Aluminized Kapton® Polyimide Film

2013-06-24

KGK is a leading manufacturer of aluminized Kapton® film, a widely used spacecraft material. There are many technical challenges associated with developing a spacecraft. The harsh space environment requires technical materials that function as a passive thermal management system.

 

 

Depending on the mission, a spacecraft can experience moderate to high heat conditions. Aluminized polyimide film reflects the thermal radiation exposure away from the spacecraft. This ensures a stable operating temperature for your critical hardware. Aluminized DuPont™ Kapton® film also protects the spacecraft from other space effects.
 

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.

Details

Aluminum polyimide films are high-performance, high-temperature resistant polyimide films. 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.

 

Aluminum Polyimide Film Applications

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 shielding foil for the cable reducing the effects of signal interference.
