Product Description

 

High pressure flexible ptfe coupling corrugated expansion joint

Feature

The lining material PTFE is also called , 4F, the King of Plastic. PTFE has excellent acid and alkali resistance property, and it is resistant to all kinds of organic solvent, high temperature resistance, low friction coefficient, can be used for lubrication or coating. PTFE is the best quality corrosion resistant material in the world. It can working under +250℃ to -180℃ for a long time, almost resistant to all chemical medicine.
PTFE corrugated bellow expansion joint with flange
1.Flexible joint with PTFE inner
2. Have excellent dielectric and chemical corrosion-resistance;
3. Non-absorbent, non-stick, non-conductive, low coefficient and non-aging properties
4.For oil, chemicals, food, medicine, space, and other fields.

Product Features of industrial customized round white ptfe flexible plastic polyurethane bellows :

  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 the 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.
