Abstract
A phase change material (PCM) is useful for thermal management in various applications such as automotive, building, packaging, garments, and footwear, and in devices such as wires and cables. The cable described herein comprises a core and a PCM layer surrounding the core. The PCM layer comprises a PCM composition, which in turn comprises a 1,3-propanediol fatty acid ester. The core consists of a yarn, strand or wire made of a natural or synthetic polymeric material or a metal.
Claims15
