Abstract
Expandable polystyrene-based resin particles may include a styrene-based monomer, a polysiloxane-containing macro monomer, and a coating composition having a melting point of 40° C. or greater. A coefficient of static friction of a foamed molded product, obtained by pre-expanding the expandable polystyrene-based resin particles and molding the pre-expanded expandable polystyrene-based resin particles, may be 4.0 or less. The expandable polystyrene-based resin particles may have a surface layer part that contains polysiloxane as a main component.
