HNBR performs excellently in high-temperature environments, maintaining strong physical properties within a temperature range of 150°C to 180°C, significantly higher than conventional nitrile rubber. This makes HNBR ideal for applications in high-temperature conditions, such as engine seals and oil and gas equipment.
HNBR exhibits excellent resistance to oils, fuels, solvents, and various chemicals, making it particularly valuable in the petrochemical, automotive, and other harsh environment sectors. It resists degradation from acids, alkalis, and chlorides, adding significant value in industries where exposure to aggressive substances is common.
HNBR is known for its superior wear resistance and aging properties. Due to its hydrogenated molecular structure, it offers better crack resistance and oxidation stability compared to conventional nitrile rubbers. This enhances the longevity of equipment and reduces maintenance needs over time.
HNBR demonstrates excellent physical and mechanical properties, including hardness, tensile strength, and elongation. It also offers outstanding elasticity and tear resistance, making it well-suited for applications where high mechanical stress is involved, such as hydraulic seals and power transmission components.
While HNBR is primarily known for its high-temperature and chemical resistance, it also retains a degree of flexibility at low temperatures, typically in the range of -30°C to -40°C, making it suitable for applications in cold environments.
As a hydrogenated high-performance material, HNBR is free of harmful solvents or additives, aligning with the growing demand for environmentally friendly materials in modern industry. Additionally, its durability helps reduce replacement frequency, supporting sustainability and long-term use.

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.

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.
