DuPont Elastomers Neoprene FB Polychloroprene Rubber

Subcategory: Elastomer, TS; Thermoset

Close Analogs: This former DuPont Dow Elastomers product line is now produced by DuPont Performance Elastomers. This grade is not a part of the standard product line.

Material Notes:
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.
