NBR is obtained by emulsion polymerization of butadiene and acrylonitrile, and NBR is mainly produced by low temperature emulsion polymerization.
Excellent oil resistance, high wear resistance, good heat resistance, strong adhesion. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance and slightly low elasticity. NBR is mainly used to make oil resistant rubber products. NBR is a kind of synthetic rubber made from butadiene and acrylonitrile. It is a synthetic rubber with good oil resistance (especially alkane oil) and aging resistance. Acrylonitrile content (%) in NBR is 42 ~ 46, 36 ~ 41, 31 ~ 35, 25 ~ 30 and 18 ~ 24. The higher the content of acrylonitrile, the better the oil resistance, but the lower the cold resistance. In addition, it has good water resistance, air tightness and excellent adhesion. It is widely used in making various oil resistant rubber products, various oil resistant gaskets, gaskets, sleeves, flexible packaging, flexible hose, printing and dyeing cots, cable rubber materials, etc. it has become an indispensable elastic material in automobile, aviation, petroleum, copying and other industries.
