A polymer composition that can be readily melt-extruded into a shaped three-dimensional substrate (e.g., tube) and also applied with a conductive element using a laser direct structuring (“LDS”) process. In this regard, the composition contains a thermotropic liquid crystalline polymer and a laser activatable additive. The specific nature of the polymer and relative concentration of the polymer and additive are selectively controlled so that the resulting composition can possess both a relatively high melt viscosity and melt strength.
