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 ~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.

Date Nov. 20, 1997The present invention relates to expandable polystyrene beads containing blowing agent which are coated with from 0.01 to 0.5% by weight of a hydrophobicizing agent which melts above 25 DEG C. and has a mean particle size of less than 100 mu m. The beads can be converted into foam moldings having reduced water absorption capacity.
