The influence of filler concentration on electrical and thermal
conductivity is considered. It is shown that percolation conductivity
appears when ratio filler conductivity and polymer conductivity is
above 105. This case is realized for electrical conductivity.
On the contrary thermal conductivity does not have percolation threshold
because this ratio is less 105 and conductivities of polymer
matrix and of filler phase are much the same. A good agreement of
the results of calculations with experimental data for metal filled
polymer composites is stated.
