Nitrile rubber is made from butadiene and acrylonitrile through emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance, strong adhesion force, and good wear resistance. The disadvantage is that low temperature resistant, poor ozone resistance, poor insulation performance, slightly low elasticity. NBR is mainly used to make oil resistant rubber products. It can be used for a long time in air at 120°C or in oil at 150°C.
