DuPont Performance Polymers Neoprene FB Polychloroprene Rubber  (discontinued **)

Neoprene Type FB is a chloroprene/sulfur copolymer, has good polymer stability, and a medium crystallization rate. Physical form: Cheese-like solid. Color: Brown. Distinguishing Features: Fluid at 50°C; contains thiuram.Neoprene G-type Characteristics: Raw polymers: Limited storage stability; peptizable to varying degrees; no accelerators necessary; and fast curing, but safe processing. Vulcanizates: Best tear strength; best flex; best resilience.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.This former DuPont Dow Elastomers product line is now produced by DuPont Performance Elastomers.
