Nitrile Rubber (NBR or Buna-N)

Nitrile is a synthetic rubber composed of acrylonitrile (ACN) and butadiene. The performance and applications for NBR vary according to how ACN and butadiene are combined. With a low ACN content, the rubber has a lower glass transition temperature. A higher ACN content creates resistance to certain types of solvents. Nitriles are popular for their excellent working properties and cost. The wide use of nitrile elastomers, aside from their low cost, is due to their low compression set, high abrasion resistance, and superior tensile strength. NBR O rings have an operating temperature of – 40°C up to 120°C.
