Abbreviation: NBR. Synthetic rubber obtained by copolymerizing acrylonitrile and butadiene, commonly known as nitrile rubber. A type of special rubber with excellent oil resistance. Researched and industrialized in Germany in the 1930s, it was initially marketed under the trade name Buna N, and later Perbunan. During the Pacific War, it was mass-produced in the United States under the name GR-A for military use as part of the government-managed Government Synthetic Rubber Program.
