A heat retaining material comprises a mixture of about 20 to 35 % by weight of a triglyceride or a substitute therefor, incorporating an admixture of powdered minerals having a heat storage capability, or a mixture of 40 % to 90 % by weight of ethylene propylene rubber or thermoplastic polymer or elastomer or styrene based thermoplastic elastomers with the balance of the mixture being an inert filler material having heat storage capabilities, thus creating a mixture having malleable clay-like qualities, all the ingredients being substantially moisture free. This type of material is ideally suited for forming body warming devices and is particularly advantageous in that it can be heated in an oven such as a microwave oven. |
