What is PTFE?

PTFE - the specialized fluoroplastic

Polytetrafluoroethylene (PTFE) is a linear polymer with the following formula:
-[CF2-CF2]n- and a molecular weight between 105 and 107 .

PTFE is by far the most important fluoroplastic. PTFE is sold under the trademark names: Teflon ® , Dyneon TM , Fluon ®.


The exceptional properties exhibited by PTFE are the result of its chemical structure.

  • PTFE is temperature resistant between -200° and +250°C under conditions of continuous use.
  • PTFE is completely resistant to chemicals and can therefore be employed almost universally.
  • PTFE has an extremely low coefficient of friction, thus eliminating any stick/slip effect.
  • PTFE has the lowest relative permittivity and the lowest dielectric loss factor of any plastic, together with high specific transient resistance and surface resistance.
  • PTFE is extremely anti-adhesive.

PTFE can be mixed with inorganic materials such as fiberglass, bronze, graphite, carbon, or molybdenum sulfide (compounds). This can significantly alter the properties, particularly with regard to pressure resistance, thermal expansion, electrical values, and abrasion.


When processing PTFE, the following process steps are performed:

  • compression,
  • sintering, and
  • cooling.

Processing exerts a major influence on the molecular weight, crystalline structure and pore content of the molded parts and, therefore, on their quality.
