PTFE

PTFE

The base characteristics of PTFE are the ones offering a unique combination of:

  • low coefficient of friction
  • excellent chemical inertness
  • non-adhesive surface
  • wide temperature range withstanding (–200° C to +260° C), excellent dielectric properties.
The most popular and processed materials of which Guarniflon® stock quite large quantities and owns large production capacity:
  • PTFE - G400

    Extruded tubes and rods
    Moulded tubes rods and sheets
    Skived sheets
    Skived tapes
    Finished products.
  • PTFE - G200

    Extruded tubes and rods
    Skived sheets
    Skived tapes
    Finished products.
  • PTFE - G500

    Uded tubes and rods
    Skived sheets
    Skived tapes
    Finished products.
  • PTFE - G300

    Extruded tubes and rods
    Finished products.

MECHANICAL PROPERTIES

The compressive strength at a certain predetermined compression value is one of the most significant mechanical characteristics of PTFE, in a wide range of service temperatures. Flexibility strength, plastic memory and hardness, are additional characteristics of PTFE products.

ELECTRICAL PROPERTIES

PTFE products have excellent dielectric performances in a wide range of frequencies and temperatures. The dielectric strength changes according to the thickness and decreases when the frequency increases, with no substantial alterations up to 300°C.

CHEMICAL INERTNESS

PTFE is practically inert to all chemical products, except for some alkaline metals, for example, clorotrifluoruro and for basic fluorine at high temperatures and pressures.

THERMAL PROPERTIES

PTFE is considered one of the most stable materials from the thermal point of view. Up to a service temperature of 260° C PTFE does not change its own physical and molecular properties.
