Hydrogenated NBR elastomer (HNBR) | RADO Gummi GH
2020/06/29· Hydrogenated NBR elastomer is formed by the selective hydrogenation of acrylonitrile-butadiene rubber (NBR). In this process the double bonds are removed from the NBR, making the polymer more resistant to oxygen and increasing its heat resistance significantly. In contrast to NBR, hydrogenated NBR elastomer also offers improved wear resistance
