The sealing strip is a kind of elastic band-shaped or rod-shaped material, which is made of rubber and is a necessary product for door and window components. . The sealing strip can play the role of cushioning and reduce too much noise and damage caused by vibration. Not only that, the sealant strip can also prevent some rainwater, sand and dust from invading the house, and can completely seal the doors and windows. A good sealant strip and a good installation process can even isolate the air. The sealing strip, as the name implies, is used for sealing, but its function can not only achieve a good sealing effect, but also play the role of sound insulation, heat insulation and shock absorption.
