www.parker.comACRYLONITRILE-BUTADIENE (NBR) Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene terpolymer. The acrylonitrile content of nitrile sealing compounds varies considerably (18 to 50%.) Polymers with higher ACN content exhibit less swell in gasoline and aromatic solvents, while lower ACN polymers exhibit better compression set and
General Properties of Elastomers
www.elbex-us.comNitrile, or Buna-N, is a copolymer of butadiene and acrylonitrile. It is a general purpose oil-resistant polymer. Nitrile has a typical service temperature range between –40° F and +275° F. ADVANTAGES: Nitrile has excellent resistance to oil, gasoline, solvents, mineral and vegetable oils, hydraulic fluid, and fuels. It is
