Chloroprene (Neoprene) Dry/Solid General Purpose | W Type (Standard Group)

W – Standard Grade

W is a General Purpose grade supplied in dry chip form . W contains no additives which affect the cure of other elastomers or contribute to the discolouration or staining of ordinary finishes. Its raw polymer stability is excellent. It presents heat resistance and compression set resistance. It has industrial general purpose and extrusion applications and can also be used in adhesives. Excessive time and temperature of storage can cause an increase in viscosity.

WHV – Higher viscosity version of W

WHV is a high viscosity solid chloroprene grade suitable for high loading application and general adhesives. It is a higher viscosity version of W for high loading application and general adhesives. It contains no additives which affect the cure of other elastomers or contribute to the discolouration or staining of ordinary finishes. WHV is designed for use in highly extended stocks or for blends with other chloroprene products where increased polymer viscosity is needed for processing. It presents heat resistance and compression set resistance. The raw polymer stability of WHV is excellent. Excessive time and temperature of storage can cause an increase in viscosity.
