Chloroprene (Neoprene) Dry/Solid General Purpose | W Type Low Mold Fouling

SND35

SND35 is a medium high viscosity solid chloroprene polymer with superior crystallization resistance and whose compounds show less mold fouling.  SND35 shows more excellent low temperature properties of WRT with improved mold release for injection molding goods. It is primarily designed for injection molding goods applications. It contains no additives which affect the cure of other elastomers or contribute to the discolouration or staining of ordinary finishes.Raw polymer stability is excellent. Excessive time and temperature of storage can cause an increase in viscosity.
