Flame retarded ABS composites were prepared by compounding deca bromodiphenyl oxide (DBDPO), and tetra bromobisphenol A (TBBPA) with antimony oxide, respectively. The effect of hindered amine typed UV absorber and benzotriazole typed UV stabilizer on the durability of bromine/antimony flame retarded ABS composites was investigated. The influence of titanium dioxide (TiO₂), as UV absorber and separator, on the durability of ABS composites was also studied. It was found that the durability of flame retarded ABS composites could be improved remarkably by the coordinative effect of hindered amine typed UV absorber , benzot riazole typed UV stabilizer , and TiO₂ .
