FOAM-MOLDED ARTICLES AND PROCESS FOR PRODUCTION THEREOF

摘要

A process for the production of foam-molded articles, which comprises: a step of preparing expandable resin particles by bringing starting resin particles (which can form expandable resin particles) into contact with an ultraviolet absorber when impregnating the starting resin particles with a blowing agent; a step of pre-expanding the expandable resin particles to form pre-expanded beads; and a step of molding the pre-expanded beads by an in-mold expansion molding method into a shape corresponding to a transport or storage container for an electrical product selected from among liquid-crystal display panels, solar cells, semiconductor wafers and semiconductor devices. The foam-molded articles obtained by the process have ultraviolet -screening properties.
