Polyimide film Your location:home > Products

  Polyimide film is synthesized by polymerizing PMDA and ODA in strong polar solvents through the process of forming film and imine treatment at high temperature, which possesses excellent physical, chemical, and electrical properties, atomic radiation resistant, solvent resistant, low and high temperature resistant. It performs successfully in the wide range of temperature as low as -269℃ and as high as 260℃.It is widely used for wrapping of magnet wire and cable, slot liner insulation, interlayer insulation in Motor, transformer and the substrates or overlay of flexible printed circuits board.

  Thickness:0.0125, 0.025,0.05,0.075,0.10,0.125.
  Width: 500,520,1000 (Customers special requirements on specifications could be negotiated case by case)
