PTFE resin is first molded, sintered and cooled to be working billet, then skived and calendered to PTFE film, PTFE film can be used for insulation liner, sleeve, low frictional materials and chemical corrosion resistant materials. Its properties cannot be attacked by frequency and temperature, it can be used in the temperature range of -180℃~+260℃.
