▎ 摘　　要

NOVELTY - A polyolefin resin foamed material is prepared using blending resin particles by dispersion medium release method. The blending resin particles are cylinders, and have non-circle cross-section, such that the height of the column is L and longest radial length of cross-section through the center is D. The blended resin particles include polyolefin resin and infrared reflective agent. The infrared reflector is flake graphite, expanded graphite, expandable graphite, graphene and/or hollow glass beads. USE - Polyolefin resin foamed material (claimed). ADVANTAGE - The polyolefin resin foamed material has low heat conducting coefficient and heat insulating temperature. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of polyolefin resin foamed material.
