(Summary description)Everyone is familiar with the silicone seal ring, it is very common in our lives, then, do you know its advantages and disadvantages?

advantage:

1. It has good heat resistance and is also called high temperature resistant gasket;

2. It can also work in a very low temperature environment, the lowest can reach minus 100 degrees;

3. It has good oxidation resistance in the air;

4. Due to the molecular structure of silica gel, the silica gel sealing ring has good air permeability and good gas selectivity;

5. It is non-toxic and tasteless, and silicone seals are used in many food and medical industries.

6. Outstanding insulation performance;

7. Appropriate addition of carbon black, nickel powder, aluminum powder, etc. to the material can also increase the conductivity.

8. Moisture absorption performance, has the function of absorbing and isolating the moisture in the environment, but the water vapor resistance is poor.

Disadvantages:

1. It is not suitable to use silicone seals in a working environment with a working pressure of more than 50 pounds;

2. Although silicone rubber is compatible with most oils, compounds and solvents and has good acid and alkali resistance, it has no resistance to alkane hydrogen and aromatic oils.

3. It is not recommended to use silica gel seals in most concentrated solvents, oils, concentrated acids and diluted caustic soda solutions.

4. It is not recommended to use silicone sealing ring in the working environment where there are stretching, tearing, and strong abrasion. Usually, it is only used as a static seal under the paragraph.
