Document Type and Number:
Japanese Patent JP3359858
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a novel resin foamed body and a laminated foamed body which enable economical production of a food container, or the like being excellent in thermal stability, thermal insulation, oil resistance, impact resistance, or the like, and a foamed molding using the same. SOLUTION: A resin foamed body is obtained by foaming a resin composition containing (a) a rubber-modified styrene resin having a dispersed particle shape of a single occlusion type in which a rubbery polymer including a single uniform phase comprising a styrene-based resin is dispersed in a styrene-based continuous phase and including a copolymer of at least one selected from an unsaturated carboxylic acid, an unsaturated carboxylate and vinyl acetate with ethylene and (b) a propylene resin, a weight ratio of (a)/(b) being in the range between 50/50-95/5. A laminated foamed body is obtained by laminating a non-foamed resin layer on one side or both sides of the resin foamed body. A foamed molding is obtained by heat forming of a resin foamed body or a laminated foamed body.
