METHOD FOR PRODUCING FOAMED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a foamed product which suppresses the occurrence of silver streaks and dimples and is excellent in surface appearance.SOLUTION: A propylene-based resin composition comprising: a propylene polymer (A) or a mixture (A") of propylene polymers composed of the propylene polymer (A) and a propylene homopolymer (A'); an organic nucleation agent (B); and a forming agent (C) is ejected in a cavity filled with gas and pressurized. The cavity volume is expanded 1 to 10 minutes after ejecting the propylene-based resin composition to foam the propylene-based resin composition.
