Abstract: The present invention is directed to compositions comprising carbon black and expanded graphite as well as shaped articles and coatings for substrates comprising the compositions. The present invention also relates to the use thereof and methods for reducing electrical resistivity and providing electromagnetic interference shielding as well as thermal conductivity. The compositions of the invention allow for high electrical conductivity, EMI shielding performance as well as thermal conductivity without compromising rheological properties like fluidity or viscosity, for example measured as the melt flow rate, or mechanical properties such as, impact resistance, tensile strength or elongation at break.
