Abstract
PURPOSE: To manufacture a colorless foamed article having a low density and improved touch, and containing fine bubbles uniformly in the surface layer, by applying a substance which exothermally decomposes under the foaming condition of the foamable resin, to the surface of a thermoplastic resin molded article containing a decomposition-type foaming the article by heating.
CONSTITUTION: In the manufacturing of a thermoplastic resin foamed article by heating a molded article containing a decomposition-type foaming agent, the foaming is carried out in the presence of a substance which exothermally decomposes under the foaming condition of the above molded article, on the surface of said molded article. The substance to be applied to the surface of the article is pref. dinitrosopentamethylenetertramine, and it is applied e.g. by scattering the powder to the surface.
