PROBLEM TO BE SOLVED: To provide a polystyrene-based resin-extruded foam plate that has small thermal conductivity, high heat insulating properties for a long period, high oxygen index, and excellent flame retardance, even if an earth-friendly foaming agent or the like is used.SOLUTION: A polystyrene-based resin-extruded foam plate contains graphite and a flame retardant, wherein: the graphite is a spheroidized graphite; and the content of the graphite is 1 to 10 pts.wt. based on 100 pts.wt. of a base material resin configuring the polystyrene-based resin-extruded foam plate. |
