It is necessary that car sealing strips can fill various gaps and gaps between body components, and have the functions of shock absorption, waterproof, dust-proof, sound insulation, decoration, etc. to improve the comfort of driving experience and protect the body:

1. Generally, car owners experience strong noise when their cars are running in a certain state, such as high-speed driving, gravel roads and downtown areas. The most likely problem is the sealing performance of the car body. There are many ways to solve the problem. The sealing strip is one of the cost-effective solutions. The car sealing strip is generally configured at the time of delivery, with uneven quality adhesive strips, After a period of use, there will be premature aging, deterioration and disappearance of sealing performance. At this time, a new sealing strip will greatly improve the noise in the car. Automobile sealing strip is a very useful product to solve the noise problem;

2. It can be divided into solid core products (round, square and flat section shapes), hollow products and metal rubber composite products. Among them, metal rubber composite sealing strips account for more than 60%. For rubber sealing strip, section design is very important. First, the shape and size of the sealing lip shall be designed. The sealing lip on both sides shall contact the glass from both sides of the window glass with the same and appropriate force. The length and thickness of the lip edge shall be appropriate. Too thick and too long will increase the lifting resistance of the glass. Too thin and too short will lead to poor guidance and sealing of the glass, resulting in vibration, noise and rain leakage;

3. It can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). Among them, the weather sealing strip is provided with a hollow sponge bubble tube, which has a good function of maintaining temperature and humidity. Common weather sealing strips include door frame sealing strip, trunk sealing strip, engine case cover strip, etc. Common sealing strips include front and rear windshield sealing strips, corner window sealing strips, inner and outer side strips, etc.
