Abstract
In this research is improvement of physical and mechanical properties by
solvent the styropore with labaritory benzene (C6H6) and then mixing with
different weighted ratio of carbon particles ( 2.5 , 7.5 , 15 , 30 and 60 )% at size less from 63ìm were added to dissolved styropore to proper samples were applied to many tests of dielectric constant, hardness, thermal conductivity.
