Abstract: A foamed styrene resin material has a density .rho. of 0.02 to 0.008 and a melt tension of the styrene resin of 5 to 40 gf. The relation between an average cell diameter d (.rho.m) and the density .rho. is given by the expression: and a relation between a thermal conductivity .lambda. (kcal/m.cndot.h.cndot. .degree.C) and the density .rho. given by the expression: Accordingly, the foamed styrene resin material has a low thermal conductivity and excellent insulating property in spite of a low density (high expansion ratio foam) thereof.
