Aluminized White Kapton® Film

Since 1985 Dunmore Aerospace has been providing material solutions for the space industry. Our aluminized white Kapton® film is constructed of white Kapton® film with an aluminum coating on one side. The white polyimide film side provides similar optical properties to other white coatings and tapes. The material is typically used for the outer layer of multi-layer insulation blankets. The combination of the two surfaces provides a cold sink temperature in environments with sun impingement while reducing infrared radiation losses internal to the MLI blanket.

Reasons to Choose Metallized White Kapton® Film

Aluminized white Kapton® film plays an important role in our portfolio of MLI blanket materials. The film has similar emissivity values to silver coated Teflon™ film. While it does not provide a mirror like surface, it does have moderate absorptance properties. The advantage of white Kapton® film is the stability for cold and high temperature environments. Aluminized white polyimide film has a maximum operating temperature that is 150°C greater than silver Teflon™ film, which is ideal for hot environments like planetary surfaces.

For conditions where significant environmental degradation due to atomic oxygen is expected or you need to mitigate electrostatic discharge events, our ITO coated aluminized white Kapton® film is an ideal choice.

Metallized white Kapton® film is an excellent choice for:

Medium absorptance and high emissivity applications
Moderately low to high temperatures
An alternative to white paints and coatings
