Dynamic Sealing PTFE With Glass Fiber Back Up Ring

Dynamic sealing PTFE with glass fiber back up ring

PTFE polytetrafluoroethylene back up ring chemical properties:

Atmospheric aging resistance: radiation resistance and low permeability: long-term exposure to the 

atmosphere, the surface and performance remain unchanged.

Non-combustibility: The oxygen limit index is below 90.

Acid and alkali resistance: insoluble in strong acids, strong alkalis and organic solvents (including magic 

acid, namely fluoroantimony sulfonic acid).

Oxidation resistance: resistant to corrosion by strong oxidants.

Acidity and alkalinity: neutral

The advantages of PTFE back up ring: high temperature resistance, low temperature resistance, corrosion 

resistance, weather resistance, high lubrication, non-sticking, non-toxic
