Abstract
A composition of polyvinyl chloride for powder molding may include a polyvinyl chloride (A), a polyvinyl chloride (B), and a phosphate, among others. The polyvinyl chloride (A) may have an average particle diameter of 50 to 500 μm, and the polyvinyl chloride (B) may have an average particle diameter of 0.01 μm or more and less than 50 μm. An average polymerization degree of the polyvinyl chloride (A) may be 1350 or more, and the phosphate may comprise a polyoxyalkylene alkyl phosphate.
