The basic characteristic of PTFE is a unique combination of the features listed below.
In the wide temperature range, the compressive strength of a predetermined pressure value is one of the most important mechanical properties of PTFE. Flexibility, plastic memory and hardness are other characteristics of PTFE.
PTFE materials have excellent dielectric performance over a wide temperature and frequency range. Dielectric strength varies depending material thickness and not significant alteration on the frequency decreases up to 300 ° C.
PTFE is practically unresponsive to all chemicals, except for alkaline metals such as basic fluorine and clorofluoruro at high temperatures and pressures.
Basically PTFE is one of the most stable materials. The physical and molecular properties of PTFE up to 260 ° C are unchanged.
