HODAF Factory has been manufacturing and developing self-heating heat pack for over 20 years. Customisable heat pack specifications: Pattern,Weight, Heating duration, Heating temperature.Package. Supply solutions to clients' requirements across various scenarios and applications.
Why Self-Heating Heat Pack can be warm instantly?
Self-heating Heat packs contain a mixture of iron powder, salt, water, and activated carbon,etc.,when the pack is opened, the iron reacts with oxygen in the air, this process called oxidation. This chemical reaction is exothermic, meaning it releases energy in the form of heat as the iron turns into rust. The water and salts help regulate the rate of the reaction, allowing the pack to provide heat for a longer period.
Additionally, by adjusting the size and number of breathable pores in the outer material of the heat pack, the air intake can be controlled to regulate the reaction speed, thereby adjusting the product's heating temperature and duration.
Why Choose HODAF self-heating Heat Pack?
Hodaf heat pack includes utilise reduced iron powder with a purity exceeding 98%, this powder have larger surface area exposed to air, it accelerates oxidation reactions, enabling rapid and uniform heating.For the same weight of powder, Hodaf heat pack’has shorter heat-up time,longer heating time is longer, and more stable, temperature.
Precautions for Use of Self-Heating Heat Pack
Some heat packs feature an adhesive backing that can be applied directly to the area requiring warmth. It is crucial to note that the adhesive side must never directly contact human or animal skin. This is because the adhesive surface lacks ventilation holes, preventing heat dissipation. While no immediate harm may occur initially, prolonged heating causes heat to accumulate beneath the adhesive layer, potentially resulting in low-temperature burns. Please take particular care when elderly persons are using this appliance, as some elderly persons may have slower reactions. By the time they perceive the temperature as excessively hot, their skin may already have sustained damage.
