UPILEX
Encyclopedia
Upilex is a heat resistant polyimide film formed from biphenyl tetracarboxylic dianhydride (BPDA
) monomers. Its properties include dimensional stability, low water absorption and high chemical resistance. It was developed by UBE Industries
.
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, where polymer film layer sunshields must operate at low temperatures and in the presence of cosmic ray
