HNBR

Hydrogenated Nitrile Butadiene Rubber (HNBR) is produced by selective hydrogenation of NBR, resulting in significantly improved heat resistance (up to 165°C), ozone resistance, and mechanical strength compared to standard NBR. It maintains oil and fuel resistance while offering superior durability in harsh environments. Essential for timing belts, power steering seals, and downhole oil field equipment.
