Product Description

    HNBR is a kind of high-saturated elastic nitrile rubber. HNBR has the same oil-proof performance with NBR(nitrile rubber), but with a higher heatproof performance that can work at **0℃ for a long time due to its highly saturated structure. It also performs as corrosion-resisting, ozone-resisting and compress-resisting. Meanwhile, as a kind of stretched crystalloid rubber,HNBR has a higher stregth than can resist damage and abrasion better. Among all types of rubber, its high-temperature-resisting and high-presure-resisting performances(under **0℃) are at the leading edge.

    Our stuffs studied HNBR for several years and consulted advanced techniques abroad. We used the imported raw rubber and additives to produce these goods with special chemical treatments. Theproducts can be used under the special enviroment as deep wells of oil fields fot its good performances of resisting high-temperature, high pressure and corrosion media. At present the rubber products have been widely used on the downhole tools of horizontal well in ChangQing Oil Field.
