Hydrogenated nitrile rubber (HNBR) is a nitrile rubber to improve the heat resistance, weather resistance for the purpose, by a hydrogenated NBR rubber contained in the polymer backbone from the double bond. Compared with HNBR NBR, except heat resistance and weather resistance can be improved, but also the chemical stability obtained greatly improved, but also both the conventional oil-resistant rubber that does not have high mechanical strength. HNBR in 1984 first in the world to achieve industrialization by the Zeon company, then German Bayer also achieved commercial production. Commercially available HNBR has reached 15 years, during which its excellent heat resistance, oil resistance, high mechanical strength and other characteristics are useful for a variety of purposes. More recently, other industries outside the automotive applications is also a wide range of applications, such as: nitrile rubber roller is used in modern industrial products.
