DuPont Elastomers Neoprene WRT Polychloroprene Rubber

Subcategory: Elastomer, TS; Thermoset

Close Analogs: This former DuPont Dow Elastomers product line is now produced by DuPont Performance Elastomers.

Material Notes:
Neoprene Type WRT is a polychloroprene/2,3 dichloro 1,3-butadiene copolymer, has excellent polymer stability, and a very slow crystallization rate. Physical form: Chips. Color: White to Silver Gray. Distinguishing Features: Slower curing than type W.

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