Nitrile Butadiene Rubber, NBR liquid, Carboxyl NBR Latex

Nitrile butadiene rubber (NBR) is a copolymer made of acrylonitrile and butadiene monomers. It is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance, and adhesion. Strong relay. Its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity.

Nitrile rubber is mainly used to make oil-resistant rubber products.
There are five types of acrylonitrile content (%) in nitrile rubber: 42 to 46, 36 to 41, 31 to 35, 25 to 30, and 18 to 24. The higher the acrylonitrile content, the better the oil resistance, but the cold resistance decreases accordingly. It can be used for a long time in air at 120℃ or in oil at 150℃. In addition, it has good water resistance, air tightness and excellent bonding properties.
It is widely used in the production of various oil-resistant rubber products, various oil-resistant gaskets, gaskets, sleeves, flexible packaging, soft hoses, printing and dyeing rubber rollers, cable rubber materials, etc. It has become indispensable in the automobile, aviation, petroleum, copying and other industries. elastic material.
