HNBR (Hydrogenated Nitrile Butadiene Rubber) is a modified version of nitrile rubber (NBR) known for its enhanced durability and resistance to extreme conditions. The hydrogenation process improves its resistance to heat, oxidation, and ozone, making it suitable for demanding applications. HNBR performs well in temperatures ranging from -40°C to 150°C and offers excellent resistance to oils, fuels, and chemicals.

Advantages

•    Operating temperature range in air: -30 °C to +150 °C.
•    Hardening between 50 Shore A and 95 Shore A.
•    Resistance to mineral oils, fuels and oxidizing media.
•    Very good ozone, aging and weather resistance (especially the fully hydrogenated types).
•    High tear resistance.
•    Very good abrasion properties.

Areas of application

Among other things, in a variety of dynamic and static products that experience dynamic and abrasive loads under the influence of heat and media. As well as hoses and belts, industrial seals for oilfield exploration and processing, and rollers for steel and paper mills.
