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.
