The main products currently include rubber sealing rings, rubber gaskets, flange gaskets, rubber shock absorbers, rubber O-rings, V-rings, X-rings, Y-rings, and other rubber products of various forms, sizes, colors, hardness and materials. Seals are used in some precision instruments or pipelines with high sealing requirements.

[0003] During the use of rubber seals, they are limited by the materials and need to consider the use temperature range, medium erosion, etc., which affect their elastic recovery. Therefore, there are many restrictions on their use. For example, when used under high temperature or corrosive sealing conditions, the elasticity of the rubber seals will decrease significantly, which will affect the resilience of the seals and reduce the service life of the rubber seals. For this reason, the utility model provides a rubber seal with high oxidation resistance and sealing properties to solve the above problems. Utility Model Content
