Rubber sealing components are a class of general-purpose basic components in sealing devices, used in various fields such as automotive, machinery, electronics, petrochemicals, aerospace, semiconductor manufacturing, and medical. They are one of the key components for the safe operation of industrial equipment. The industry is developing in both traditional and emerging fields.
In the automotive industry, rubber seals are important parts, used in engines, transmissions, doors, and air conditioning systems. In the field of new energy vehicles, the application scenarios have expanded, and the performance requirements for seals are more stringent, with applications in the three-electric systems such as battery pack sealing and electric drive system sealing. The high-pressure hydrogen storage system of hydrogen fuel cell vehicles requires specialized seals capable of withstanding high pressure. The development of intelligent driving has also brought new sealing demands, such as requirements for the waterproof rating of headlight joint seals and sealing solutions for onboard sensors.
In the aerospace field, the performance requirements for seals are high, and carbon fiber composite sealing rings have achieved mass production and application. High-performance materials such as hydrogenated nitrile butadiene rubber (HNBR) are used in this field and are gradually achieving import substitution.
