CR (Neoprene Rubber)

Characteris
ticsChloroprene was one of the first successful synthetic elastomers in 1931 developed by Dupont. It is prepared by emulsion polymerization of chloroprene, or 2-chlorobutadiene. CR is a multi-purpose elastomer which yields a balanced combination of properties. It has good resistance to sun, ozone and weathering and performs well in contact with oils and many chemicals. It also displays outstanding physical toughness and low flammability. Vulcanized CR is flexible and resistant to wear, distortion, direct sunlight, Difluoro dichloromethane, diluted acid, silicon lubricant, and refrigerant such as ammonia. However, it is low resistant to mineral oil, and easily crystallized under low temperature.

Service Temperature
The Service Temperature of Chloroprene can be designed from -40℃ to 150℃ or up to 150℃ depending on different grades. Generally, service life shortened when higher than 100℃.

Hardness
30 to 90 (Shore A).

Color
Black, white, rust, yellow and blue are available, or any assigned color from customers.

Application
Chloroprene is frequently used for R12 refrigerant tolerant seals, as well as rubber parts and seals of home appliances. It is suitable for making parts which has direct contact with the atmosphere, sun, ozone. It also applies to making low flammable, distortion resistant, and chemical resistant rubber product.
