FLAME RETARDANT POLYESTER RESIN COMPOSITION

摘要

Disclosed is a flame retardant polyester resin composition which is halogen free and exhibits high initial flame retardance. This flame retardant polyester resin composition is capable of maintaining adequate flame retardance even after a long-term heat aging test. Specifically disclosed is a flame retardant polyester resin composition obtained by adding an organophosphorus flame retardant (B) represented by the general formula (1) below (wherein n = 2-20) and a nitrogen compound (C) to a thermoplastic polyester resin (A) in certain ratios. This flame retardant polyester resin composition exhibits high initial flame retardance and is capable of maintaining adequate flame retardance even after a long-term heat aging test.
