A nitrile is an organic chemical that contains a cyano functional group (subunit), CN-, in which the carbon and nitrogen atoms have a triple bond i.e. Câ¡N-. The general chemical formula of a nitrile is RCN, where R is the organic group.
The chemical name for Nitrile rubber is Butadiene Acrylonitrile. However, most commonly it is referred to as NBR or Buna-N. NBR is probably the most common solenoid valve seal material and it is considered the standard material for neutral fluids by many. NBR is also the standard material for O-rings. NBR can stand media temperatures to approximately 90 degrees Celsius on continuous basis, and higher temperatures intermittently.
