What type of polymer is NBR?
Acrylonitrile butadiene rubber (NBR), usually shortened to nitrile, is an unique elastomer. It can be produced by free-radical emulsion polymerization of butadiene with 15 to 45 percent acylonitrile either hot (hot rubber) or cold (cold rubber):
Is NBR a polymer?
NBR is the polymerization of Acrylonitrile (CH2=CHCN) and Butadiene (CH2CH-CH=CH2) into one large multiple-unit chains. 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.
Is nitrile a polymer?
Nitrile, also known as Buna-N or NBR (nitrile-butadiene rubber) is a type of synthetic rubber polymer. It’s a copolymer made up of a combination of acrylonitrile and butadiene molecules.
What are the uses of nitrile rubber?
The uses of nitrile rubber include disposable non-latex gloves, automotive transmission belts, hoses, O-rings, gaskets, oil seals, V belts, static & dynamic hydraulic seals, synthetic leather, printer’s form rollers, and as cable jacketing; NBR latex can also be used in the preparation of adhesives and as a pigment …

What is nitrile rubber used for?
nitrile rubber (NBR), also called nitrile-butadiene rubber, an oil-resistant synthetic rubber produced from a copolymer of acrylonitrile and butadiene. Its main applications are in fuel hoses, gaskets, rollers, and other products in which oil resistance is required.
What is the difference between nitrile and neoprene?
The key difference between neoprene and nitrile rubber is that neoprene is produced by emulsion polymerization of chloroprene (2-chloro-1, 3-butadiene), whereas nitrile rubber is produced by emulsion polymerization of copolymers of butadiene and acrylonitrile.
What is nitrile butadiene latex?
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. Trade names include Perbunan, Nipol, Krynac and Europrene. This rubber is unusual in being resistant to oil, fuel, and other chemicals.
What is nitrile butadiene rubber foam?
NBR (Nitrile Butadiene Rubber) is a synthetic co-polymer with various butadiene monomers. NBR Foam also has different commercial names such as Perbunan, Nipol & Europrene. The synthetic rubber (like NBR) is usually resistant to oil & chemicals. If we have more nitrile within the polymer, the behavior changes.
