Good physical properties and chemical resistance to the most common hydraulic fluids makes hnbr an excellent sealing material. hnbr material is often used in vegetable and animal oils as well as high addivated and crude properties mentioned are only valid for test pieces of the corresponding ISO, DIN and ASTM standards.
