Aluminum Polyimide Film

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

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

Aluminum polyimide films is a high performance, high-temperature resistant polyimide film. It is produced by sputter coating or laminating the two materials together. The film is insulative on one side and conductive on the other. The film not only has the characteristics of polyimide film, such as heat resistant, mechanically and chemically stable, radiation-resistant, and self-extinguishing. It also has very high thermal conductivity, reflectivity and EMI shielding.

Aluminum Polyimide Film Applications


It is a used in a number of applications, including as a first surface mirror for multilayer insulation (MLI) blankets, EMI shielding, electromagnetic shielding tape and 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 application as thermo- regulative coatings, light reflectors, collectors of solar energy and antennas


Cable Shielding

A well-engineered cable is comprised 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.
