Hydrogenated Acrylonitrile Butadiene Rubber (HNBR, HSN)
HNBR rubber is a thermoset elastomer or rubber material. It has a fairly high tensile strength and a moderately low ductility among rubber materials. The graph bars on the material properties cards below compare HNBR 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.
