Waterproof and breathable valve series
The rapid development of new energy vehicles has brought new application opportunities for waterproof breathable valves. In the battery management system, waterproof breathable valves not only need to achieve basic waterproof and breathable functions, but also possess special properties such as explosion-proof and flame-retardant features. This requires manufacturers to continuously improve material formulations and structural designs to meet the specific needs of new energy vehicles. For example, new composite materials with high temperature resistance and corrosion resistance are adopted, and integrated breathable valves with multiple protective functions are developed.
The technical requirements of the automotive industry for waterproof breathable valves are mainly reflected in the following aspects: First is durability. The product is required to withstand harsh environments such as long-term vibration and temperature changes. Second is reliability. It must ensure stable performance throughout the service life. Third is environmental friendliness. It needs to comply with the environmental protection standards of the automotive industry. These requirements drive the continuous innovation of waterproof breathable valve technology, leading to the development of new products that are thinner, stronger, and more intelligent.
