Chloroprene Rubber

CR 232-2 chloroprene rubber, also known as neoprene or polychloroprene, is a synthetic rubber with good heat resistance, high temperature stability, and medium crystallization rate, used in various light-colored rubber products like seals, dust covers, and rubber rolls. 

CR 244, also known as polychloroprene rubber or neoprene, is a synthetic rubber with a milky white appearance, known for its excellent resistance to weathering, chemicals, and ozone, and is used in applications like adhesives and automotive parts. 

SKYPRENE® B-30 by Tosoh is a general purpose, mercaptan-modified chloroprene rubber (CR). Exhibits good crystallization rate, resistance to heat, oil, crystallization and weather. Offers moderate mooney viscosity and good storage stability.

Neoprene is a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene in general has good chemical stability, and maintains flexibility over a wide temperature range.

Higher viscosity form of Y30S with superior heat resistance. Although specifically known and used for its oil resistance, CR is also a very good general-purpose rubber that can replace NR in most of its uses.
