SILICONE FLAME RETARDANT FOR THERMOPLASTIC RESIN, THERMOPLASTIC FLAME-RETARDANT RESIN COMPOSITION CONTAINING THE SAME, AND METHOD OF MANUFACTURING FLAME-RETARDANT POLYESTER RESIN STRUCTURE CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a silicone flame retardant which suppresses dripping (melt-drop) of resin at a time of combustion when dispersed into a thermoplastic resin, and exhibits high flame retardance. Ž

SOLUTION: The silicone flame retardant for a thermoplastic resin satisfies the following formulae (a)-(c) where (Tg1) represents the glass transition temperature of an organopolysiloxane having a specific structure, and (Tg2) represents a glass transition temperature after heating at 300°C for 5 hours; 50≤Tg1≤200 (a), 100≤Tg2≤250 (b), and Tg2-Tg1≤50 (c).
