Hydrogenated Nitrile
HNBR compounds are made when hydrogenation of the nitrile base elastomer is obtained. The resulting hydrogenated nitrile has physical characteristics that are much better suited for resistance to heat, oil, pressure, and many industrial chemicals. While HNBR is much more expensive than standard NBR, often it is the only rubber material that can perform in a given environment.
High heat tolerance and excellent physical properties make HNBR the optimal and sometimes only compound choice in many industrial operations including paper making, embossing, steel manufacturing, and laminating.
