This paper presents an investigation on the thermal characteristics in a layer of an exothermic powder mixture that is utilized in body warmers, hot compresses and so on. The research objective is to develop a manufacturing process that enables the exothermic temperature to be controlled in order to prevent cases of low-temperature bums. Absorbent polymer powder including saline solution is added into the exothermic powder mixture, and its effects on the reaction velocity and the thermal characteristics are examined experimentally.
