HNBR is created by partially or fully hydrogenating NBR this improves the ozone, heat and aging resistance of the elastomer and improves overall mechanical properties. HNBR, like Nitrile, increasing the acrylonitrile content increase resistance to heat and petroleum based oils and fuels, but decreases the low temperature performance.
