Expanded PTFE Film
Type “H” PTFE micro-porous film is made from PTFE dispersion resin and prepared by paste extruding and stretching technique. The film has excellent electric properties of low dielectric constant, low dissipation factor, stable electric signal in various range of frequency at the temperature of – 50℃ through 200℃ and can be used as dielectric material for micro-wave coaxial cable. The film is widely applied in the fields of telecommunication, tracing, warning, electronic confrontation and aviation guide devices etc. It conforms to the enterprise standard Q/GHAD 71-2008.
