Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance, and strong adhesion. The disadvantages are poor low temperature resistance, poor ozone resistance, poor electrical properties, and slightly lower elasticity.Nitrile rubber is a synthetic rubber made by copolymerizing butadiene and acrylonitrile. It is a synthetic rubber with good oil resistance (especially alkane oil) and good aging resistance. The acrylonitrile content (%) in nitrile rubber has five types: 42-46, 36-41, 31-35, 25-30, 18-24. The more acrylonitrile content, the better the oil resistance, but the cold resistance decreases accordingly. It can be used in the air at 120 or in oil at 150 for a long time. In addition, it also has good water resistance, air tightness and excellent bonding properties. Widely used in the manufacture of various oil-resistant rubber products, a variety of oil-resistant gaskets, gaskets, casings, flexible packaging, flexible hoses, printing and dyeing rubber rollers, cable rubber materials, etc., becoming indispensable in industries such as automobiles, aviation, petroleum, and copying Elastic material.Item specifics:Shape: O ringsMaterial: RubberColor: BlackMaterial: NBRTemperature resistane: -40 to 100
