Generally, car owners experience that their car is in a certain operating state, such as high-speed driving, sand and gravel roads, and downtown areas, and feel strong noise, then there may be a problem with the sealing performance of the car body, and there are many ways to solve the problem. Sealing strip is one of the more cost-effective solutions.Automobile sealing stripGenerally, there are rubber strips with uneven quality when they leave the factory. After a period of use, they will age in advance, decrease in sealing performance, and disappear. At this time, replacing the new sealing strip will affect the noise in the car. The situation has been greatly improved, and the car sealing strip is a very useful product for solving the noise problem.
In the low temperature resistance test at -40 ℃, the sealing strip is not hard and brittle, and still maintains soft and good adhesive force of the strip, showing excellent cold resistance. However, at the high temperature of 120 ℃, the weather resistance of the sealing strip is still good, and the elastic performance is maintained. The shape and function are not affected. The selection of the sealing material determines its permanent flexibility and elasticity. Through formula adjustment, improve the softness of the sealant after drying, so that it forms a good sealing layer between the sheet metal and the rubber strip. The unique high elasticity of butyl rubber ensures that the sealant is easy to peel off from the metal sheet without polluting the sheet metal.
Automobile sealing strip is mainly made of ethylene propylene diene monomer rubber (EPDM) with good elasticity, compression deformation resistance, aging resistance, ozone, chemical action, and wide operating temperature range (-40 ℃ ~ 120 ℃). It is foamed and compacted. It contains a unique metal clamp and tongue buckle, which is sturdy and durable, and is conducive to installation.
