HNBR is made via selective hydrogenation of the NBR butadiene groups which improves the temperature and ozone resistance considerably. HNBR is widely known for its physical strength and retention of properties after long-term exposure to heat, oil, and chemicals.

HNBR custom molded seals, gaskets, orings, and o-rings, for mechanically demanding service. Heat and Chemical resistant.

In sealing technology, the significantly more expensive HNBR, which is a proven standard material for automotive engine timing belts, is primarily used in applications where higher temperatures and/or mechanical strength are required.

Dec 6, 2016 · HNBR elastomers are changing the game for sealing and manufacturing companies. Made from hydrogenating acrylonitrile butadiene rubber (NBR), the compound meets higher temperatures, retains better resistance and has …

Seals for automotive fuel handling systems. Seals for general industrial usage. Standard Compound: -30°F to +300°F. (Dry Heat Only) Special Compounds: -76°F to +347°F. Like Nitrile, increasing acrylonitrile content improves oil resistance …

Independence Seal offers premium HNBR seals, designed to meet the needs of various high-performance applications. Our custom HNBR lip seals integrate a robust metal casing, available in mild carbon steel (CRS) or 304 stainless steel, with an HNBR lip element, providing exceptional durability and resistance.

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

Feb 22, 2021 · HNBR o-rings are high-performance seals that are actively used in multiple industries. HNBR is an upgraded — i.e. hydrogenated, hence the H — variation of nitrile butadiene rubber (NBR).

Obtained by hydrogenating nitrile rubber, HNBR seals offer outstanding physical properties. In particular, abrasion resistance, combined with good mechanical properties at elevated temperatures, plus excellent resistance to many chemically aggressive technical oils.

Highly saturated nitrile (HSN), made of synthetic polymers, is also known as hydrogenated nitrile butadiene rubber (HNBR). HSN/HNBR is ideally suited for sealing applications with high temperature conditions that require high tensile strength.
