Filter Cartridge Sealing Strip and End Cap Solution

As a key component, the function of the filter end cap is mainly to seal both ends of the filter material and support it, ensuring the stable operation of the filter element. It is usually stamped from steel plates, has various shapes, and is installed on vehicles and engines. In mechanical motion, the filter end cap is subjected to enormous stress, thus requiring extremely high pressure resistance of the material. Usually, one side of the end cap is stamped with a groove for placing the filter material end face and adhesive, while the other side is bonded with a rubber seal to double seal the filter material and filter element channel.

Material selection is crucial, as steel plates have high strength but heavy weight; Foamed polyurethane is much lighter. Therefore, Changneng has introduced a solution for the sealing strip and end cap of the filter cartridge. Our product has the advantages of rapid demolding and good mold filling, good adhesion with cardboard, high physical properties, and good compression deformation.
