Abstract: An extruded polystyrene foam is produced by performing extrusion-foaming with a styrenic resin, a flame retardant composition, and a foaming agent. The flame retardant composition includes a brominated styrene-butadiene polymer, a stabilizer, and a styrenic resin; the brominated styrene-butadiene polymer is contained in an amount of 30 to 80 wt % where the total weight of the flame retardant composition is 100 wt %; and the flame retardant composition has a TGA 5 wt % reduction temperature of 255 to 270° C. The extruded polystyrene foam has excellent thermal stability, excellent flame retardancy, and an excellent appearance.
