Hydraulic hose material of NBR

Nitrile rubber and acrylonitrile-butadiene is obtained by emulsion polymerization, emulsion polymerization nitrile rubber is mainly produced by low temperature, excellent oil resistance, high abrasion resistance, good heat resistance, adhesive power . The disadvantage is poor low temperature resistance, ozone resistance is poor, poor insulation, elastic lower. Nitrile rubber is mainly used for oil-resistant rubber products. Acronym NBR, prepared a synthetic rubber copolymer of butadiene and acrylonitrile. The oil (in particular paraffin oil), anti-aging better performance synthetic rubber. NBR acrylonitrile content (%) 42 ~ 46,36 ~ 41,31 ~ 35,25 ~ 30, 18 ~ 24 and so on five. Acrylonitrile content, the more oil the better, but the cold is correspondingly reduced. It can be used in an oil or in the long-term 150 ℃ 120 ℃ in air. In addition, it has good water resistance, air tightness and excellent bonding propertie.
