The PTFE film is formed by molding a PTFE resin, and the body is cooled and cut and rolled. The film is made of a non-oriented film, and the non-oriented film is delayed by an oriented film. Non-oriented film calendering doubling film. PTFE film is used for capacitor dielectrics, wire insulation, electrical insulation, and gaskets.

    The crystallinity is high, the molecular orientation is closely arranged, and the porosity is small, so the PTFE is greatly improved. The PTFE film is classified into a color film, an activated film, and a white film. The PTFE color film is formed by adding a certain amount of coloring agent to the PTFE resin, and the sintered PTFE turning material is rolled and oriented. Red, green and blue, yellow, purple, brown, black, orange and white thirteen colors or non-directional color film.

    PTFE color film, adding a certain amount of stains, has good electrical insulation, suitable for wire, cable, electrical insulation and classification. The polytetrafluoroethylene film is a film made of a PTFE film, a filled film, and a color film, which is activated by surface treatment. Pigments, glass fiber, carbon fiber, graphite, bronze powder filled products, after activation treatment, further improve performance, can be combined with rubber and metal, can also produce special tape to meet design requirements. Widely used in light industry, military, aerospace, petroleum and other fields.
