The invention provides processes for making a coaxial device by simultaneously extruding a polymer encapsulation layer defining a hollowed area and filling the hollowed area with PCM composition in liquid form. The invention is useful for thermal management in a variety of applications in such as, for example, automotive, building, packaging, garments, and footwear.
