Descriptions
Hydrogenated Nitrile Butadiene 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, me-thane, 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.
