POLYPROPYLENE RESIN COMPOSITION FOR INJECTION EXPANSION MOLDING AND MOLDED PRODUCT THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene resin composition for injection expansion molding having good injection expansion moldability and affording an expansion molded product having uniform and fine cells at a high expansion ratio and excellent lightweight properties and to provide the expansion molded product composed of the same. SOLUTION: The polypropylene resin composition for injection expansion molding is characterized as comprising (A) a linear polypropylene resin and (B) a modified polypropylene resin exhibiting≥0.1 to <10 g/10 min melt flow rate,≥5 cN melt tension and strain curability and further containing (C) a lithium compound as a chemical foaming agent.
