Chloroprene (Neoprene) Dry/Solid General Purpose | W Type Extrusion & Calendering

SND37

SND37 is an easy processing medium high viscosity solid chloroprene polymer. It is a better extrusion version of WXK with improved mold release. SND37 is designed for high loading compounding extrusion application with good die-swell and for complex mold goods with better mold release properties. 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.

WB

WB is an easy processing solid chloroprene polymer and it has the best extrusion and calendering properties. It contains no additives which affect the cure of other elastomers or contribute to the discolouration or staining of ordinary finishes. It is designed for general purpose use. It can be used alone or in combination with other chloroprene grades where exceptionally good performance in extrusion and calendering process is desired. Raw polymer stability is excellent. Excessive time and temperature of storage can cause an increase in viscosity.
