ABSTRACT:
A thermoplastic, moldable, non-exuding phase change material in the form of a composite useful for thermal energy storage. The composite is preferably a solidified melt mixture of a polyolefin resin, and ethylene copolymer, silica particles and a fatty acid, fatty acid ester, primary alcohol or hydrocarbon phase change material. For a microwave heating capability, a microwave absorbing additive may be added as a fifth major ingredient. The composite can be formed into a variety of configurations such as pellets, sheets, rods, tubes, plugs for hollow core cement blocks, films, and fibers, all for thermal energy storage uses.
