Abstract
A polyvinyl chloride composition for powder molding includes a polyvinyl chloride (A) an amount of 100 parts by mass, a plasticizer in an amount of 110 parts by mass or more and 150 parts by mass or less, and an acrylic polymer in an amount of 4 parts by mass or more and 23 parts by mass or less. The polyvinyl chloride (A) has an average particle diameter of 50 μm or more and 500 μm or less and an average degree of polymerization of 1,350 or more. The acrylic polymer has an average particle diameter of 0.01 μm or more and 10 μm or less and contains a constitutional unit derived from a (meth) acrylic ester in an amount of 50 mass % or more.
