FLAME RESISTANT POLYESTER RESIN COMPOSITION

摘要

The present invention relates to flame resistant polyester resin composition s comprising 30 to 90 weight percent thermoplastic polyester; 1 to 30 weight percent oligomeric aromatic phosphate ester; 1 to 25 weight percent phenolic polymer; 1 to 35 weight percent of at least one melamine flame retardant selected from melamine pyrophosphate, melamine phosphate, melamine polyphosphate, melamine cyanurate, and mixtures thereof; and optionally inorganic reinforcing agents. The present invention further relates to molde d articles or parts formed from resins comprising such flame resistant polyest er resin compositions, and the laser welded articles further produced therefrom .
