Hydrogenated Nitrile Butadiene Rubber

Hydrogenated Nitrile Butadiene Rubber (HNBR) is an important organic polymer material obtained from NBR by catalytic hydrogenation technology.

It has excellent high temperature resistance, low temperature resistance, oxidation stability, ozone stability, and oil resistance.

Product Name:Hydrogenated Nitrile Butadiene Rubber

CAS No.:88254-10-8

HS CODE:4002591000

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.
