NBR nitrile rubber

Obtained from emulsion polymerization of butadiene and acrylonitrile, acrylonitrile butadiene rubber 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 electrical performance and slightly low elasticity.

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.

NBR has excellent oil resistance, its oil resistance is second only to polysulfide rubber and fluororubber, and has excellent wear resistance and air tightness. The disadvantage of NBR is that it is not resistant to ozone, aromatic, halogenated hydrocarbon, ketone and ester solvents, so it is not suitable to be used as insulating material.
