One of the main functions of automotive seals is to ensure the sealing performance of the vehicle. Whether it's the car doors, windows, or hood, sealing strips can effectively prevent moisture, dust, and air from entering. This sealing effect not only protects the electronic devices and interior of the car, but also enhances passenger comfort and reduces noise interference.

The sealing strip can also play a role in preventing corrosion. In adverse weather conditions such as rain and snow, sealing strips can prevent moisture from coming into contact with the metal parts of the vehicle body, thereby reducing the possibility of corrosion. In addition, the sealing strip can also protect the vehicle body from external objects such as small stones, reducing the damage caused by them.
