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. [1] Trade names include Perbunan, Nipol, Krynac and Europrene. This rubber is unusual in being resistant to oil, fuel, and other chemicals.

In 2002, world production capacity was estimated at 5 million tonnes per year, [5] [8] rising to about 6 million tonnes by 2017. [9] Acetonitrile and hydrogen cyanide are significant byproducts that are recovered for sale. [5] In fact, the 2008–2009 acetonitrile shortage was caused by a decrease in demand for acrylonitrile.

The structure of a nitrile: the functional group is highlighted blue. In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group.The name of the compound is composed of a base, which includes the carbon of the −C≡N, suffixed with "nitrile", so for example CH 3 CH 2 C≡N is called "propionitrile" (or propanenitrile).

Micronized rubber powder (MRP) is classified as fine, dry, powdered elastomeric crumb rubber in which a significant proportion of particles are less than 100 μm and free of foreign particulates (metal, fiber, etc.). MRP particle size distributions typically range from 180 μm to 10 μm.
The Stevenson Plan, also known as the Stevenson Restriction Scheme, was a scheme by the British government over the period 1922 to 1928 to restrict rubber supply in order to increase rubber prices. [ 1 ] [ 2 ] During World War I , there was a substantial increase in rubber supply due to high demand.
Butyl rubber gloves. Butyl rubber, sometimes just called "butyl", is a synthetic rubber, a copolymer of isobutylene with isoprene. The abbreviation IIR stands for isobutylene isoprene rubber. Polyisobutylene, also known as "PIB" or polyisobutene, (C 4 H 8) n, is the homopolymer of isobutylene, or 2-methyl-1-propene, on which butyl rubber is ...
Nitrile is toxic and a carcinogen. Does that mean that nitrile rubber is also toxic and a carcinogen? I am somewhat worried because i use nitrile gloves for my anatomy class and will stop using them if they are hazardous. —Preceding unsigned comment added by 128.195.63.178 (talk • contribs)
