Nitrile rubber

Jump to navigation Jump to search


A family of synthetic rubbers made by polymerizing acrylonitrile with butadiene. Nitrile rubbers (NBR), first made in the 1940s, are noted for their resistance to oils and solvents. They are used for gloves, gaskets, hoses, shoe soles, kitchen mats, printing rolls, and food-wrapping films. Some NBR is blended with polyvinyl chloride to increase flexibility. With age, nitrile rubbers can oxidize and become brittle.
