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.

NBR is synthesized using an emulsion polymerization technique. In the polymerization vessels, water, emulsifier/soap, monomers (butadiene and acrylonitrile), radical producing activator, and other components are added. The emulsion process produces polymer latex, which is coagulated with various ingredients (e.g., calcium chloride, aluminum sulfate) to generate crumb rubber, which is then dried and compressed into bales. Some specialized items come in crumb form. Most NBR producers produce at least 20 conventional elastomer variations, with one worldwide manufacturer now supplying over 100 grades.
