Publication number: 20050256234Abstract: A flame retardant composition includes, as essential components having two specified types of phosphate compounds; silicon dioxide or metal oxides; and at least one member selected from among higher aliphatic carboxylic acids, metal salts of higher aliphatic carboxylic acid, higher fatty acid amide compounds, and esters between mono- or polyhydric alcohols and higher aliphatic carboxylic acids. This flame retarder composition is free from secondary agglomeration, and does not need incorporation of a halogenated flame retarder that when blended in a synthetic resin, releases harmful gas at combustion. The flame retardant composition enables imparting flame retardant properties to synthetic resins with the use of a small amount of flame retarder.Type: ApplicationFiled: June 11, 2003Publication date: November 17, 2005Applicant: ASAHI DENKA CO., LTDInventors: Haruki Kurumatani, Akihiro Yamaki, Ryoji Kimura
