Abstract
Rigid polystyrene foams contain thermally treated non-graphitic anthracite coke particles. Such athermanous materials permit a more energy-efficient grinding process, wherein the ground particles are yielded in the desired platelet form and these ground particles also disperse well in a polystyrene matrix. Therefore the rigid polystyrene foams containing the anthracite coke particles have a density of less than 40 kg/m3 and a thermal conductivity of less than 40 mW/m·K which provides desired thermal insulation properties.
