FLAME RETARDANT MATERIAL, INJECTION MOLDING METHOD AND MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To obtain a flame retardant molding material which realizes higher flame retardancy than ever and which has excellent recycling properties in a system which uses a combination of a low-cost resin with good moldability such as a polystyrene-based resin and a flame retardant resin such as a polycarbonate-based resin, to provide an injection molding method and a molded article. SOLUTION: The flame retardant molding material contains a flame retardant thermoplastic resin (A) and a thermoplastic resin (B), wherein the components (A) and (B) undergo phase separation, when molded, to form a molded article outer layer containing the component (A) as a main component and a molded article inner layer containing the component (B) as a main component.
