Abstract

Disclosed is a thermoplastic molded vehicle light bezel including a polyester molding resin comprising a thermoplastic polyester selected from the group consisting of poly(butylene terephthalate) homopolymer, poly(butylene terephthalate) copolymer, poly(trimethylene terephthalate) homopolymer, poly(trimethylene terephthalate) copolymer and blends thereof, and sodium montanate.

Claims (11)

1 . A thermoplastic molded vehicle light bezel comprising a polyester molding resin comprising:

a) a thermoplastic polyester selected from the group consisting of poly(butylene terephthalate) homopolymer, poly(butylene terephthalate) copolymer, poly(trimethylene terephthalate) homopolymer, poly(trimethylene terephthalate) copolymer, and blends thereof, having an intrinsic viscosity of at least 0.7 dL/g; and

b) 0.01 to 0.5 weight percent of sodium montanate

wherein said weight percent is based on the total weight of said polyester molding resin.

2 . The thermoplastic molded vehicle light bezel of claim 1 wherein said polyester is poly(butylene terephthalate) homopolymer.

3 . The thermoplastic molded vehicle light bezel of claim 1 wherein said thermoplastic polyester is poly(trimethylene terephthalate) homopolymer or copolymer resin having poly(trimethylene terephthalate) repeat units and end groups, said poly(trimethylene terephthalate) resin having a cyclic dimer content of less than or equal to 1.1 wt %, as determined with nuclear magnetic resonance analysis, based on the weight of said poly(trimethylene terephthalate repeat units and said cyclic dimer; and an intrinsic viscosity of 0.9 to about 2.0 dL/g.

4 . The thermoplastic molded vehicle light bezel of claim 1 wherein said polyester is a blend of poly(butylene terephthalate) and poly(trimethylene terephthalate).

5 . The thermoplastic molded vehicle light bezel of claim 1 wherein said polyester is poly(butylene terephthalate).

6 . The thermoplastic molded vehicle light bezel of claim 1 that is selected from the group consisting of tail light bezel, head light bezel, interior light automotive light bezel.

7 . The thermoplastic molded vehicle light bezel of claim 1 further comprising at least one surface having a metal layer.

8 . The thermoplastic molded vehicle light bezel of claim 7 wherein the metal layer is selected from the group consisting of aluminum, chrome, and stainless steel.
