CR is a all-round synthetic rubber basing on polychloroprene.
Chloroprene rubber is vulcanized in different systems influencing parameters such as compressibility, oil resistance, weather resistance, and tendency to crystallization.
Use in contact with mineral oils possible, although swelling is stronger compared to NBR, depending on the respective compound specification.
