PTFE Film is made from PTFE resin and prepared by compression molding, skiving and calendering. According to the post-processing method,it is divided three types of Oriented is used as capacitor medium,Semi-oriented is used as insulation of conductor,Non-oriented is used as insulation, sealing material in electric devices and instruments and anti-stick material at high temperature. It conforms to the professional standard QB/T 3627-99.
