aluminized polyimide film for MLI Blanket

one side /two sides aluminized Polyimide Film for MLI Blanket desgin 

aluminized polyimide film is critical mateirals to Fabricate multilayer insulation blankets.

Generally MLI Blankets tyically consist 15-40 layers of films and fabrics.Each layer film can serve

a different functional purpose in the overall MLI Blanket desgin


Aluminized polyimide film is commonly used in the following ways in an Mli blanket desgin:

cover layer
inner reflector layer
inner cover layer


Aluminized polyimide film can reflect the thermal radiation exposure away from the spacecraft.it 
ensures a stable operating temperature for your critical hardware.Aluminized polyimide film also protects

the spacecraft from other space effects.
