HNBR Compounds

 
Check up to five results to perform an action.

Hydrogenated Nitrile Butadiene Rubber, also known as Highly Saturated Nitrile (HSN), is produced by hydrogenating acrylonitrile butadiene rubber (NBR).This process improves the heat and ozone resistance, increases tensile strength, and provides superior abrasion resistance. The result is a rubber polymer that performs superior to standard NBR in most sealing applications.

Taking advantage of its inherent properties, HNBR can be compounded to provide excellent service life in applications such as oilfield, automotive, and refrigerants. Dynamic applications requiring long service life or in abrasive environments are especially well suited to HNBR. FDA grades are available. Internally lubricated compounds are superior for extended wear dry air applications.

The service temperature range is generally -40º to 300º F (-40º to 150º C), but can be extended in special applications. PAI offers HNBR compounds in a hardness range from 50 to 90 durometer. Black is the standard color, but other colors are available.
