Also called "Buna-N." Nitrile is a low grade rubber common in older vehicles' fuel systems and is not as ideal for use with biodiesel as the higher grade synthetics. For this reason, it is recommended that nitrile and natural rubber fuel system components be replaced with more suitable fluoropolymers.
A synthetic rubber material that offers chemical and abrasion resistance-a very good general-duty glove. Nitrile also provides protection from oils, greases, petroleum products and some acids and caustics.
(chemical identification: butadiene acrylonirile, Buna N, - NBR): is a copolymer of Butadiene and Acrylonitrile. Most nitrile compounds have a relatively high acrylo content, making them exceptionally resistant to petroleum-base oils and hydrocarbon fuels over a temperature range of -40F to +250F.
Any one of a series of compounds bearing the cyanide radical (-CN); particularly, one of those cyanides of alcohol radicals which, by boiling with acids or alkalies, produce a carboxyl acid, with the elimination of the nitrogen as ammonia.
A nitrile is any organic compound which has a -Câ‰¡N functional group. The -Câ‰¡N functional group is called a nitrile group. In the -CN group, the carbon atom and the nitrogen atom are triple bonded together.
