Performance Requirements Of Sealing Materials

The performance of sealing materials is an important factor to ensure effective sealing. The selection of sealing materials is mainly based on the working environment of sealing elements, such as temperature, pressure, working medium and movement mode. The basic requirements for sealing materials are as follows:

1. It has certain mechanical properties, such as tensile strength, elongation, etc;

2. Proper elasticity and hardness, small compression set;

3. High and low temperature resistance, no decomposition and softening at high temperature, no hardening at low temperature;

4. Compatible with working medium, no swelling, decomposition, hardening, etc;

5. Good oxygen resistance and aging resistance, durable;

6. Wear resistance, no corrosion of metal;

7. Easy forming and low price;
