  • How it works

    Heat Pax 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.

    Heat Pax 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.
