substrate with a thin layer of aluminum deposited on both sides.
It is most typically used in spacecraft multi-layer insulation (MLI).
Each layer is designed with an embossed pattern to minimize physical contact between layers.
This chokes the conduction path, reducing the overall heat transfer between layers.
Embossed Double Aluminized Polyester Film is excellent for :
- Inner-layer thermal insulation for spacecraft
- Low to mid-range temperature environments
- Cryogenic applications
Material Properties :
- Typical α / ϵ value: 3.5
- Operating temperature: -251°C to 121°C
- Thickness range: 6.4 μm
- Surface resistivity: ≤ 1.0 Ω/sq
