Sealing technologies refer to methods and materials used to create airtight or watertight seals in various applications. These technologies are essential in industries such as automotive, aerospace, and construction, where preventing leaks and ensuring durability are critical. Common sealing materials include gaskets, O-rings, and sealants, each designed for specific conditions and requirements. Different sealing techniques can be employed, including mechanical seals, adhesive bonding, and thermal sealing. The choice of sealing technology depends on factors like temperature, pressure, and the type of fluids involved. Proper sealing ensures the longevity and efficiency of products, reducing maintenance costs and enhancing safety.
