Sealing Material

Because the medium to be sealed is different and the working premises of the equipment are different, different adaptability of the sealing material is required.


1. The sealing material has proper mechanical strength and hardness;
2. The sealing material has good density and is not easy to leak media;
3. The sealing material has good compressibility and resilience, and small permanent deformation;
4. The sealing material has good anti-erosion performance, 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;
5. The sealing material is not softened or decomposed at high temperature, nor hardened or brittle at low temperature;
6. The friction coefficient of the sealing material is small, and the wear resistance is good;
7. The sealing material has the flexibility to combine with the sealing surface;
8. Convenient processing and manufacturing of sealing materials, cheap price, easy to get materials.
9. The sealing material has good aging resistance and is durable;
Rubber is the most commonly used sealing material. In addition to rubber, graphite, PTFE, and various sealants are suitable for sealing materials.
