[0002] Foam gaskets are an efficient and versatile sealing material widely used in industrial equipment and household products. Foam gaskets can be made of a variety of materials, such as polyurethane, polyethylene, rubber, etc. Each material has its own unique properties, such as temperature resistance, pressure resistance, corrosion resistance, etc. It has good thermal insulation, sealing and lightness, can effectively prevent the leakage of liquids, gases and dust, and improve the sealing and safety of equipment. In some environments that require high temperature resistance or corrosion resistance, in order to enhance the high temperature resistance or corrosion resistance of foam gaskets, so as to meet the use requirements of high temperature resistance or corrosion resistance, lamination treatment is required. In the traditional production process of foam gaskets, the two steps of foaming and laminating are usually carried out separately.
