FLAME-RETARDANT STYRENE RESIN COMPOSITION

摘要

Disclosed is a flame-retardant styrene resin composition. The composition comprises 100 parts by weight of a styrene resin, 0.5 to 10 parts by weight of a brominated flame-retarder which has a bromine content of 60% by weight or higher, and 0.005 to 0.5 part by weight of urea, thiourea or an N-substituted derivative thereof. By using an urea compound concomitantly, the amount of the brominated frame-retarder required for achieving a desired flame retardancy level can be reduced.
