Highly Saturated Nitrile (HSN, HNBR)

Providing Tensile Strength for High-Temperature Sealing Applications

Highly saturated nitrile (HSN), made of synthetic polymers, is also known as hydrogenated nitrile butadiene rubber (HNBR). HSN/HNBR is ideally suited for sealing applications with high temperature conditions that require high tensile strength. The material offers strong and improved chemical resistance over traditional nitrile materials, as well as resistance to ozone and sunlight. Compared to traditional nitrile, hydrogenated nitrile offers superior performance. North Coast Seal can provide more about HSN/HNBR and whether it is the right choice for your sealing application.

The Benefits of HSN/HNBR Materials for O-Rings

Superior Temperature, Fuel, and Abrasion Resistance

If you need a durable, highly resistant material for a tough application, there are many benefits to highly saturated nitrile rubber. This material offers temperature and fuel resistance, abrasion, wear, and compression set resistance, and superior chemical resistance. HSN/HNBR has a high temperature threshold of 150°C (300°F) and a low temperature threshold of -40°C (-40°F). The materials offer excellent resistance to the following:

  • Petroleum-based oil (motor oils)
  • Fuels
  • Lubricating oils
  • Grease
  • Water
  • Steam up to 150°C (300°F)

It is not ideal for applications that require strong acids, chlorinated hydrocarbons, esters, ethers, or ketones. Is highly saturated nitrile the right choice for your sealing application? Let’s discuss the best material for your unique requirements.
