Tag: HNBR o-ring

HNBR rubber material, also known as hydrogenated nitrile butadiene rubber, is an engineered elastomer developed from nitrile rubber (NBR) through selective hydrogenation. The modification of the polymer backbone gives HNBR a different balance of heat resistance, ozone resistance, mechanical strength, abrasion resistance, and chemical stability compared with conventional NBR. For sealing applications, however, HNBR should not be selected simply because
