HeatPax (tm) warmers are made up of a combination of iron, activated carbon, cellulose, vermiculite, water and salt. These ingredients are wrapped in a container that keeps any oxygen from interacting with the ingredients inside the warmer. HeatPax (tm) warmers generate heat through a chemical reaction when these ingredients are combined with air. When the warmer is unwrapped, oxygen is allowed to mingle with the ingredients inside the warmer. When the oxygen hits the iron in the warmer, it causes the iron to oxidize. The chemical reaction releases energy in the form of heat, the salt acts as a catalyst, the carbon works as a dispersant agent and the vermiculite works to insulate the warmer and prevent the heat from escaping too quickly.
How to Activate HeatPax
To activate our HeatPax (tm) Air Activated Warmers simply tear open the package and remove the HeatPax (tm). Insert the HeatPax (tm) warmer into a pocket or your footwear. Wait 10 - 15 minutes for the HeatPax (tm) warmer to heat up and enjoy comfortable warmth for hours.
Reusing HeatPax Body Warmers
Because they are air-activated HeatPax Body Warmers can be "shut off" by storing them in an airtight container. When you are ready to use them again, simply remove them from the container and wait for approximately 10 to 15 minutes. Once the Body Warmer's ingredients have again been exposed to airflow, they will begin emitting heat.
