解温度を低下させて好ましくない。[0003] However, there has not been found any composition in which an organic foaming agent is treated with an additive to improve dispersibility, and the flowability of the foaming agent and the blocking of a molded article using the foaming agent are prevented. Focusing on the fact that the addition of the blowing agent azodicarbonamide to the inorganic powder microparticles of silica, talc, calcium silicate or the fatty acid metal salt calcium stearate, magnesium stearate, etc., is used. However, it was not preferable to use inorganic powder fine particles because of the heat generated by thickening during kneading with the resin and coarsening of bubbles at the time of foaming, and the fatty acid metal salt was used to decompose a foaming agent such as azodicarbonamide. It is not preferable because the temperature is lowered.
