Instant Hand Warmers and Instant Reusable Heat Packs work as pocket hand warmers and portable instant heat therapy.

The Science Behind Heat Wave

Heat Wave Instant Reusable Heat Packs contain non-toxic sodium acetate, a salt-water solution that can generate heat up to 130 degrees (54C). This temperature can be reached in seconds as it transforms from a liquid to solid state. When the aluminum button of the activator is clicked, it creates a physical chain reaction causing the liquid to crystallize and generates heat. The heat is generated as the liquid converts to a solid.

This process is called an exothermic reaction. The sodium acetate inside the Heat Wave packs turns to solid (“freezes”) at 130 degrees, but stays in a liquid form at room temperature. When the activator is clicked, the friction causes a few molecules to react, creating a chain reaction. The energy released in the process is therapeutic heat.

When you boil the heat pack in its solid state, the crystals melt and will eventually turn into a liquid pack. These processes can be repeated over 500 times for your continued use.
