Chlorosulfonated Polyethylene Rubber (CSM)

CSM rubber is a thermoset elastomer or rubber material. It has a moderately low tensile strength among the rubber materials in the database. The graph bars on the material properties cards below compare CSM rubber to other rubber materials (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
