Neoprene WB polychloroprene rubber Dupont Dow Elastomers Rubber - Elastomer >> Chlorinated rubber / Chloroprene, CR ADHESIVE Adhesives Neoprene WB is a nonstaining polychloroprene that contains a high percentage of gel polymer for superior processability. Neoprene WB contains a high percentage of gel polymer, which gives it good processing characteristics. Compounds based on Neoprene WB are firm and have very low nerve. They are fast-extruding, yielding smooth extrudates with good collapse resistance, sharp die definition, and low die swell. They also calender well, yielding smooth sheets with low shrinkage. Vulcanizates of Neoprene WB have the good resistance to heat aging and compression set that is typical of the Neoprene W family. However, because of its gel content, vulcanizates of Neoprene WB are low in tensile strength, elongation, tear strength, and resistance to flex cut growth. For this reason, Neoprene WB is most often used in blends with other types of Neoprene to improve processing at minimum sacrifice in vulcanizate strength. Nonstaining polychloroprene that contains a high percentage of gel polymer for good processability. Offers firm compounds with very low nerve. Provides good resistance to heat aging and compression set. Gives vulcanizates with low tensile strength, low elongation, low tear strength, and low resistance to flex cut growth. Used in blends with other types of polychloroprene.
