Nitrile butadiene rubber or nitrile rubber is copolymerized by acrylonitrile and butadiene with acrylonitrile content ranging from 18% to 50%. The higher the acrylonitrile content, the better the resistance to petrochemical hydrocarbon fuel. However, the performance under low temperature will be poorer. The normal temperature range for product use is from -20°C to 140 °C. Nitrile rubber is one of the most commonly used rubbers for oil seals and O-rings.
