The thermal conductivity of Kapton at temperatures from 0.5 to 5 Kelvin is rather high for such low temperatures, κ = 4.638×10 −3 T 0.5678 W·m −1 ·K −1. [7] Kapton insulation ages poorly: an FAA study shows degradation in hot, humid environments [8] or in the presence of seawater. It was found to have very poor resistance to ...
