Rubber sealing components are circular leak-proof elements made of rubber materials, mainly divided into natural rubber and synthetic rubber. They are a type of general-purpose basic component in sealing devices, used in various fields such as automotive, machinery, electronics, petrochemical, aerospace, semiconductor manufacturing, and medical. China has become the world's largest consumer market for rubber sealing components, with a market size exceeding 100 billion yuan. The industry is showing development trends of high-end, intelligent, and globalization.
They possess high elasticity, mechanical strength, and flexural strength at room temperature, low hysteresis loss, and good electrical insulation properties. Through blending modification, oil resistance and chemical resistance can be improved. Physical forms include solid rubber, latex, liquid rubber, and powdered rubber. High-performance materials such as hydrogenated nitrile butadiene rubber (HNBR) have applications in this field. Related companies have obtained numerous patents in materials, structures, and automated production. In petrochemical and pipeline engineering, rubber sealing components are widely used for sealing pipeline interfaces, and relevant national standards regulate their manufacturing quality and materials.
