NBR (Nitrile-butadiene Rubber)

  • NBR is the most widely used elastomer in the seal industry today.
  • Good resistance to low temperature.
  • NBR is often necessary to sacrifice some high temperature resistance.
  • The working temperature range is considered to be -35°C to +120°C (-30°F to +250°F).
  • Good tear, and abrasion resistance.
  • NBR resists oil-based hydraulic fluids, fats, animal and vegetable oils, flame retardant liquids, grease, water, and air.
  • Special low-temperature compounds are available for mineral oil-based fluids.
  • Poor resistance to ozone, sunlight, or weather. They should not be stored near electric motors or other ozone generating equipment.
  • By CR, Hypalon, or PVC blending, the NBR can meet a more specified range of physical or chemical requirements.
