Hydrogenated acrylonitrile butadiene rubber (HNBR)

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.
