Abstract: The invention relates to expandable polystyrene particles which contain foaming agents and are coated with 0.01 to 0.5 wt. % of a waterproofing agent which melts above 10 DEG C and has an average particle size of less than 100 mu m. The particles are processed to form moulded foam structures with a reduced water absorption capacity.

Abstract: Expandable styrene bead polymers (XPS) with low water absorption, obtd. by known methods of suspension polymerisation from styrene, opt. with olefinic comonomers, followed by working up, drying and coating the XPS beads. The coating consists of a mixt. of 10-95 wt.% glyceryl tristearate (GTS), 0-90 wt.% zinc stearate (ZnSt), 0-90 wt.% glyceryl monostearate (GMSR) and 5-50 wt.% (based on the wt. of the coating) of at least one hydrophobic silicate.
