ALUMINUM POLYIMIDE FILM DETAILS
Aluminum polyimide films offer high performance and exceptional high-temperature resistance. These films are insulative on one side and conductive on the other. They combine the characteristics of polyimide film, such as heat resistance, mechanical and chemical stability, radiation resistance, and self-extinguishing properties. Additionally, they provide high thermal conductivity, reflectivity, and EMI shielding, making them ideal for demanding applications.

Satellite and Space Applications
Cable Shielding
A well-engineered cable includes many crucial independent elements. Shielding has become just as critical as other design elements. Moreover, the growing complexity of communications and control systems has increased electrical interference failures. As signals travel longer distances, interference becomes a bigger problem. Also, depending on the application, EMI, RFI, and ESI can adversely affect cables. Aluminum polyimide film acts as a shield foil, reducing signal interference effectively
