Flame retardant composition, flame retardant resin composition using the same, molded article, and production method for producing molded article

摘要

A flame retardant composition having excellent heat resistance is provided. The flame retardant composition of the present invention comprises a triphosphate, at least one of an orthophosphate and a pyrophosphate in a group consisting of a predetermined orthophosphate, pyrophosphate, and triphosphate. The flame retardant composition is measured by ion chromatography, the orthophosphoric acid-derived orthophosphoric acid peak area is O, the pyrophosphate-derived pyrophosphoric acid peak area is P, and trilin T and O satisfy 4.0 × 10−2% ≦ T / (T + O) ≦ 95.0% when T is the peak area of triphosphate derived from an acid salt, or T and P are 1.3 × 10-2% ≦ T / (T + P) ≦ 25.0% is satisfied.
