Abstract

A foam molding material made by foam molding a foaming polystyrene system plastic powder by polymerizing cross-linkable monomer and styrene monomer on the surface of a polystyrene system plastic powder to form a surface layer, and by impregnating an easily volatile foaming agent into the surface layer. The number of cavities existing in the range of 100 to 500 μm of a longer diameter and 10 to 100 μm of a shorter diameter on the cross section of the foam molding material is less than 5 pieces per 1 cm<SP>2</SP>.
