Sealing is an important indicator of the overall quality of a car, and car sealing strips are one of the important components that determine the quality of this indicator. They are widely used in car body parts such as front and rear windshields, doors, windows, engine compartments, and trunk, filling the gaps between body components. They have functions such as shock absorption, waterproofing, dust prevention, sound insulation, and decoration, and play a maintenance role for drivers, passengers, and the whole car.

There are various ways to classify automotive sealing strip products, usually based on factors such as the title of the device part (component), the type of material, the quantity of composite materials, and the working characteristics. The most commonly used classification method is based on the titles of the device parts (components), including engine compartment sealing strips, front and rear windshield sealing strips, door frame sealing strips, door sealing strips, door glass guide groove sealing strips, lower door dust strips, door sill inner and outer sealing strips, side window sealing strips, sunroof sealing strips, roof cover sealing strips, trunk (luggage compartment) sealing strips, etc.
