Nitrile rubber

itrile rubber (NBR) is the copolymer of butadiene and acrylonitrile. Its characterized by the good resistance to gasoline and aliphatic hydrocarbon oils, just after the polysulfide rubber, acrylic esters and fluorine-containing rubber, but superior to other general-purpose rubber. Good heat resistance and air tightness, abrasion and water resistance are good, strong cohesive force. The disadvantage are the poor cold resistance and poor ozone resistance , low tensile strength and low elasticity
