Background

Nitrile Butadiene Rubber (NBR) is a copolymer polymerized by acrylonitrile and butadiene monomers, is mainly produced by a low-temperature emulsion polymerization method, and has the advantages of excellent oil resistance, higher wear resistance, better heat resistance and strong bonding force. The disadvantages of the nitrile rubber are poor low temperature resistance, poor ozone resistance, poor insulating property and slightly low elasticity, and the nitrile rubber is mainly used for manufacturing oil-resistant rubber products. The acrylonitrile-butadiene rubber has acrylonitrile content (%) of 42-46, 36-41, 31-35, 25-30, 18-24, etc. The more the acrylonitrile content, the better the oil resistance, but the cold resistance is decreased accordingly. It can be used in 120 deg.C air or 150 deg.C oil for a long period. In addition, it has excellent water resistance, air tightness and excellent adhesion performance.
