Double aluminized polyester film is constructed of a Polyethylene Terephthalate (PET) film
with a thin layer of aluminum deposited on both sides.
Double aluminized PET film is also referred to as double aluminized Mylar® film.
The material has a long and proven spaceflight heritage.
It is most commonly used as inner material in satellite MLI blankets and for cryogenic applications.
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 - 127 μm
- Surface resistivity: ≤ 1.0 Ω/sq
Double Aluminized Polyester Film Applications :
Satellite MLI
Satellite Propellant Tanks
Vacuum Test Chamber
Launch Vehicle Proulsion System
