  • EXPANDABLE POLYSTYRENE BEAD WITH SUPERIOR ADIABATIC AND FLAMEPROOF EFFECTS AND METHOD OF PRODUCING THE SAME
    Publication number: 20100204350
    Abstract: Disclosed herein is an expandable polystyrene bead having improved adiabaticity and flame-retardance and a method of producing the expandable polystyrene bead. The expandable polystyrene bead comprises 10 to 60 wt % of a flame retardant which is made of one or more selected from among metal or nonmetal oxides, metal or nonmetal hydroxides, silicates, borates and carbonates, having a particle size of 150 ?m. Expanded polystyrene foam having improved adiabaticity and flame-retardance can be obtained using the expandable polystyrene bead. A thin flame-retardant thermal insulator including the expanded polystyrene foam can be widely used in various fire-related fields.
