Introduction to the characteristics of automotive seals

Automotive seals have the function of filling various gaps between body parts, with shock absorption, waterproofing, dustproofing, sound insulation, decoration and other functions. Improve the comfort of driving experience and protect the body.

General car owners experience their car driving in a certain state, such as high speed, sandy road, downtown, feel strong noise, then the greater possibility is that the body sealing performance has a problem. There are many ways to solve the problem, and seals are one of the more cost-effective solutions. Car seals are usually configured at the factory, and rubber strips of varying quality will age prematurely, reduce sealing performance, and disappear after a period of use. Car seals are a very useful product for solving noise problems.

As we all know, the role of car sealing strips can not only prevent objects outside the car from entering the car, but also effectively prevent rainwater from splashing into the car, so that the owner can drive normally. In addition, the sealing strip can also reduce the wind noise from the outside world when the car owner usually driving, with shock absorption, dustproof function.

What are the characteristics of car seals? Here we all come together to briefly understand.

In the low temperature test at -40℃, the sealing tape did not become hard or brittle, and still maintained the softness and good adhesion of the tape, showing excellent cold resistance. However, at a high temperature of 120, the weather resistance of the seal remained good, the elasticity was maintained and the shape and function were not affected.

The choice of material for the seal determines its softness and elasticity. By adjusting the formulation, the softness of the sealant after drying can be improved, thus forming a good sealing layer between the sheet metal and the rubber strip. The unique high elasticity of butyl rubber ensures that the sealant can be easily peeled off the sheet metal without contaminating it.

Automotive seals are mainly made of EPDM rubber with good elasticity, compression deformation resistance, aging resistance, ozone and chemical resistance, wide range of use temperature (-40℃~ 120℃), foaming, compounding and dense, it contains unique metal clips and tongue clips, durable and easy to install.

What are the precautions for car seal replacement? Here we all come together to briefly understand.

1. Before replacing the seal, you need to choose the right seal style according to your car model. Generally speaking, different seals are equipped with different car models.

2. After the sealing strip is selected, remove the old sealing strip, wipe the sealing strip periphery, and apply a protective agent before installing it.

3. When replacing the seal, one or two spouts will be left on the door. Note: Never block these drain holes to avoid water pooling in the car.
