Abstract:
1. A thermoplastic polyester composition comprising, based on the total weight of the composition: from 20 to 95 wt. % of a polyester; from 1 to 35 wt. % of a phosphorous flame retardant comprising: wherein R from 0.1 to less than 20 wt. % of a copolyetherester; from 0.1 to 5 wt. % of an anti-dripping agent; from 0 to 4.5 wt. % of a reinforcing fiber; and from 0 to 5 wt. % of an additive selected from the group consisting of a mold release agent, an antioxidant, a thermal stabilizer, a UV stabilizer, and a combination comprising one or more of the foregoing additives; wherein a 0.8 mm thick molded sample comprising the composition has a UL-94 flammability rating of V0 and a 3.2 mm thick molded sample exhibits at least one of the following properties: a tensile elongation at break of at least 4% and a tensile stress at break of at least 15 MPa, as measured in accordance with ASTM D 638, and a flexural modulus of 2,000 to 4,500 MPa, as measured in accordance with ASTM 790, and wherein melamine polyphosphate and epoxy polymer are both not present in the composition.
