1, heat-resistant performance, can work in a very low temperature environment, the lowest can reach minus 100 degrees, in the air has a very good resistance to oxidation performance, due to the molecular structure of the silica gel so that the silica gel sealing ring has a very good permeability and gas has a very good selectivity, but also because of its non-toxic odorless in many food and medical industries are used to silica gel sealing ring.
2, outstanding insulating properties is another advantage, but in the appropriate increase in the material of carbon black, nickel powder, aluminum powder and so on can make it increase the conductive properties.
3, silicone sealing ring has moisture absorption properties, moisture in the environment has the function of absorption and play a role in isolation, but poor water vapor resistance.
