Ptfe Films

Empowered with a team of assiduous personnel we are immersed in supplying a huge spectrum of PTFE Films in Tianjin China. Expanded PTFE film is an expanded low-density PTFE film designed for microwave and coaxial cable applications.A The low dielectric constant and low loss characteristics of this film help to retain signal strength in high performance cable constructions.A This film is easily applied with standard industry wrapping equipment and is typically shielded or jacketed to protect the dielectric qualities of the film.
