SiO2 Silver FEP Film
Since the silicon dioxide layer is optically clear, SiO2 silver FEP film has identical thermal optical
properties to bare silver FEP film.
As a result, the SiO2 coating adds the benefit of protection against Atomic Oxygen prevalent in the
Low Earth Orbit (LEO) environment without affecting thermal performance.
The coating thickness is minimal, giving you the needed protection with a negligible change in film mass.
The first surface of SiO2 silver coated FEP film is also electrically non-conductive.
If low electrical conductivity is a desired feature, then the SiO2 coating reinforces the high surface and
through electrical resistance of FEP film.
If your application requires a more conductive surface, an ITO layer can be added.
