Document Type and Number:
WIPO Patent Application WO/2020/149038
Kind Code:
A1
Abstract:
The present invention provides: a thermoplastic foaming resin composition which enables the achievement of a lightweight molded article that has a good foam structure even a large amount of an inorganic material powder is contained therein; and a molded article which is obtained using this thermoplastic foaming resin composition. A thermoplastic foaming resin composition which contains at least a thermoplastic resin, an inorganic material powder and a chemical foaming agent, and which is configured such that the thermoplastic resin contains a polypropylene (B) having no long-chain branching and a polypropylene (A) having a long-chain branching structure at a mass ratio of from 80:20 to 98:2. A foam molded article obtained from this thermoplastic foaming resin composition is lightweight and has a good foam structure, while exhibiting excellent physical properties such as surface properties and strength.
