Chloroprene Rubber (CR) Additive Package
Chloroprene Rubber Additive Packages are tailored combinations of vulcanizing agents, accelerators, antioxidants, and processing aids specifically formulated for CR (neoprene) compounds. Typical systems include magnesium oxide and zinc oxide as acid acceptors and crosslinkers, combined with thiourea or ETU accelerators. These packages ensure optimal vulcanization, heat resistance, and chemical resistance of CR compounds.
