Patent ID: 8586183

Claim:
A composition comprising a combination of: (a) from more than 45 to less than 93 weight percent of a crystalline or semi-crystalline thermoplastic polyester component selected from poly(butylene terephthalate), poly(ethylene terephthalate), poly(butylene terephthalate) copolymers, poly(ethylene terephthalate) copolymers, and combinations thereof; (b) from greater than 9 to less than 25 weight percent of an amorphous poly(ester-carbonate); (c) from 5 to 30 weight percent of a glass fiber; and (d) optionally, from 0.01 to 5 wt. % of an antioxidant, mold release agent, colorant, stabilizer, or a combination thereof; wherein an article having a 2 mm thickness and molded from the composition has (i) a near infrared transmission at 960 nanometers of greater than 30 percent and (ii) a Vicat softening temperature of at least 170° C., wherein an article having a 2 mm thickness and molded from the composition has a 10 percent improvement in percent transmission at 960 nanometers as compared to an article having a 2 mm thickness and molded from the same composition comprising (a) and not (b).
