PTFE bellow expansion joint Features:

1.High temperature resistance, working temperature can reach 250 ℃.

2.Good low temperature resistance, good mechanical toughness; Even if the temperature dropped to - 196 ℃, it can also maintain the elongation of 5%.

3. Corrosion resistance- to most chemicals and solvents, inert, acid alkali, water and a variety of organic solvents.

4. Weather-proof, service life is longest.

5. High lubrication - the lowest friction coefficient in solid materials.

6. Inadhesion - the surface tension of the solid material is is the smallest, don't adhere to any material.

7. Non-toxic, has a physiological inertia, as artificial blood vessels and organs implanted in the body for a long time without adverse reaction.
