丁腈橡胶粉末/Butadiene acrylonitrile rubber

Butadiene acrylonitrile rubber (NBR) is a copolymer of acrylonitrile and butadiene monomer. It is mainly produced by low temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance and slightly low elasticity.

Butadiene acrylonitrile rubber is mainly used to manufacture oil resistant rubber products. Acrylonitrile content (%) in nitrile rubber includes 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 and 18 ~ 24. The higher the content of acrylonitrile, the better the oil resistance, but the cold resistance decreases accordingly. 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 to make various oil resistant rubber products, a variety of oil resistant gaskets, gaskets, sleeves, flexible packaging, flexible hoses, printing and dyeing cots, cable rubber materials, etc. it has become an essential elastic material in automobile, aviation, petroleum, copying and other industries
