Sealing strips play a role in sealing and waterproofing in plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing strips have high requirements on materials. Firstly, they must have strong tensile strength and elasticity, as well as good temperature resistance and aging resistance. At the same time, in order to ensure the close contact between the sealing strip and the profile, the sectional structure of the sealing strip must match the profile of the door and window, and is generally suitable for hanging windows and folding doors and windows.
