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.
