Sealing Strip
Product introduction
Automotive sealing strips can fill various gaps and gaps between the components of the body, and have the functions of shock absorption, waterproof, Dustproof, sound insulation, decoration and other functions, improve the comfort of the driving experience and protect the car body.
Product Features
In the -40 ℃ low temperature resistance test, the sealing tape does not become hard or brittle, but still maintains softness and good adhesion of the tape. Excellent cold resistance. At a high temperature of 120 °C, the weather resistance of the sealing strip is still good, and the elastic properties are maintained, and the shape and function are not affected.
The choice of the sealant material determines its permanent softness and elasticity. By adjusting the formula, the softness of the dry sealant can be improved, so that it can form a good seal between the sheet metal and the rubber strip. layer, the unique high elasticity of butyl rubber, ensures that the sealant can be easily peeled from the metal sheet metal without contaminating the sheet metal.
Automotive sealing strips are mainly made of EPDM with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical action, and a wide operating temperature range (-40℃~+120℃). Rubber (EPDM) rubber foamed and densely compounded, with unique metal clamps and tongue buckles, which are durable and easy to install.
Classified by section shape
It can be divided into solid core products (round, square, flat section shape), hollow products and metal-rubber composite products. Among them, metal-rubber composite sealing strip accounts for more than 60%. The cross-section design is critical for rubber seals. The first is the shape and size design of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force. The length and thickness of the lip should be appropriate. Too thick or too long will make the glass lift resistance too large. If too thin or too short, the glass will not be well guided and sealed, resulting in vibration, noise and rain leakage. The shape and size of the bottom of the section are designed. There are protrusions on the section of the steel groove of the window. Its function is to assemble the guide groove. Therefore, the bottom of the guide groove section should be designed with a corresponding structure, which is easy to install and can use the elasticity of the sealing strip itself. It is attached to the steel guide groove to prevent it from coming out; the last is the shape and size of the outer edge. In order to improve the appearance, the outer surface of the guide groove should be closely fitted with the body.
Classified by sealing characteristics
It can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). Among them, the weather sealing strip has a hollow sponge tube, which has a better temperature and humidity retention function. Common weather sealing strips include door frame sealing strips, trunk sealing strips, engine cover strips, etc. Commonly used general sealing strips include front and rear wind window sealing strips, corner window sealing strips, inner and outer strips, etc.
Classified by material varieties
It can be divided into rubber sealing strip; plastic sealing strip; thermoplastic elastomer sealing strip.
Classified according to the surface treatment status
Part of the sealing strip surface after additional treatment, can be divided into flocking type sealing strips; surface coating sealing strips; fabric-applied sealing strips
