Hydrogenated nitrile 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 maintains the oil resistance and wear resistance of NBR. The HNBR is a special rubber with excellent comprehensive properties, which is a national strategic material.

Currently, HNBR is widely used in aerospace, automotive industry, oil drilling, machinery manufacturing, textile & printing and other fields. It is mainly used in automobile fuel system components, auto transmission belts, drilling confinements, packer rubber of oil wells, submersible pump cable sheaths of ultra-deep wells, bops, directional drillings, stator motor matching hoses of offshore oil drilling platforms, seals o faeronautics and astronautics, tank track pads, foam cushioning materials, seals of nuclear industry, hydraulic pipes, air conditioning seal products, textile & printing rubber rollers, etc.
