ITO Coated Silver FEP Film
The ITO layer of ITO coated silver Teflon™ film is optically clear and electrically conductive.
It provides protection from electrostatic charge buildup and atomic oxygen while maintaining
the thermo-optical properties of Ag FEP film. This combination of properties is particularly
useful in applications where electrostatic discharge poses a hazard to electrically sensitive
components like electronics and instrumentation. Missions flown to the ISS in particular usually
have strict grounding requirements and must function in the AO and contamination
heavy environment of the low-orbiting ISS.
At 2,500 Ω/sq. on the exterior surface, ITO coated silver Teflon film provides similar
electrical resistivity as the interior Inconel layer protecting the silver film. The MLI film
can be grounded using mechanical lugs though tape may be difficult to keep adhered to the ITO layer.
Perforations or other features can be added to the film while maintaining electrical conductivity
so long as the ITO layer is continuous.
