicals Viton B-601C is an incorporated cure “B-family” polymer that demonstrates improved processing properties when compared to older “B-family” terpolymer fluoroelastomers. The improved properties provide excellent compound flow in molding (compression, injection, transfer) parts where the heat and fluid characteristics of a “B-family” Viton are needed. Compared with older “B-family” terpolymers, Viton B-601C provides: Fully precompounded O-ring curative level Improved processing better mixing excellent scorch safety better mold release with less mold fouling Medium to fast cure rate Improved compression set coatings Terpolymer of hexafluoropropylene, vinylidene fluoride, and tetrafluoroethylene, plus cure chemicals. Used in coatings. Offers improved processing properties, medium to fast cure rate and improved compression set.
