Automobile sealing strip is one of the important parts of automobile. They are widely used in doors, windows, bodies, seats, skylights, recommended chassis and luggage compartment, and have other waterproof and sealing effects. In daily driving, remind everyone not to ignore the maintenance of sealing strip.

The quality of silica gel raw materials will make it difficult to remove the edges of silica gel products. The toughness and tear strength of silica gel raw materials with poor quality are obviously insufficient. It must be difficult to remove the edges in the process of edge removal. 2、 In the forming process, if the product is formed thicker, the burr is actually thicker. The increase of thickness must also lead to the difficulty of edge removal.

The sound insulation of the door is very important, because it is connected with the outside, which is the weak link of sound insulation. The sound insulation of the door mainly depends on the thickness of the door panel and the sealing degree between the window sash and the frame. When we live in high-rise buildings, we will find that the key to why electric heating and air conditioning do not work is that the thermal insulation effect of doors and windows is too poor. The reason for this is that the door and window tightness is too low. Hot air or cold air can enter directly from the gap, and the cold air or hot air in the room overflows seriously. Even if good equipment is installed, the root cause can not be solved. Most of the energy still slipped away. Doors and windows with low tightness not only save energy and reduce consumption, but also have poor sound insulation effect. The sound insulation of holes and gaps is also related to the wavelength or frequency of the incident sound wave, because the higher the frequency, the shorter the wavelength. Therefore, even if the gap is very small, it will be unfavorable to the sound insulation of high-frequency sound.

Door and window sealing strip is a kind of sealing piece mainly suitable for plastic steel doors and windows, aluminum alloy doors and windows, wooden doors and windows and other architectural decorative doors and windows. Plastic steel door and window sealing strips on the market are generally extruded from PVC, modified PVC, EPDM, elastomer sealing strips (including TPV, TPE, TPR and SEBS) and silica gel. The sealing strips of doors and windows are divided into glass sealing strips (rubber sealing strips), door leaf sealing strips and wool sealing strips. Glass sealing strip is used for sealing between glass, door leaf and door frame.

At present, steel, aluminum alloy and plastic doors and windows are generally used to install the seal between glass and door and window frame and leaf. Plastic seals are generally used to install the seal between glass and door and window frame and leaf. Rubber and plastic sealing strips are usually made of modified PVC materials.

Wind noise is caused by the gap between the air and the vehicle during driving, the sound generated by angular friction, the vehicle door, front engine cover and trunk, and the wind noise with reduced gap. Article car sealing after the car has been tested by rain all summer, timely check whether the car owner's sealing strip has hardened, deteriorated and damaged, and whether it has been replaced in time, The following suggestions should be paid attention to when replacing the automobile sealing strip!
