Dynacast Industrial Products Chloroprene Rubber-CR

Dynacast Industrial Products Chloroprene Rubber-CR has several types of polychloroprene. Chloroprene rubber mechanical properties are generally inferior to natural rubber but with superior chemical properties. Over time crystallization results in hardening at temperatures about -10 degree C. CR has very good resistance to ozone. It also has good flame retardance and good tackiness.

Applications & Uses

Chloroprene Rubber is widely used in general engineering applications. It is less resistant than natural rubber to low temperature stiffening but can be compounded to give improved low temperature resistance. It is suitable for use with mineral oils and greases and dilute acids and alkalis, but is not suitable when in contact with fuels. Chloroprene Rubber generally has poorer set and creep than natural rubber.

General uses: Industrial products.
