Acrylonitrile-Butadiene NBR O-Rings

Copolymers of butadiene and acrylonitrile are known by several generic names, Buna N, Nitrile Rubber and NBR.

NBR is the most common polymer for petroleum fluid, gas, water and hydraulic applications. Good abrasion resistance, tensile strength and compression set resistance. The physical properties of acrylonitrile-butadiene (NBR) sealing compounds are dependent upon the acrylonitrile percentage content, which range from 18% to 50%.

A higher acrylonitrile percentage content gives rise to an enhanced resistance to fuels and oils, but with a corresponding reduction in elasticity and an adverse effect on resistance to compression set. NBR seals have good mechanical properties and resistance to wear, but are not resistance to ozone and ultraviolet degradation.
