<p>The present invention relates to thermoplastic expandable resin particles on which a nonflammable and insulating film is formed. A nonflammable and insulating film is formed on a surface layer of expandable resin particles by heating a nonflammable and insulating powder comprising a metal, a nonmetal, a metal oxide, a metal hydroxide, and a nonmetal mineral with a diameter of 1-70 mum at 50-300 °C, spraying the heated powder on the surface layer of resin particles before expanding and expanded particles so as to impregnate the powder through compression stirring, and bond coating the same, and a nonflammable and insulating molded product is prepared by providing the same.</p> |
