Abstract

PURPOSE:To obtain the title foam being light in wt. and having excellent heat insulating property and bending strength, by pressing a vaporizable foaming agent into a polystyrene resin wherein a plasticizer is added and carrying out the extrusion foaming of the mixture. CONSTITUTION:A compsn. is obtd. by compounding 100pts.wt. polystyrene resin whose specific viscosity(measured in a toluene soln. of 100mg/100cc at 30 deg.C) is 0.6-1.6, 0.7-5pts.wt. plasticizer whose viscosity is 5-100cst at 40 deg.C (e.g., liq. paraffin) and 0.05-5pts.wt. nucleating agent (e.g. talc). Then, 0.1-0.3mol. of a vaporizable foaming agent (e.g., dichlorodifluoromethane) per 100g polystyrene resin are pressed into his compsn. and the extrusion foaming of the mixture is carried out to obtain a polystyrene resin foam whose foam density is 15-28kg/m<3>, average cell diameter is 0.3-0.6mm and thickness is 15-100mm.
