  • Patent number: 10590252
    Abstract: A foaming assistant material and a foam-molding method, which can achieve the functions of a nucleating agent, a dispersant, and the like sufficiently so that the cells can have smaller diameter, the mixing of foreign substances is prevented, and so on, and can produce the high-quality foam-molded article, are provided. The foaming assistant material is kneaded together with a raw material pellet and the mixture is subjected to the foam molding. The foaming assistant material is a pellet obtained by adding inorganic particles, a chemical foaming agent, and a dispersant to a dilution resin. An antioxidant may be added further to the dilution resin. In the foam-molding method, inorganic particles, a chemical foaming agent, a dispersant, and an antioxidant are added to a raw material resin at the same time in a state that the inorganic particles, the chemical foaming agent, the dispersant, and the antioxidant are mixed in advance.
