Aluminum Coated Black Kapton® Film
While polyimide on its own is electrically insulative, the continuous strands of
carbon in black Kapton® film dissipate charged particles.
The aluminum coated side helps provide a continuous ground to the spacecraft.
This material is a great choice for charged orbital environments, such as geosynchronous
and low-earth orbits, where stray surface charges could harm ESD-sensitive components.
The black side of aluminum coated black polyimide film also provides
high absorptivity that is ideal for mitigating stray light when insulating optical instruments.
Aluminum coated black Kapton® film is an excellent choice for :
- Outer layer of MLI blankets
- Stray charge dissipation
- Stray light mitigation
- Low to high temperature range applications
Material Properties :
- Typical outside surface α / ϵ values: 1.1
- Operating Temperature: -250°C to 290°C
- Thickness: 25 μm
- Surface Resistivity: 105 to 10 7 Ω/sq
