The basic characteristics of PTFE are that it offers a unique combination of:
- low coefficient of friction
- Excellent chemical inertness
- Non-adhesive surface
- Wide temperature range (-200 °C to +260 °C), excellent dielectric properties.

MECHANICAL PROPERTIES
Compressive strength at a given predetermined compressive strength is one of the most significant mechanical characteristics of PTFE over a wide range of service temperatures. Flexural strength, plastic memory and hardness are additional characteristics of PTFE products.
ELECTRICAL PROPERTIES
PTFE products have excellent dielectric performance over a wide range of frequencies and temperatures. Dielectric strength changes with thickness and decreases with increasing frequency, without substantial alterations up to 300 °C.
CHEMICAL INERTNESS
PTFE is practically inert to all chemicals except some alkali metals, e.g. chlorotrifluoride and basic fluorine at high temperatures and pressures.
THERMAL PROPERTIES
PTFE is considered one of the most thermally stable materials. Up to an operating temperature of 260 °C, PTFE does not change its physical and molecular properties.
