Abstract
A microwave heatable composite material that comprises: a heat resistant moldable base material; a microwave heatable material dispersed in the heat resistant moldable base material; and a phase change material dispersed in the heat resistant moldable base material. The mixture of the microwave heatable material, heat resistant moldable base material, and phase change material provide a basic or core microwave heatable article layer to which one or more additional controlled heat releasing and/or heat transfer blocking layers can be combined to enhance and optimize heat therapy. In addition, the microwave heatable articles of the present invention can be used for cold therapy by lowering their temperatures in a freezer of similar cold environment.
