Description

Hydrogenated Nitrile Rubber (HNBR)

Material Description

Hydrogenated Nitrile (HNBR), also known as Highly Saturated Nitrile (HSN), is a synthetic polymer that is obtained by saturating the double bonds in nitrile=s butadiene segments with hydrogen. This special hydrogenation process reduces many double bonds in main chains of NBR polymers. This process results in the superior heat, ozone, chemical resistance and mechanical characteristics of HNBR over standard Nitrile.

Acrylonitrile Content

Just like NBR, there are different levels of Acrylonitrile (ACN) content in different HNBR polymers. The ACN content can be varied from 17% to 49%. Lower ACN content gives better low-temperature properties but lesser resistance to fuels and polar lubricants. Higher ACN content gives inferior low-temperature properties but improves fuels and polar lubricants resistance. Standard HNBRs typically have 36% ACN content.

Cure system: Peroxide-cured

HNBRs are usually peroxide-cured but can also be sulfur-cured to improve flexible properties in dynamic systems. However, sulfur-curing will reduce the heat resistance and cause an inferior compression set.

Temperature Range:

Standard Low Temp: -55°C (-67°F)
Standard High Temp: 150°C (302°F)
