Hydrogenated nitrile butadiene rubber is a kind of highly saturated elastomer obtained by special hydrogenation of nitrile butadiene rubber. There are three main preparation methods of HNBR: ethylene acrylonitrile copolymerization, NBR solution hydrogenation and NBR emulsion hydrogenation. Hydrogenated nitrile butadiene rubber has good oil resistance (good resistance to fuel oil, lubricating oil and aromatic solvents); And because of its highly saturated structure, so that it has good heat resistance, excellent chemical corrosion resistance (good resistance to freon, acid, alkali), excellent ozone resistance, high compression resistance permanent deformation performance; At the same time, hydrogenated nitrile butadiene rubber also has high strength, high tearing performance, excellent wear resistance and other characteristics, is one of the comprehensive properties of excellent rubber, widely used in oil fields, automobile industry and other aspects.
