Product Info
Heat Pad (JF-GF-001)
What is in the pad?The pad contains water and food grade sodium acetate (a form of salt) and a stainless steel disc.How is the heat produced?Flexing the metal disc in the liquid creates a chain reaction causing the pad to crystallize. This crystallization ALWAYS occurs at a temperature of 130 degrees F / 54 C.Once activated, the pad has available to it a predetermined amount of energy. It will use this energy to increase the temperature of the pad to 130 degrees F / 54 C and use whatever is left to maintain that temperature. This ability to produce heat for a period of time is accomplished because all of the liquid does not crystallize immediately. Molecules that were not required to heat the pad to its maximum temperature will remain liquid, and crystallize as required, to maintain the maximum temperature.
