[0002] Rubber seals are generally used for leak prevention. Due to the physical properties of natural rubber, it exhibits high elasticity and slight plasticity at room temperature, possesses excellent mechanical strength, low hysteresis loss, and low heat generation during repeated deformation, resulting in good flexural resistance. Furthermore, as a non-polar rubber, it has good electrical insulation properties. Rubber seals are a common and fundamental component in sealing devices, playing a crucial role in resolving the contradiction between leakage and sealing. Solving leakage and sealing problems has been a vital driving force for technological progress and the prevention and reduction of environmental pollution in humanity's conquest of nature. Rubber seals are a widely used type of rubber product in sealing technology.
