HNBR (Hydrogenated acrylonitrile-butadiene rubber)
HNBR is obtained by selective hydrogenation of the double bond of the butadiene molecules of the NBR rubber. With higher degrees of hydrogenation HNBR exhibits distinctly better resistance to high temperatures, ozone and ageing as well as improved mechanical properties. The media resistance of HNBR is the same as that of NBR.
Application temperature range:
30°C to +150°C
down to -50°C is realistic with special grades
