Products name :  Hydrogenated Nitrile Butadiene Rubber (HNBR) 
HNBR is high-saturated elastomer,which is processed by hydrotreating nitrile rubber. it has excellent
oil resistance ( like fuel oil,  Lubricating oil,other series solvent of fragrance ) , high temperature resistance 
owing to its high-saturated properties and Excellent resistance to chemical corrosion especially for those
 Freon,acid , alkali etc . besides above ,it also has Excellent ozone resistance, high resistance to compression and
 permanent deformation; high tensile strength , which make it to be one of the most excellent rubber. 
Main application :  
It's widely used in oil field , automobile industry .
