Although nitrile rubber has excellent physical and mechanical properties and processing properties, it is not as good as fluororubber and acrylate rubber in acid gasoline and high temperature (150 ℃) environment for a long time. Therefore, hydrogenated nitrile rubber (HNBR) with excellent performance has been developed. In addition, nitrile rubber and carboxyl nitrile rubber (XNBR) with extremely cold resistance and high purity have also been developed.

Because of its excellent oil resistance and physical and mechanical properties, NBR is widely used in the manufacture of various oil-resistant rubber products, such as O-ring, gasket, hose and fuel tank rubber lining, printing drum, oil tank lining, insulating floor plate, oil-resistant shoe sole, hard rubber parts, fabric coating, pipe thread protection layer, pump impeller, wire sheath, adhesive, film for food packaging, rubber gloves and other fields.
