PTFE (Teflon®) & PEEK Insulators | DCW

PTFE Insulator

The superior dielectric properties especially at high radar and microwave frequencies makes PTFE widely use as an insulation material. PTFE is also works in a wide temperature from –180°C to +260°C.

PTFE is capable of much higher temperatures than many other materials.

It is classed as a high performance substitute over weaker and lower melting point polyethylene.
