Top Uses of Hydrogenated Nitrile Rubber (HNBR) in 2025
Top Uses of Hydrogenated Nitrile Rubber (HNBR) in 2025
Hydrogenated nitrile rubber (HNBR) is a high-performance synthetic rubber made from nitrile rubber (NBR) by hydrogenation modification. It has excellent high temperature resistance (-40°C to above 150°C), oil resistance, chemical corrosion resistance and mechanical strength. In 2025, with the development of new energy, high-end manufacturing and green industry, the application scope of HNBR will be further expanded and become a key material in many industries.
As a global leading HNBR supplier, Dawn is committed to developing high-performance HNBR solutions to meet the stringent needs of automotive, energy, aerospace, and other fields.
Automotive Industry: Improving Durability and Efficiency
Electric Vehicle (EV) Battery Seals
In 2025, the global electric vehicle market continues to grow. HNBR has become the preferred material for battery pack seals due to its excellent resistance to high temperatures and coolants.
Fuel System Components
With the popularity of biofuels (such as ethanol and gasoline), traditional rubber is prone to swelling failure, while HNBR can withstand the corrosive additives in biofuels and is widely used in key components such as fuel pipes and O-rings.
Turbocharger Hose
The turbocharger system of high-performance engines requires high temperature (>150°C) and oil-resistant materials. HNBR hoses maintain excellent elasticity under extreme conditions to reduce the risk of leakage.
Oil and Gas Industry: Reliable Performance in Harsh Environments
Downhole seals and packers
In acidic oil and gas wells containing hydrogen sulfide (H₂S), HNBR's chemical corrosion resistance makes it a core material for downhole tools.
Subsea equipment seals
Deep-sea oil and gas production faces high pressure (>1000bar) and low temperature challenges. HNBR performs well in subsea oil production seals.
Refinery seals and gaskets
Hydrocarbon compounds and acidic media in the refining process will corrode ordinary rubber, while HNBR gaskets can be used stably for more than 5 years.
Industrial Machinery: Reduce Downtime and Maintenance Costs
Hydraulic Seals and O-Rings
Hydraulic systems in mining machinery rely on HNBR seals, which are resistant to high pressure (>5000psi) and wear, reducing the frequency of replacement.
Conveyor Belts and Rollers
In the steel and cement industries, HNBR-reinforced conveyor belts can withstand high wear and impact loads, and their life is 50% longer than ordinary rubber.
Chemical Pump Components
Chemical process pumps transport corrosive fluids (such as sulfuric acid and lye), and HNBR impeller seals can withstand extreme environments with a pH of 1-14.
Emerging Applications in 2025
- Medical Device Seals
- 3D-Printed Flexible Parts
- Automated Robotic Grippers
Applications of Dawn HNBR
The hydrogenated nitrile rubber (HNBR) produced by Dawn Special Elastomer Company has been maturely applied in various products such as automotive timing belts, seals for new energy vehicle motors, refrigerant-resistant O-rings, and aircraft oil pipes, and has been exported to dozens of countries.
