Abstract
Molded articles are disclosed having a complex three-dimensional shape. In one embodiment, the molded articles comprise tubular members formed through blow molding that have multiple linear sections separated by curved sections. The curved sections can include multiple angular displacements in multiple planes. The tubular members are molded from a polymer composition containing a high temperature polymer, such as a polymer having a melting point of greater than about 280° C., such as greater than about 290° C. In one embodiment, the tubular member includes at least three angular displacements of from about 60° to about 120°, such as from about 70° to about 110°.
