Unsintered Extruded PTFE Tape
Design engineers most commonly use unsintered extruded ptfe tape for insulation of aircraft electronic equipment hookup wire for military and commercial uses. Engineers wrap unsintered extruded ptfe tape around a conductor and then heat sinter it to produce potent electric wires with integrity, rigidity and uniform insulation. Engineers use unsintered extruded ptfe tape to create high-speed data cables of superlative quality and with minimal signal loss.

FAQ:
Customer: Is your ptfe film sintered?
Foreverseal: Yes, we have both sintered and unsintered ptfe film.
Customer: Is PTFE material used as an insulator around electrical wiring?
Foreverseal: The benefits of PTFE as an electrical insulator are well known. The high dielectric strength and breakdown voltage of PTFE allows it to be used in applications where standard insulation materials would fail.
Customer: When did your company establish?
Foreverseal: Our company was established in June, 2009
