Denka Neoprene WB Polychloroprene Rubber
Categories: Polymer; Thermoset; Rubber or Thermoset Elastomer (TSE)

Material Notes: Neoprene Type WB is a polychloroprene homopolymer, has excellent polymer stability, and a medium crystallization rate. Physical form: Chips. Color: White to Silver Gray. Distinguishing Features: Contains high percentage of gel for processing; vulcanizate properties reduced; generally used in blends.

Neoprene W-type Characteristics: Raw polymers: Excellent storage stability; non-peptizable; accelerator required/cure flexibility. Vulcanizates: Good compression set resistance, good heat-aging.

General Neoprene Information: The basic chemical structure of DuPont Dow Elastomers Neoprene is polychloroprene. The polymer structure can be modified by copolymerization with sulfur or 2,3 dichloro 1,3-butadiene to yield a broad range of chemical and physical properties. All types of Neoprene resist degradation from sun, ozone, and weather; perform well in contact with oils and many chemicals; remain useful over a wide temperature range; display outstanding physical toughness, and resist burning inherently better than exclusively hydrocarbon rubbers.

Information provided by DuPont Dow Elastomers.

Denka Performance Elastomer LLC has acquired the Neoprene product line from DuPont Performance Polymers
