Abstract: The present invention relates to a foam polystyrene-based bead. The foam polystyrene-based bead includes: a core containing a styrene-based resin, a char-generating thermoplastic resin, and an expanded inorganic material; and a skin disposed on the surface of the core, wherein the skin contains a resin of which the glass transition temperature is below around 120° C. The foam is contained in the core or skin. The core may further include a carbon filler. Foam produced from the expandable polystyrene beads is not an inherently self-extinguishing flame retardant material yet can have good non-flammability comparable to or better than that of inherently flame retardant materials (Non flammability level 3) as measured in accordance with KS F ISO 5660-1, heat insulation properties, and mechanical properties.

Abstract: A method of making flame retardant expandable polystyrene-based polymerized beads includes: mixing (a) about 70 to about 95 wt % of a styrene monomer, (b) about 1 to about 10 wt % of a char-generating thermoplastic resin, and (c) about 4 to about 29 wt % of inorganic foam particles to prepare a dispersion; and polymerizing the dispersion. The method of the present invention can eliminate further processing steps, can exhibit excellent productivity, and can allow easy control of the size of the beads.
