Abstract
A composition of polyvinyl for powder molding may include a polyvinyl chloride (A), a polyvinyl chloride (B), a plasticizer, and an alkyl phosphate. The polyvinyl chloride (A) may have an average particle diameter of 50 μm 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, the alkyl phosphate may comprise a mono-alkyl phosphate, and the number of carbon atoms of an alkyl group in the alkyl phosphate may be 5 or more.
