CR Foam
CR Rubber or CR Foam is a polymer known as “neoprene” or “chloroprene”.
It is also a diene-based elastomer. CR Foam has good chemical stability & usefulness over a wide temperature range. It also has a good balance of properties. Among the synthetic elastomers, CR Foam has a unique structure with an optimum property balance.
