Nitrile rubber or acrylonitrile butadiene rubber is a co-polymer 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 aging properties and good adhesion to metal. Its recommended operating temperature range is -30°C to + 120°C. It also displays a good resistance to inorganic chemical products except 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.
Nitrile rubber sheeting (NBR) is a synthetic material that is used in a wide range of applications due to its resistance to most petroleum based fluids, oils and greases. Nitrile offers moderate mechanical properties and has satisfactory resistance to aromatic hydrocarbons, but is not suitable for use with ketones.
