A composition for use in forming an article is disclosed and is particularly useful as a bezel in various applications such as headlights, watches, and clocks. The composition generally includes a polyalkylene terephthalate and/or polyester thereof, a lubricant, and a plasticizer. The polyalkylene terephthalate is selected from at least one of poly(butylene terephthalate) (PBT) and poly(ethylene terephthalate) (PET). The lubricant includes an esterification product of a first alcohol and a first acid having an aliphatic and/or an alicyclic chain of at least 20 carbon atoms and is preferably the reaction product of montanic acid and a multifunctional alcohol. The plasticizer includes an esterification product of a polyoxyalkylene alcohol and a second acid having an aliphatic and/or an alicyclic carbon chain. As one example, the plasticizer is the reaction product of montanic acid and a multifunctional alcohol and the polyoxyalkylene alcohol of the lubricant is selected from at least one of polyethylene glycol (PEG) and polypropylene glycol (PPG).
