Aluminum Polyimide Film

Aluminum polyimide films are metalized polyimides formed by sputtering or laminating metal aluminum, which makes it conductive on one side and insulative on the other. It has excellent heat resistance, mechanical and chemical stability and is radiation resistant.

  • Conductive on Aluminum Side
  • Excellent Heat Reflection
  • High Electrical Resistance

Aluminum polyimide films are a high performance, high-temperature resistant polyimide film. The film is insulative on one side and conductive on the other. It not only has the characteristics of polyimide film, such as heat resistance, mechanical/chemical stability, radiation resistance, and being self-extinguishing, it also has very high thermal conductivity, reflectivity and EMI shielding.

It is used in a number of applications, including as a first surface mirror for multilayer insulation (MLI) blankets, in EMI shielding, in electromagnetic shielding tape and for flexible etching wire.

Satellite and Space Applications

Metalized thin-film, such as aluminum polyimide films are one of the current objectives of space materials research towards developing new reflective materials. Such devices have wide applications as thermo-regulative coatings, light reflectors, collectors of solar energy and antennas.

Cable Shielding

A well-engineered cable consists of many crucial independent elements. Recently, shielding has become just as critical as any other design element. The growing complexity of today’s communications and control systems, coupled with the increased distances signal and control communications are required to travel, have exponentially increased electrical interference related failures. Depending on the application, cables can be adversely affected by EMI/RFI/ESI. Aluminum polyimide film can act as a shield foil for the cable reducing the effects of signal interference.
