Hidrogenated Nitrile (HNBR)

HNBR is created by partially or fully hydrogenating NBR. The hydrogenating process saturates the polymeric chain with accompanying improvements to the ozone, heat and aging resistance of the elastomer and improves overall mechanical properties.
HNBR, like Nitrile, increasing the acrylonitrile content increase resistance to heat and petroleum based oils and fuels, but decreases the low temperature performance.

Primary Uses

O-rings, rubber seals and custom molded rubber components for:
» Oil resistant applications
» Oil well applications
» Fuel systems, automotive, marine, and aircraft
» General Industrial Use

Temperature Range (dry heat)

Low: - 22 °F / - 30 °C

High: 300 °F / 149 °C

Application Advantages

» excellent heat and oil resistance
» improved fuel and ozone resistance (approximately 5X) over Nitrile
» abrasion resistance

Application Disadvantages

» increased cold flow with hydrogenation
» decreased elasticity at low temperatures with hydrogenation over standard nitrile


» acrylonitrile content (ACN) from 18% to 50%
» peroxide vs. sulfur donor cure system
