RECYCLED EXPANDABLE STYRENIC RESIN PARTICLE, METHOD FOR PRODUCING THE SAME AND MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a recycled expandable styrenic resin particle having a high yield at the production and excellent moldability and mechanical strength of the molded product, a method for producing the recycled expandable styrenic resin particle and a recycled expanded styrene resin molded product. SOLUTION: This recycled expandable styrenic resin particle has 0.7-1.0 ratio (Mw1/Mw2) of the weight-average molecular weight (Mw1) of a recycled styrenic resin particle to be a raw material to the weight-average molecular weight (Mw2) of the resultant recycled expandable styrenic resin particle in the recycled expandable styrenic resin particle obtained by adding a styrenic monomer to a dispersion prepared by dispersing the recycled styrenic resin particle obtained by pulverizing a used expanded styrenic resin molded product shrunk or melted by heating, etc., and subsequently carrying out polymerization and impregnation of a foaming agent. The method for producing the recycled expandable styrenic resin particle is provided and the expansion molded product uses the method for producing the recycled expandable styrenic resin particle.
