The ReHeater Heat Pack contains sodium acetate which is a form of salt. By flexing the patented stainless steel trigger within the sealed pack causes a single molecule of liquid to crystallize which starts a chain reaction causing the entire solution to change from a liquid to a solid. This phase change causes the pack to heat to approximately 130F (82 below the boiling temperature of water, 212F). By placing the pack in water with a temperature greater than 135F (57C), the crystals are returned to a liquid state. This process can be repeated hundreds of times, provided the pack remains sealed. Over long periods of use you may find some small snowflake-like crystals that may appear inside the pack. These crystals will not affect the performance of the pack. However it is possible to eliminate them by boiling the pack for an extended period of time. To prevent flakes from forming, keep the pack in a liquid state during storage periods of two or more months.
