COMPOSITE RESIN PARTICLES AND METHOD FOR PRODUCING THE SAME, FOAMABLE COMPOSITE RESIN PARTICLES, PRELIMINARILY FOAMED COMPOSITE RESIN PARTICLES, AND COMPOSITE RESIN FOAM-MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide composite resin particles which can maintain high dimensional stability without lowering moldability.SOLUTION: The composite resin particles related to the present invention contains a polypropylene resin, a styrene-acrylic copolymer resin, and a polystyrene resin. Relative to 100 pts.mass of the polypropylene resin, a total content of the styrene-acrylic copolymer resin and the polystyrene resin is 100 pts.mass or more and 300 pts.mass or less, a content of the styrene-acrylic copolymer is 1 pts.mass or more and 250 pts.mass or less, and a content of the polystyrene resin is 50 pts.mass or more and 299 pts.mass or less.
