Therban
Therban® is a hydrogenated nitrile butadiene rubber (HNBR) in which part or all of the nitrile double bonds have been hydrogenated.
While all HNBR types provide outstanding strength, heat resistance, and oil resistance superior to standard NBR and other polymers, Therban® offers a wide range of grades designed to perform exceptionally well in the most demanding environments.
