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.

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.
