In which environments can the rubber sealing ring not be used?

There are many advantages of rubber sealing ring. First of all, its high temperature resistance can work in a very low temperature environment, and it can be less than minus 100 degrees. It has good resistance to air oxidation and active oxygen in the air. , Because the molecular formula of the silicone material makes the rubber sealing ring have good air permeability and good selectivity for the gas, and because it is non-toxic and odorless, it is widely used in many food and medical industries. lock up.

Some rubber sealing rings are added with unique seasonings. Special rubber sealing rings also have the properties of radiation resistance, flame resistance, acid and alkali resistance, but the disadvantage of silicone silicone is that the performance of mechanical equipment is weak. It is not recommended to use rubber sealing ring in the environment of stretching, pulling and strong damage. Usually, it is only used as packing seal under payment application.

The insulating layer performance of the rubber sealing ring is another good point, but moderately increasing carbon black, nickel powder, alumina powder, etc. in the raw materials can improve the electrical conductivity. The rubber sealing ring also has hygroscopic properties, which can digest and absorb water in the environment and have the function of blocking, but the resistance to water vapor is poor. Talking about the good trend of so many expensive silicone rubber sealing rings. Its shortcomings are also more prominent, and its shortcomings determine the environment in which it is not suitable to use rubber sealing rings.

Rubber seals are not suitable for use in working environments where the pressure exceeds 50 pounds. Although silicone is compatible with most oils, chemicals and organic solvents and has good corrosion resistance, it is suitable for alkane hydrogen and aromatics. The oil has no resistance. It is also not recommended to use rubber sealing rings in most organic solvents, refined oils, concentrated acids and caustic soda solutions after dilution.
