Abstract

PURPOSE: To prevent the deposition of decomposition residue to the inner walls of extrusion die, in the extrusion molding of a thermoplastic resin using an azodicarboxylic acid amide as blowing agent, by adding fine powder of inorganic material to the resin.
CONSTITUTION: A composition composed of (A) a thermoplastic resin such as polypropylene, etc., (B) azodicarboxylic acid amide as blowing agent, and (C) 0.05W1 wt%, based on the resin, of inorganic powder having particle diameter of 5W50 mμ, such as silica, titanium white, etc., is extrusion molded to obtain a thermoplastic resin foamed article.
