Hi,
Some time back I did a thermal characterization of the MLB lamination
process, which also involved the determination of the conductivities of all
the materials involved. I m,easured the conuctivity of Kraft paper as
0.060+/-10% Btu/hr-ft-oF (sorry, you have to do the conversion yourself). The
interfaces between layers of Kraft paper provided contact resistances
equivalent to an added paper thickness of 0.15 mils. The specific heat was
not much of factor, so I do not have a number.
