Problems solved by technology

[0002] Nitrile rubber has excellent oil resistance and good wear resistance, so it is often used as a cable sheath material, but its cold resistance is poor, its mechanical properties are low, and it is easy to crack. As a result, the cable cannot be wrapped and protected, and it is not suitable for some low temperature applications. Seals in the environment, hindering the use of nitrile rubber
