Product Name heat pad Country of Origin China Specifications HZ-GHP-0030001 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. How do you re-use the pad? Once the pad has given off all of its heat it will remain in its crystallized state until it is recharged. This is accomplished by placing the crystallized pad in boiling water for 5 to 10 minutes (depending upon the size of the pad) until all of the crystals are melted. Once completely liquefied, remove the pad from the water and store it until it is required. The pad should remain liquid as it cools. If crystals form as the pad cools it has not been boiled long enough. Place the pad in boiling water again until all the crystals have dissolved and the pad is completely clear. How long does the heat last? The pad will be very hot for the first 30 minutes and then will gradually cool down. How many times can the pad be used? There is no limit as to the number of times a pad can be used.
