ABSTRACT:
The present invention relates to an extruded styrenic resin foam and a method for producing the same, wherein a base resin composing the extruded styrenic resin foam is a styrenic resin mixture of a styrene-(meth)acrylic ester copolymer, or a combination of a styrene-(meth)acrylic ester copolymer and polymethyl methacrylate, and a styrenic resin except the styrene-(meth)acrylic ester copolymer, and the styrenic resin mixture contains a (meth)acrylic ester component at a ratio of 4 to 45% by weight with reference to the styrenic resin mixture. The present invention provides an extruded styrenic resin foam having an apparent density of 20 to 60 kg/m3, a thickness of 10 to 150 mm, and a low thermal conductivity, and keeping excellent heat insulation performance over a long period of time and flame retardancy, even when the styrenic resin extruded foam is foamed using a blowing agent having an ozone depleting potential of 0 (zero) and a low global warming potential.
