Patent ID: 7026386

Claim:
A flame-retarded plastic composition comprising: (A) styrene-based plastic material; (B) a brominated aromatic compound having a melting point from 200° C. to 260° C. in which all bromine atoms are attached to the aromatic ring; (C) a brominated aromatic compound having a melting point above 300° C. in which all bromine atoms are attached to the aromatic ring; (D) an organic compound having at least one 2,3-dibromopropyl group; and optionally (E) antimony trioxide; the proportions of components (B), (C), (D) and (E) per 100 parts by weight of the styrene-based plastic material (A) are such that the sum of (B)+(C)+(D) is 3 to 10 parts by weight in which (D) occupies 20 to 80% by weight of the sum and (C) occupies 10 to 60% by weight of the balance, and (E) is 0 to 3 parts by weight.
