Through the selective hydrogenation of nitrile rubber (NBR) its temperature resistance is clearly increased. While NBR can be used with permanent temperatures of up to 100°C, peroxidic cross-linked HNBR rubbers are resistant up to 150°C. HNBR in addition has good mechanical characteristics and a good ageing resistance compared to ozone.
HNBR is for Shore-hardness Shore A 45-98 available.
Areas of application: Drive belts as well as seals and hoses in lubrication, hydraulics, and the cooling area of vehicles.
