          HNBR hydrogenated butadiene


          Hydrogenated nitrile rubber, abbreviation: HNBR, or H-NBR. It is a new variety of nitrile rubber (NBR). Hydrogenated nitrile rubber (HNBR) is a highly saturated elastomer obtained by special hydrogenation of nitrile rubber. Hydrogenated nitrile rubber has good oil resistance (good resistance to fuel oil, lubricating oil, aromatic solvents); and because of its highly saturated structure, it has good heat resistance and excellent chemical resistance (to Freon, acid, and alkali have good resistance), excellent ozone resistance, high resistance to compression and permanent deformation; at the same time, hydrogenated nitrile rubber also has high strength, high tear properties, excellent wear resistance and other characteristics, It is one of the rubbers with excellent overall performance.
