POLYPROPYLENE-BASED RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a polypropylene-based resin composition compounded with calcium carbonate, capable of significantly improving flexural modulus etc.SOLUTION: A polypropylene-based resin composition is such that: the polypropylene-based resin is compounded with a surface-treated calcium carbonate; wherein, the surface-treated calcium carbonate is characterized in that: an aragonite-type calcium carbonate is surface-treated with at least one organic acid selected from the group consisting of succinic acid and benzoic acid.
