HNBR, commonly called Hydrogenated Nitrile or Highly-Saturated-Nitrile is a special Nitrile material formulated to increase strength and reduce fluid attack.  The process eliminates double-carbon chemical bonds that allow chemical attack in conventional NBR materials.  The resulting compounds have much higher strength, abrasion resistance and chemical resistance.  HNBR is not recommended for use with strong acids of chlorinated hydrocarbons.  The wider temperature range, toughness and wear resistance make C-7018 an excellent choice for use in oil field applications and other applications from -29°C to +160°C (-20°F to +320°F).
