Dear Peter,

there are data of thermal conductivity of polyimides:

    polyimide resin AURUM (Mitsui Toatsu Chemicals, Inc.)
    0.15 kcal/m.hr.C
    photosensitive polyimide Selectilux HTR3 (fy MERC)
    1600 J/cm.s.C
polyimide Probimide 200 Series (Ciba-Geigy Corp.)
    39x10exp(-5) cal/cm.s.C
    polyimide PYRALIN PI 2540, PI 2545 (Du Pont)
    37x10exp(-5) cal/cm.s.C

        PI 2550,2560,2562

    35x10exp(-5) cal/cm.s.C
    polyimide 7550 (Furane Products Co.)
    4x10exp(-4) cal/cm.s.C
polyimide PIQ 13 (Hitachi)
    4x10exp(-4) cal/cm.s.C

Sincerely yours
