Hydrogenated Nitrile (HNBR)
HNBR is produced through the selective hydrogenation of NBR (aka Nitrile, Buna-N), resulting in varying degrees of saturation of the polymeric chain, and varying degrees of enhanced physical strength and chemical resistance properties. The result is a material that does not react as easily to oxygen and is thus significantly more heat resistant than NBR. In addition, HNBR offers better wear behavior in dynamic applications.
Features & Benefits
