Abstract: A styrene resin extruded foam includes a styrene resin, a flame retarder, a hydrofluoroolefin, an alcohol, and at least one selected from the group consisting of a saturated hydrocarbon having 3 to 5 carbon atoms, dimethyl ether, and alkyl chloride. An amount of the flame retarder is 0.5 to 8.0 parts by weight relative to 100 parts by weight of the styrene resin. The styrene resin extruded foam has an apparent density of 20 to 45 kg/m3 and a closed cell ratio of not less than 90%. An amount of the hydrofluoroolefin added is 65 to 90 mol % relative to 100 mol % in total of the hydrofluoroolefin and the alcohol which are added. An amount of the alcohol added is 10 to 35 mol % relative to 100 mol % in total of the hydrofluoroolefin and the alcohol which are added.

Abstract: A styrene resin extruded foam includes graphite and a styrene resin. The graphite is in an amount of 0.5 to 10.0 parts by weight relative to 100 parts by weight of the styrene resin. The graphite has an average particle diameter of 2.5 μm to 9 μm. A laser scattering intensity is not less than 5 {%/(mg/mL)}/wt % per unit solution concentration of the graphite as measured by a particular method.

Abstract: An extruded styrenic resin foam may include 100 parts by weight of a styrenic resin; 0.5 to 8.0 parts by weight of a flame retardant; 1.0 to 5.0 parts by weight of graphite; a saturated hydrocarbon having 3 to 5 carbon atoms; and a hydrofluoroolefin. 1 kg of the extruded styrenic resin foam includes the hydrofluoroolefin in an amount of 0.05 to 0.40 mol, and the saturated hydrocarbon in an amount of 0.10 to 0.40 mol, a total amount of the saturated hydrocarbon and the hydrofluoroolefin being 0.30 to 0.50 mol relative to 1 kg of the extruded styrenic resin foam.
