Abstract:
1. A composition comprising, based on the total weight of the composition: from 20 to 90 wt. % of a polyester component comprising a poly(alkylene terephthalate); from 5 to 35 wt. % of wherein R 1 and R 2 are identical or different and are H, C 1 -C 6 alkyl, linear or branched, or C 6 -C 10 aryl; and R 3 is C 1 -C 10 , alkylene, linear or branched, C 6 -C 10 arylene, C 7 -C 11 alkylarylene, or C 7 -C 11 arylalkylene; M is an alkaline earth metal, alkali metal, Al, Ti, Zn, Fe, or boron; m is 1, 2, 3 or 4; n is 1, 2, or 3; and x is 1 or 2; from 1 to 25 wt. % of a melamine polyphosphate, melamine cyanurate, melamine pyrophosphate, and/or melamine phosphate; from 0 to 30 weight percent of other polymers, based on the total weight of polymers in the composition; from greater than zero to 50 wt. % of a glass fiber having a non-circular cross-section; and from 0 to 5 wt. % of an additive selected from the group consisting of a mold release agent, an antioxidant, a nucleating agent, a thermal stabilizer, an anti-drip agent, a flow-promoting additive, a chain extender, a platy filler, and a UV stabilizer; wherein the components have a combined total weight of 100 wt. %; wherein a molded article comprising the composition has a comparative tracking index that is more than 350 volts in accordance with ASTM D3638-85, UL746A, or IEC-112, 3
