Nitrile rubber or acrylonitrile butadiene rubber is a copolymer of butadiene and acrylonitrile. It has good general resistance to oil along with good mechanical properties, especially tensile strength, flexing, compression set and impermeability to gases. It has moderate ageing properties and good adhesion to metal. Its recommended operating temperature range is -30° C to + 120° C. It also displays good resistance to inorganic chemical products except for antioxidant agents and chlorine. It gives satisfactory resistance to general hydrocarbons. Due to its polar nature, we do not recommend its use with polar liquids like ketones, ethers and amines.
