NBR (nitrile rubber) is a copolymer formed by polymerization of acrylonitrile and butadiene. It has excellent oil resistance, high wear resistance, good heat resistance, and strong adhesion. However, NBR rubber has poor low temperature resistance, ozone resistance, poor insulation performance, and slightly lower elasticity.
NBR rubber is mainly used to manufacture oil resistant rubber products, such as various oil resistant gaskets, gaskets, sleeves, flexible packaging, flexible hoses, printing and dyeing rubber rollers, cable adhesive materials, etc. NBR rubber is an essential elastic material in industries such as automotive, aviation, petroleum, and photocopying.
In addition, the performance of NBR rubber may vary depending on the content of acrylonitrile. Generally speaking, the higher the content of acrylonitrile, the better the oil resistance, but the corresponding decrease in cold resistance. The usage temperature range of NBR rubber is usually -25 ℃ to 100 ℃, and it has excellent water resistance, airtightness, and excellent bonding performance.
