What is PTFE bellows expansion joints? PTFE bellows expansion joints is made from PTFE instead of stainless steel. PTFE has super excellent chemical stability and corrosion resistance, it has the best corrosion resistance in the world. Also, PTFE has the property of excellent sealing, high lubrication, not adhesive to objects, electrical insulating and temperature resistance.


Lanphan PTFE bellows expansion joints mainly used to connect pipelines. Our PTFE bellows expansion joints owns following features:

1. High temperature resistance, working temperature can reach 250 íŠ;

2. Good low temperature resistance, good mechanical toughness; Even if the temperature dropped to - 196 íŠ, 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 the longest among plastic;

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

6. Inadhesion - the smallest surface tension in solid material, 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.
