Publication number: 20130172455Abstract: This polypropylene resin composition is characterized by containing the following per 100 mass parts of a polypropylene resin: 0.06 to 0.1 mass parts of a specific aromatic metal phosphate, 0.015 to 0.02 mass parts of a specific aromatic triamide compound, and 0.015 to 0.03 mass parts of magnesium hydroxide. This polypropylene resin composition makes it possible to increase the transparency and physical strength of a polypropylene resin with only small amounts of a nucleator and transparentization agent added. The reduction in the amounts of additives also increases resistance to leaching and makes molded articles more sanitary.Type: ApplicationFiled: November 8, 2011Publication date: July 4, 2013Applicant: ADEKA CORPORATIONInventors: Naoko Tanji, Mohamed Sidqi
