Hydrogenated nitrile butadiene rubber (HNBR) is a high-performance elastomer known for its exceptional heat, oil, and chemical resistance. Our EPDM products provide superior properties and resistances that are well suited for outdoor and high temperature applications.

Zetpol® hydrogenated nitrile (HNBR) is ZEON’s toughest, most durable elastomer. Zetpol resists prolonged exposure to 160°C and provides superior resistance to hot fluids. The toughness of Zetpol makes it the ideal choice for automotive belt, seals, and oil field components.

Hydrogenated nitrile provides excellent resistance against motor oil, gas, oxidised fuels as well as lubricating oil deterioration. It is also highly resistant to animal and vegetable fats, fuel, Ozone, solvents and dilute acids.

HNBR O-Rings, sometimes referred to as highly saturated nitrile (HSN), offers a temperature range of -25F to +350F. Used in all oil resistant applications, including exposure to such oil additives as detergents, anti-oxidants and anti-wear agents.

HNBR has excellent mechanical properties and abrasion resistance for actuator seals, rings, gear box and air conditioning applications.

HNBR is widely known for its physical strength and retention of properties after long-term exposure to heat, oil, and chemicals. HNBR has better heat resistance; oxidation resistance; tensile strength and abrasion resistance than standard nitrile (NBR).

HNBR is highly resistant to atmospheric Weathering and ozone. HNBR is used in deep oil well applications which require resistance to heat, crude oil, industrial lubricants, sour gases, (H2S) hot water and steam.

Our hydrogenated nitrile HNBR is a premium grade material that offers superior resistance and physical properties compared to our other nitrile material grades. Also known as saturated nitrile, this material is produced by introducing hydrogen into the saturate of the nitrile material.
