Double Aluminized Kapton® Film
DuPont™ Kapton® film is a low to high temperature range material.
By aluminum coating both sides, most of the incident heat radiated to either surface is reflected.
A typical MLI blanket consists of 15 to 40 layers of double aluminized polyimide film separated
rom one another by a netting material. Since Kapton® film can withstand higher temperatures
than polyester-based products and offers better UV protection, it may be used as the space-facing layer.
Double aluminum polyimide film is also the preferred choice for the structure facing side
of an MLI blanket due to its flame retardent properties.
Double Aluminized Kapton® film is an excellent choice for :
- Space side, inner layer, and structure side of MLI blankets
- Low to high temperature applications
- Excellent radiation resistance
Material Properties :
