Hi There

Before we discuss why does PTFE material play an important role in the sealing industry? Let me introduce you what is seals.

Seals are used to prevent fluid or solid particles from leaking between adjacent bonding surfaces and the intrusion of external magazines such as dust, sediment, moisture and so on. It’s widely used in National defense, Chemical, oilfield, hydraulic, mining,

Transportation etc industry. Although seals are small part in above industry, it play a very important role.

In order to make sure the seals are playing perfect role and avoid fluid or solid particles leak between adjacent bonding surfaces, also prevent dush or water etc into application. Material becomes a most importance element.

The performance of sealing material is an important factor to ensure effective sealing, select material comes from seals working environment, like working temperature, working pressure, media and movement etc. So the basic requirements as below:

1. Tensile strength/Elongation

2. Suitable elasticity and hardness, small compression permanent deformation

3. High and low temperature resistance

4. Adapt to the working medium, do not produce swelling, decomposition, hardening and so on;

5. Good oxygen resistance and aging resistance with long service lifetime.

6. Wear resistance, no corrosion of metal

7. Easy to form and process

Considering all above material performance, PTFE material has the characteristics of corrosion resistance, aging resistance, low friction coefficient, non-viscosity, wide range of temperature resistance and good elasticity, so it is very suitable for application in seals industry.
