Abstract

PURPOSE: To produce the titled foam which excels in compression characteristics and heat insulating performance and in which density distribution in the cross- section of an extruded foam sheet is uniform, by a method wherein a specified styrene polymer with which a flame retarder and a nucleating agent are blended, is used.
CONSTITUTION: About 0.5W10wt% of a flame retarder (a halogen-contg. compd. having a decomposition temp. of not higher than 250°C, e.g. tetrabromodecane) and about 0.001W3wt% of a nucleating agent (at least one member selected from an indigo cpd., a copper phthalocyanine pigment and an anthraquinone pigment) are blended with a styrene polymer contg. not more than 0.3wt% of styrene monomer and 0.5W1.5% of styrene trimer. The temperature of the resulting blend is brought to a foaming temperature (about 80W180°C). The blend is extruded from dies at a room temp. under atmospheric pressure to carry out expansion molding.
