Flame-retardant and drip-resistant polyester resin compositions include a blend of flame-retardant thermoplastic polyester base resin, and granular suspension-polymerized polytetrafluoroethylene (PTFE) resin. The polyester base resin may be inherently non-flame-retardant, in which case a sufficient amount of at least one halogenated flame retardant is present so as to impart flame-retardant properties to the composition. Alternately, the polyester base resin may include halogen atoms in its molecular structure. The suspension-polymerized PTFE is advantgeously present in an amount sufficient to impart high drip resistance to the compostions in accordance with UL Standard 94.
