Problems solved by technology

[0002] In recent years, with the development of rubber gaskets used in the field of instruments and meters towards high performance, low energy consumption and long life, gaskets made of general-purpose rubber such as natural rubber, styrene-butadiene rubber, fluorine rubber, and nitrile rubber have been unable to meet the requirements. The anti-aging and corrosion resistance requirements of the new rubber seals, the rubber seals used on the instrument will be eroded by heat, cold, water, acid, etc. at room temperature, resulting in hardening and discoloration, which not only affects the service life of the instrument, In severe cases, it may even crack and cause leakage, which poses a great safety hazard
