  • Expandable polystyrene particles
    Patent number: 5985943
    Abstract: The 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.degree. 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.
