Standard medium & high ACN grade. This low degree of hydrogenation product has excellent resistance to oil and chemical media, as well as good heat aging resistance and excellent dynamic fatigue performance. It has excellent processing performance and especially suited for synchronous belts , O-rings, gaskets, oil seals and oil industry accessories, etc.
Excellent permanent set at low temperature and oil resistance，especially suitable for oil seals, rolls and dynamic oil field components；Hydrogenated nitrile rubber has good oil resistance (good resistance to fuel oil, lubricating oil, and aromatic solvents); And due to its highly saturated structure, it has good heat resistance, excellent chemical corrosion resistance (good resistance to fluorocarbons, acids, and alkalis), excellent ozone resistance, and high resistance to compression permanent deformation; Hydrogenated nitrile rubber also has the characteristics of high strength, high tear resistance, and excellent wear resistance, making it one of the rubbers with extremely excellent comprehensive performance
Hydrogenated butadiene-acrylonitrile rubber (HNBR) is a highly saturated elastomer which is treated by catalytic hydrogenation of nitrile rubber (NBR). Compared with NBR, the molecular structure of HNBR contains a small amount or no carbon-carbon double bonds. The HNBR has better thermal oxygen aging, ozone resistance, radiation resistance, chemical medium resistance (acid, alkali, methane, refrigerant, hydrogen sulfide) and good dynamic properties than NBR, while maintaining the oil resistance and wear resistance of NBR. The HNBR is a special rubber with excellent comprehensive properties, which is a national strategic material.
Standard medium & high ACN grade with excellent dynamic properties and processing, especially suited for synchronous belts , O-rings, gaskets, oil seals and oil industry accessories, etc.
Hydrogenation of Nitrile Butadiene Rubber (HNBR) refers to the process of chemically modifying nitrile butadiene rubber (NBR) by adding hydrogen atoms to the polymer's carbon-carbon double bonds. HNBR is a copolymer made from acrylonitrile and butadiene, which gives it excellent oil, fuel, and chemical resistance.
