<p><P>PROBLEM TO BE SOLVED: To provide a heat-resistant polystyrene resin laminate foamed sheet which hardly generates delamination between a heat-resistant polystyrene resin foamed sheet and a resin layer composed of a rubber-modified polystyrene resin as a base material resin. <P>SOLUTION: The heat-resistant polystyrene resin laminate foamed sheet is manufactured by laminating and bonding, with extrusion lamination, a resin layer composed of a polystyrene resin modified with a rubber having a rubber particle diameter of not more than 1.5μm as a base material resin or a resin layer composed of a polystyrene resin modified with a rubber having a rubber particle diameter of more than 1.5μm and not more than 2.5μm and a gel content of not less than 28% as a base material resin on at least one surface of a heat-resistant polystyrene resin foamed sheet composed of a copolymer of a styrene and a methacrylic acid or an acrylic acid as a base material resin. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
