Chemical Resistance PTFE Membrane

The PTFE film is molded, sintered, cooled into a blank by a suspension PTFE resin, and then subjected to turning and calendering. The turned film is a non-oriented film, and the non-oriented film is calendered to form an oriented film. PTFE film is used in capacitor dielectrics for wire insulation, electrical instrument insulation, and gaskets. PTFE film is divided into PTFE color film, polytetrafluoroethylene activated film and F46 (FEP) film....
