Nitrile rubber , also known as nitrile butadiene rubber , NBR , Buna-N , and acrylonitrile butadiene rubber , is a synthetic rubber derived from acrylonitrile ACN and butadiene. This rubber is unusual in being resistant to oil, fuel, and other chemicals. NBR is used in the automotive and aeronautical industry to make fuel and oil handling hoses , seals, grommets, and self-sealing fuel tanks. It is also used in the nuclear industry to make protective gloves. Nitrile butadiene is also used to produce moulded goods, footwear, adhesives, sealants, sponges, expanded foams, and floor mats. Its resilience makes NBR a useful material for disposable lab, cleaning, and examination gloves. Nitrile rubber is more resistant than natural rubber to oils and acids , and has superior strength, but has inferior flexibility. The first commercial production began in Germany in The raw materials came from the Polish coalfields. Emulsifier soap , acrylonitrile, butadiene , radical generating activators, and a catalyst are added to polymerization vessels in the production of hot NBR. Water serves as the reaction medium within the vessel. Because several monomers capable of propagating the reaction are involved in the production of nitrile rubber the composition of each polymer can vary depending on the concentrations of each monomer added to the polymerization tank and the conditions within the tank.

Acrylonitrile Butadiene Rubber NBR or Nitrile rubber is one of the most popular compounds for automotive applications. It also is well known as Buna-N. This name came from one of the first base polymers patented in , therefore people commonly use this name for all classes for Nitrile to this day. The amount of Acrylonitrile is varied to provide different range of oil resistance the base polymer will have. Typical ranges are between 14 to 50 percent acrylonitrile.

The amount of Acrylonitrile is varied to provide different range of oil resistance the base polymer will have. Typical ranges are between 14 to 50 percent acrylonitrile. As the Acrylonitrile increase the polymer will have greater oil and fuel resistance.

Nitrile rubber is a synthetic rubber copolymer of acrylonitrile ACN and butadiene that you may know better under trade names like Nipol, Krynac and Europrene N. Why might you consider specifying nitrile for your application? This is partly because it displays excellent resistance to petroleum-based oils, fuels, water, alcohols, silicone greases, hydraulic fluids. However, it also has a good balance of desirable working properties like low compression set, high abrasion resistance and high tensile strength. Nitrile is a family of unsaturated copolymers of 2-propenenitrile and butadiene monomers 1,2-butadiene and 1,3-butadiene.
