  PTFE Film

  Characteristics

  PTFE film is made of polyflon through green compact, sinter and skived, The film can be made into high-density film and seim-density film by means of rolling according to different ratio. PTFE film has good tensile strength, high dielectric, chemical resistant, not aging etc.

  Applications
  Lining, sealing, lubricating material and dielectric at any frequencies.Wire insulation,electricalinstrument insulation.

  Appearance

  Qualified PTFE film couldn’t have any pore,dirt,mechanical damage,buckling and conduction impurity. Surface is flat, no crack or crinkle on edge.
