HNBR (Hydrogenated Nitrile Butadiene Rubber)

  • HNBR has excellent resistance to common automotive fluids (e.g., engine oil, coolant, fuel, etc.) and many industrial chemicals.
  • The working temperature range is considered to be -40°C to +165°C.
  • Good resistance to long-term exposure to heat, oil, and chemicals. Also good with aging resistance and low temperature resistance.
  • The automotive market is the largest consumer, using HNBR for a host of dynamic and static seals, hoses, and belts.
  • Disadvantage: expensive.
