Nitrile Butadiene Rubber Application Classification

Nitrile butadiene rubber (NBR) is produced by emulsion polymerization of butadiene and acrylonitrile. It is primarily produced using low-temperature emulsion polymerization and exhibits excellent oil resistance, high abrasion resistance, good heat resistance, and strong adhesion. Its disadvantages include poor low-temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. NBR is mainly used to manufacture oil-resistant rubber products. Abbreviated as NBR, it is a synthetic rubber obtained by copolymerizing butadiene and acrylonitrile. It is a synthetic rubber with good oil resistance (especially alkane oils) and aging resistance. The acrylonitrile content (%) in NBR varies in five ranges: 42-46%, 36-41%, 31-35%, 25-30%, and 18-24%. Higher acrylonitrile content results in better oil resistance, but correspondingly lower cold resistance. It can be used for extended periods in air at 120 degree centigrade or in oil at 150degree centigrade. Furthermore, it possesses good water resistance, airtightness, and excellent adhesion properties. Widely used in the manufacture of various oil-resistant rubber products, various oil-resistant gaskets, washers, sleeves, flexible packaging, flexible hoses, printing and dyeing rollers, cable adhesive materials, etc., it has become an indispensable elastic material in the automotive, aviation, petroleum, and photocopying industries. Nitrile rubber application classification: Depending on the acrylonitrile content, products are used in high oil-resistant products and products with balanced low-temperature properties, fuel oil pipes, solvent-resistant and oil-resistant parts, printing rollers, belts, foamed products, shoe soles, PVC modification, and many other applications.
