Neoprene WHV polychloroprene rubber Dupont Dow Elastomers Rubber - Elastomer >> Chlorinated rubber / Chloroprene, CR ADHESIVE Adhesives: High pressure laminate Non-staining, general-purpose polychloroprene. Neoprene WHV synthetic rubber does not decrease in molecular weight, either under mechanical shear or with chemical peptization. However, some reduction in viscosity may occur under high shear condition. Compounds of Neoprene WHV mix rapidly, develop few heat during mixing, have good mill release, and yield extrudates that are resistant to distortion. possible to accommodate virtually any desired loading of fillers and plasticizers while still maintaining workable compound viscosity. Because cure accelerators must be used to achieve practical cure rates, processing safety and cure rate can be varied to suit processing requirements. Neoprene WHV can be compounded to provide the best resistance to heat aging and lowest compression set possible with Neoprene. Non-staining, polychloroprene synthetic rubber. Does not decrease in molecular weight. Some reduction in viscosity may occur under high shear condition. Provides rapid mix, few heat during mixing, good mill release and extrudates that are resistant to distortion.
