Acrylonitrile butadiene rubber (NBR), usually shortened to nitrile or NBR, was developed in 1941 as the first oil resistant rubber. NBR rubber grades with high acrylonitrile content have better oil resistance, whereas low acrylonitrile content gives better low-temperature flexibility and resilience.
