Nitrile Rubber is a copolymer of butadiene and acrylonitrile used as a general purpose, oil resistant polymer in varying applications The resistance of Nitrile Rubber to oil becomes more prevalent with the increase of nitrile in its make-up. This makes it the ideal copolymer for rubber seals and gaskets in the transport sector.
NBR / SBR / Nitrile Rubber
This material is also known as Nitrile-Butadiene, Acrylonitrile Butadiene, or Buna-N. NBR is a copolymer made by reaction of butadiene and acrylonitrile.
Typically, NBR has a service temperature range between -40F and 275 F
In addition to oil, it displays excellent resistance to fuel, solvents, mineral and vegetable oils, and hydraulic fluid. This characteristic may be coupled with a moderate ability to resist exposure to ozone.
