Upilex is a heat-resistant
Upilex-S, along with other polyimides Kapton HN and Kapton E, have been investigated by NASA with respect to their radiation durability for possible use in the Next Generation Space Telescope (later renamed the James Webb Space Telescope), where polymer film layer sunshields must operate at low temperatures and in the presence of cosmic rays.[3] Flexible superstrate solar cells have been directly grown on commercially available Upilex foils, which makes for lightweight solar cells with a high specific power. Micro-heating elements can be integrated on polyimide sheets, which gives it the benefit of robustness and low-power consumption required for high temperatures. Upilex membranes are not transparent because of their aromatic C-H stretching band, but this can be altered by substituting hydrogen atoms by deuterium atoms.
