HNBR O-Ring Material Development

The HNBR is the improved hydrogenated alteration of nitrile butadiene rubber. The technique saturates the NBR butadiene section with hydrogen. It minimizes the double bond numbers in NBR and forms outstanding material while maintaining its fundamental properties. This process achieves extreme resistance to ozone, abrasion, greases, etc.

The HNBR can be altered the same way as other O-rings materials, depending on the applications and industry. It happens by adjusting the acrylonitrile content amount.  Lowering the ACN content makes the O-ring ideal for low-temperature applications.

HNBR & NBR Differences

The following shows the differences between HNBR and NBR materials utilized for forming various components, like O-rings.

  • Definition: HBNR means hydrogenated nitrile butadiene rubber, while the NBR is an acrylonitrile and butadiene copolymer.
  • Saturation: NBR has low saturation, while HNBR has very high.
  • Tensile Strength: HNBR has comparatively higher tensile strength than the NBR ones.
  • Applications: NBR is applicable for synthetic rubber products, including O-rings, belts, and hoses. The HNBR is utilized for industrial and automotive applications.
