The Science Behind Heat WaveHeat 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. Product Information Recharging
- Place heat pack in rapidly boiling water until crystals completely dissolve
- Wrap heat pack in cloth to prevent burning in the event that you forget about it
- Remove heat pack and allow to cool to room temperature before next use
- If heat pack crystallizes after boiling, re-boil until crystals are completely dissolved
Warning
- Heat pack may cause skin irritation
- Liquid contents may cause burns after boiling if leaking occurs
- Use a tong style device to remove heat pack from boiling water
Caution
- Over-boiling will cause damage to the heat pack
- Do not place heat packs on your face until completely crystallized
- Insulate heat packs to control heat
- Do not microwave or store in freezer
In case of puncture or leaking
- Immediately wash area with warm water
- If contents leak onto clothes, simply wipe garment with a warm to hot cloth until contents are completely removed
