O Ring Gasket Material 70 Shore A HNBR Rubber Compound
70 Hardness Shore A black hydrogenated nitrile HNBR compound rubber molded O-ring and gasket material
Description:
HNBR: it is a kind of highly saturated elastomer get by special hydrogenation processing of NBR, it has good oil resistance (with good resistance to fuel oil, lubricating oil and aromatic solvent), in addition, due to its highly saturated structure, it has good heat resistance, good chemical corrosion resistance (good resistance to Freon, acid and alkali), excellent resistance to ozone and higher resistance to compression permanent deformation; at the same time, HNBR also has the characteristics such as high strength, high tear performance and excellent wear resistance, etc, it is one of rubbers with very excellent comprehensive performance.
The temperature resistance is 130℃-180℃ and cold resistance is -55℃--38℃, is widely used in automobile and oil field, etc, industrial areas.
