Which working conditions are not suitable for silicone seals?

Silicone seals are widely used in many industries.If you are a regular user or buyer of silicone seals, have you ever considered that silicone seals are not suitable for certain occasions?Today, let's take a look at which working conditions are not suitable for silicone seals.

Silicone seal have numerous advantages, such as resistance to low temperature, low temperature resistant performance can make the silicone seal work under low temperature environment, the minimum can achieve - 70 ℃, in the air has good resistance to oxidation and ozone resistance, because the molecular structure of the silica gel silica gel seal ring has good air permeability, and gas also has the very good selectivity;Because of the characteristics of non-toxic and tasteless silicone seal ring, so in many food and medical industry have been used to silicone seal ring.

Which working conditions are not suitable for silicone seals?

1. Silica gel seal ring has hygroscopic property, which can absorb water in the environment and insulate it, but has poor resistance to water vapor.

2. Silicone seals are not suitable for working under working pressure of more than 50 pounds;

3. Although the silicone seal ring has good acid and alkaline resistance, it has little resistance to alkali-hydrogen and aromatic oils.

4. Silicone seals are not recommended for use in most concentrated solvents, oils, concentrated acids and diluted caustic soda solutions.

5. It is not recommended to use silicone sealing rings where there are stretching, tearing, strong wear and other conditions in the working environment.

In the above working environment, it is not recommended to use the silicone seal ring. Although the silicone seal ring has many excellent performance characteristics, the silicone seal ring also has its short board, we should try to avoid it in use, so as to achieve the maximum use efficiency of the seal ring.
