Nitrile rubber is mainly used to manufacture oil-resistant rubber products. There are five kinds of acrylonitrile content (%) in nitrile rubber: 42 ～ 46, 36 ～ 41, 31 ～ 35, 25 ～ 30, 18 ～ 24. The higher the content of acrylonitrile, the better the oil resistance, but the lower the cold resistance. It can be used in air at 120 ℃ or oil at 150 ℃ for a long time. In addition, it also has good water resistance, air tightness and excellent bonding performance. It is widely used in making various oil-resistant rubber products, various oil-resistant washers, gaskets, sleeves, flexible packaging, flexible rubber tubes, printing and dyeing rubber rolls, cable rubber materials, etc., and has become an indispensable elastic material in the automobile, aviation, oil, copy and other industries.

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.
