Through the copolymerisation of acrylonitrile and butadiene acrylonitrile butadiene rubber (nitrile rubber) is obtained, an extraordinary good mineral oil and fuel resistance as well as a low pressure permanent set. NBR is thus the ideal oil and fuel resistant sealing material. NBR rubber is, however, not very ozone resistant.
NBR is for Shore-hardness Shore A 30-95 available.
Areas of application: oil and fuel resistant seals, membranes, hoses.
