Silver Teflon® FEP film is suitable for use as a single-layer Flexible Optical Solar Reflector (FOSR). It is ideal for short-duration missions with operating temperatures ranging from -150°C to 125°C. This FOSR features an SiO₂ coating to mitigate atomic oxygen (AO) erosion, followed by an electrically conductive Indium Tin Oxide (ITO) coating to control spacecraft surface charging.
