EPDM door and window seals have the advantages of anti-aging, high temperature resistance, UV resistance, high tensile strength, corrosion resistance, acid and alkali resistance, ozone resistance, odorlessness, energy saving and environmental protection, etc., in plastic steel doors and windows, aluminum alloy Doors and windows, wooden doors, curtain walls and other architectural fields have been widely used and promoted, which is the best choice in the field of modern door and window sealing.

Flame-retardant silicone sealing strip is famous for its good flame retardant and self-extinguishing performance. The sealing strip has high wind pressure resistance and good watertight performance. In addition to air tightness, the watertightness and wind pressure resistance of aluminum alloy doors and windows are higher than that of plastic steel doors and windows. Well, because the steel lining of steel doors and windows is not connected to the complete frame system at the corners of its profile cavity, the plastic welding angle of the four corners and the terabytes is relatively low. Its wind pressure resistance and watertight performance are about two grades lower than aluminum alloy doors and windows.
