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

1) The material density of the seal is good, and it is not easy to leak the medium;
2) The sealing material has appropriate mechanical strength and hardness;
3) The compressibility and resilience of sealing materials are good, and the permanent deformation is small;
4) The sealing material does not soften at high temperature, does not decompose, does not harden at low temperature, does not crack;
5) The sealing material has good corrosion resistance, can work for a long time in acid, alkali, oil and other media, and its volume and hardness change little, and does not adhere to the metal surface;
6) The sealing material has small friction coefficient and good wear resistance;
7) It has the flexibility to combine with the sealing surface;
8) Sealing material has good aging resistance and durability;
9) Seal materials should be easy to process and manufacture, cheap, easy to draw materials.
