Aromatic polyester resin expanded beads, method for producing aromatic polyester resin expanded beads, and molded article

摘要

PROBLEM TO BE SOLVED: To provide an aromatic polyester resin foam particle which is light and has excellent moldability.SOLUTION: An aromatic polyester-based resin foam particle is obtained by impregnating primary foam particles of an aromatic polyester-based resin with a pressurized gas and heating the primary foam particles impregnated with the pressurized gas to foam again and has a bulk density of 0.0100-0.0199 g/cmand a sphericity of 0.7 or higher.
