Hand Warmers

About this product

Activated carbon enhances the capacity of hand warmers to deliver consistent and long-lasting heat. When exposed to air, activated carbon interacts with iron powder, salt, water, and other ingredients to generate an exothermic reaction. The porous structure of Haycarb's activated carbon increases the surface area available for this reaction, thereby boosting the efficiency and duration of heat production. Our activated carbon also helps evenly distribute the heat generated, ensuring a consistent and dependable warming effect.
