Product Description
Oil Resistant Rubber Strip,Nitrile Rubber Strip  is a copolymer formed by polymerization 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. The relay is strong. The 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. 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 for a long time in the air at 120°C or in oil at 150°C. 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 The elastic material.

Performance of Nitrile Rubber Strip
NBR has excellent oil resistance. Butadiene monomers can be copolymerized into three different chain structures: cis, trans and 1,2-alkylene groups. In a typical NBR structure, the trans form accounts for about 78%. Because NBR contains cyano groups in its molecular chain structure, its oil resistance (such as mineral oil, liquid fuel, animal and vegetable oil and solvent resistance) is better than natural rubber, neoprene rubber and styrene butadiene rubber. Compared with other rubbers, NBR has a wider range of use temperature. Its long-term use temperature is 120oC. At the same time, NBR has good low temperature resistance, and the lowest glass transition temperature can reach -55oC.
