Description

technical field [0001] The invention belongs to the technical field of pump valve materials, and in particular relates to a high-performance and long-life EPDM pump valve body material. Background technique [0002] Seals are components that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from intruding into the interior of machinery and equipment. Seals can be divided into static seals and dynamic seals. Static seals mean that the seals and the device chamber they seal are relatively fixed, while dynamic seals are relatively moving. For example, the seals of valve pumps are usually equipped with constant Reciprocating dynamic seals. [0003] The traditional EPDM (ethylene propylene diene monomer) rubber formula is mainly filled with carbon black, and the EPDM material itself is not wear-resistant, so the EPDM material is used to make dynamic seals (such as O-Ring), in dynamic seals In the...
