Hydrogenated nitrile rubber compound
Hydrogenated nitrile rubber has good oil resistance (good resistance to fuel oil, lubricating oil, and aromatic solvents), good ozone resistance, heat resistance, excellent chemical corrosion resistance (good resistance to Freon, acid, and alkali), and high resistance to compression permanent deformation. At the same time, hydrogenated nitrile rubber also has high strength, high tearing performance, and excellent wear resistance. It is one of the rubbers with excellent comprehensive performance.
