    • A thermoplastic polyester resin composition, a pellet prepared by extruding the composition, and a housing for an electrical or electronic part molded by using the composition are provided to improve flame retardancy, mechanical properties and environmental friendliness by preventing the generation of halogenated gas. A thermoplastic polyester resin composition comprises 100 parts by weight of a polyester resin; 1-60 parts by weight of a cyclic phosphazene oligomer compound; 1-50 parts by weight of a melamine-based compound; 1-20 parts by weight of a metal inorganic compound; 0.1-5 parts by weight of a fluorinated polyolefin-based resin; and optionally 150 parts by weight or less of a filler. Preferably the cyclic phosphazene oligomer compound is represented by the formula I, wherein R1 is an alkyl group, an aryl group, an alkyl-substituted aryl group, an arylalkyl group, an alkoxy group, an aryloxy group, an amino group or a hydroxyl group; k and m is an integer of 0-10; R2 is a C6-C30 dioxyaryl group or an alkyl-substituted C6-C30 dioxyaryl group; and n has an average of 0.3-3.
    • 提供热塑性聚酯树脂组合物,通过挤出组合物制备的颗粒和通过使用该组合物模制的电气或电子部件的壳体,以通过防止产生卤化气体来改善阻燃性,机械性能和环境友好性。 热塑性聚酯树脂组合物包含100重量份的聚酯树脂; 1-60重量份环状磷腈低聚物化合物; 1-50重量份的三聚氰胺类化合物; 1-20重量份的金属无机化合物; 0.1-5重量份氟化聚烯烃类树脂; 和任选的150重量份或更少的填料。 优选地,环状磷腈低聚物化合物由式I表示,其中R 1是烷基,芳基,烷基取代的芳基,芳烷基,烷氧基,芳氧基,氨基或羟基 ; k和m是0-10的整数; R2是C6-C30二氧基芳基或烷基取代的C6-C30二氧基芳基; n平均为0.3-3。
