摘要： PROBLEM TO BE SOLVED: To provide a polystyrene resin extrusion form heat insulator not almost discharging an organic volatile component during curing or storing after manufacturing or when used as a building material, by reducing the volatile component to be discharged from a foamable melt resin mixture and the volatile component to be discharged from an obtained extrusion foam heat insulator at an extrusion foaming time, and hence improving a working environment at the extrusion foaming time, and to provide a method for manufacturing the polystyrene resin extrusion foam heat insulator containing a small content of the organic volatile component. SOLUTION: The polystyrene resin extrusion form heat insulator has a thickness obtained by kneading the polystyrene resin melt by heating with a foaming agent and then extruding by an extruder of 5 mm or more, a density of 20 to 120 kg/m3, and an open cell foam fraction of 50% or less. A total content of the four types of organic volatile components of toluene, ethylbenzene, styrenemonomer and xylene is less than 400 ppm.

摘要： PURPOSE: To reduce shrink characteristics to enhance a dimensional stability and to raise a compression strength and a resistance to repeated compression by a method wherein an average foam diameter in a thickness direction is determined to a specific value in a specific ratio to each of an average foam diameter in a width direction and an average foam diameter in an extrusion direction. CONSTITUTION: An average foam diameter in a thickness direction is determined to 0.65-1.00mm to be 1.0-1.25 times an average foam diameter in a width direction and 0.85-1.1 times an average foam diameter in an extrusion direction. For a specific foam structure, a foaming agent is selected out of a low-boiling hydrocarbon, a low-boiling halogenated hydrocarbon, a low-boiling halogenated carbon, and the mixture of these. A resin is supplied from a material supply port 2 of an extruder 1 and kneaded under heat by a screw 3. The foaming agent is injected from a foaming agent injection port 4. The melt gel of the foaming agent is once extruded into an accumulator 5, thereafter being extruded from a die 9 to a condition under atmospheric pressure to form a planar foam 10.
