Types and uses of sealing materials:

The sealing material should meet the requirements of sealing function. Due to the different media to be sealed and the different working conditions of the equipment, different adaptability of the sealing material is required. The requirements for sealing materials are generally:

1.The material has good compactness and is not easy to leak the medium;

2.have appropriate mechanical strength and hardness;

3.Good compressibility and resilience, and small permanent deformation;

4.No softening or decomposition at high temperature, no hardening or brittle cracking at low temperature;

5.Good corrosion resistance, can work for a long time in acid, alkali, oil and other media, its volume and hardness change is small, and it does not adhere to the metal surface;

6.Small friction coefficient and good wear resistance;

7.It has the flexibility to combine with the sealing surface;

8.Good aging resistance and durability;

9.It is convenient to manufacture, cheap and easy to obtain.

Rubber is the most commonly used sealing material. In addition to rubber, graphite, polytetrafluoroethylene and various sealants are suitable for sealing materials.
