Rubber seals are a kind of general basic element in sealing devices, which play a very important role in the contradiction between leakage and sealing. Solve leaks and seals in man’s conquest of nature. It has been an important way to promote technological progress, prevent and reduce environmental pollution. Rubber seals are a type of rubber products widely used in sealing technology. Because rubber is a valuable elastic polymer material, it has a wide temperature range, and a small stress in different media will produce a large deformation. This deformation can provide contact pressure, compensate for the leakage gap, and achieve the purpose of sealing .
