HNBR O-Ring

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.
