摘要： A halogen-free, flame retardant polyester composition comprises, based on the total composition, (a) A poly(ethylene terephthalate) with a molecular weight of at least 50,000 or a blend of poly(ethylene terephthalate) with another polyester, taking into account that the ratio poly(ethylene terephthalate)/other polyester should be at least 55/45. (b) A combination of at least one N-containing compound, selected from the group of triazine, guanidine, or (iso)cyanurate compounds, and at least one P-containing compound, selected from the group of BPA-diphosphates or phosphoramides with the proviso that the ratio of the total amount of P- and N-containing compounds over the total polyester amount should be between 0.3 and 0.6 and the ratio of the P-containing compound over the N-containing compound should be higher than 0.8. (c) An anti-dripping agent in an amount of 0.01-2 weight percent of the total composition. (d) A reinforcing filler in an amount of 0-40 weight percent of the total composition.
