POLYSTYRENE RESIN PRE-FOAMED PARTICLE, PRODUCTION METHOD AND FOAMED MOLDED MATERIAL

摘要

PROBLEM TO BE SOLVED: To obtain a polystyrene resin foamed molded material, containing little of a volatile organic compound, and stable in dimension even used at a high temperature for a long term. SOLUTION: The polystyrene resin pre-foamed particles have many island-like indeterminated projections on the surface of the foamed particles.
