Viton A-331C Fluoroelastomer Dupont Dow Elastomers Fluoropolymer Soluble in low molecular weight esters and ketones Dipolymer of hexafluoropropylene, and vinylidene fluoride plus cure chemicals and process aid Viton A-331C is an incorporated cure dipolymer designed for the injection and transfer molding of parts requiring improved demolding hot tear resistance. The moderate viscosity level of Viton A-331C also allows for satisfactory compression molding of parts. Features of Viton A-331C are: Intermediate viscosity level (when compared with related “O-ring” polymers Viton A-202C/Viton A-402C) Fully precompounded reduced curative level incorporated process aid Improved processing increased mold flow better mold release with less mold fouling improved demolding “hot tear” Good compression set resistance Dipolymer of hexafluoropropylene and vinylidene fluoride, plus cure chemicals and processing aids. Used in coatings. Offers moderate viscosity level, improved processing, increased mold flow and good compression set resistance.
