Chloroprene Rubber (CR)
Chloroprene was one of the first successful synthetic elastomers in 1931 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 resistant to sun, ozone, weather and perform well in contact with oils and many chemicals. It also display outstanding physiacal toughness and good resistant to fire.
SERVICE TEMPERATURE
The service temperature of Chloroprene can be designed from -40℃ to 100℃ or up to 125℃ depending on different grades. Generally higher than 100℃, life time will be shortened.
HARDNESS
30 to 90 Shore A are available.
COLOR
Black, white, rust, yellow and blue are available, or any assigned color from customers.
APPLICATION
Chloroprene has been used thousands of diverse environments, including automotive, wire and cable industries.
