Buna-N is the American term for Nitrile rubber, it is also known as: Butadiene Acrilonitrile, Perbunan or NBR rubber. Grades vary on their properties due to their acrylonitrile content. A high acrylonitrile content has a better oil resistance while a low acrylonitrile content has better resilience and low temperature flexibility.
Nitrile has outstanding resistance to: oils, petrols, solvents and lubricants but has poor ozone resistance. As such, nitrile gaskets are particularly suited for use with fats, oils, fuels and other liquids contaminated by these.
We stock nitrile in commercial, specification and white food quality grades. It is ideally used in temperatures ranging from -20ºC to +110ºC (Dependant on grade).
Popular examples of gaskets made from nitrile are: Oil gaskets and Cover gaskets.
