PROBLEM TO BE SOLVED: To provide a foam auxiliary material and a foam molding method which sufficiently exhibit a function of a nucleating agent, a dispersant and the like, achieve reduction in a diameter of air bubbles, prevention mixing of a foreign matter, and the like, and can manufacture a high-quality foamed molded article.SOLUTION: A foam auxiliary material is kneaded together with a raw material resin pellet, and is used for foam molding. The foam auxiliary material is a pellet formed by adding inorganic particles, a chemical foaming agent and a dispersant to a dilution resin. An antioxidant may be added to the dilution resin. A foam molding method includes simultaneously adding the inorganic particles, the chemical foaming agent, the dispersant, and the antioxidant to a raw material resin in the previously mixed state.SELECTED DRAWING: Figure 1 |
