What types of automotive silicone rubber sealing strip can be divided into? The following liquid silicone products manufacturers for your detailed analysis;

Many people feel a strong noise when they are leaning against the side of the road, such as the highway, gravel road, car in the center of the city. It is likely that the valve body sealing performance problem, there are many ways to solve the problem, sealing strip is one of the cost-effective solutions.

Automotive silicone rubber sealing strip is generally configured at the factory, after a period of use, the difference in quality of the tape will appear premature aging, sealing performance decline and failure, and then replace the seal, will greatly improve the noise performance of the car. The sealing strip is very useful and solves the noise problem.

Classification according to sealing characteristics

It can be divided into weather seal (seal) and general seal (seal). The weather seal contains a hollow tube sponge foam, which has a better feature of retaining temperature and humidity. Common seals are door seal, suitcase seal, engine cover strip. And general sealing strips include windshield seals, corner window seals, and inner and outer clips.

Classification according to rubber composite structure

It can be divided into pure rubber silicone rubber sealing strip rubber sealing strip, is composed of a single rubber composition; Two composite sealing strips - made of dense rubber and foam foam, metal matrix material is usually made of dense rubber shaft direction; Three composite seals, it is made of two dense rubber (one of which is light color) and sponge rubber, usually made of a metal skeleton and reinforced fiber in a dense gel. A four-compound seal, consisting of four types of rubber compounds, is then coated with a thin protective layer over a sponge rubber surface. Liquid silica gel manufacturers feel that this further extends the service life of the sealing strip.
