Hydrogenated Nitrile Butadiene Rubber

Hydrogenated Acrylonitrile Butadiene Rubber is a highly saturated special elastomer produced by catalytic hydrogenation of NBR. It retains the outstanding oil resistance of NBR while greatly improving heat resistance, ozone resistance and anti-aging performance.

Product Features & Benefits

Temperature Resistance:Continuous service temperature: -55℃ ~ 170℃, short-term peak up to 180℃.

Fluid & Chemical Resistance:Excellent resistance to gasoline,diesel,engine oil, transmission fluid, R134a refrigerant, weak acid/alkali and H₂S sour gas.

Aging & Sealing Performance:Fully saturated backbone provides outstanding ozone, UV and thermal aging resistance; low compression set ensures long-term leak-free sealing.

Mechanical & Dynamic Performance:High tensile strength, tear resistance, abrasion resistance and fatigue resistance.

Typical Applications

Automotive Industry: Engine oil seals, transmission O-rings, fuel line seals, A/C refrigerant seals, new energy battery cooling hoses, vibration dampers.

Oil & Gas Exploitation:HPHT downhole packer elements, BOP seals, mud pump gaskets, submersible pump cable jackets for H₂S sour service.

General Hydraulic Machinery：High-temperature hydraulic seals, high-pressure oil-resistant hoses, rubber rollers, air compressor dust seals, industrial vibration isolators.

High-end Special Fields：Aerospace sealing parts, radiation-resistant nuclear rubber, lithium battery cathode binders.
