Sealing strips, often referred to as gasket or weatherstripping, are materials designed to create a tight seal between two surfaces. They can be made from various materials, including rubber, silicone, foam, and plastic, depending on the specific requirements of the application. The primary function of sealing strips is to prevent the ingress of unwanted elements such as air, water, dust, and noise. This sealing process is vital in maintaining the desired internal environment of products ranging from vehicles to buildings.
