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

  • Similar physical properties to Nitrile, but with:
    • Better heat resistance
    • Better oxidation resistance
    • Higher tensile strength
    • Better abrasion resistance
