要約
(EN)

Even when a mixture resin of virgin resin and recovered resin material is used as a resin material for molding, a stable, high-quality foam-molded article with excellent impact resistance is produced at low cost. For this, the resin material that is used includes a mixture resin of recovered resin material obtained by pulverizing a resin material solidified after melting, and virgin resin without thermal history of melting, and a foaming agent added to the mixture resin. The resin material is a mixture of a polypropylene-based resin and a polyethylene-based elastomer.
