The phase change material filled with the cooling collar is n-alkane, which absorbs a large amount of heat when it is transformed from a solid to a liquid, thereby cooling the human body. The phase change temperature of the material is about 26°C, so when the cooling ice ring comes into contact with the human body, it absorbs heat and converts it into a liquid form, giving the wearer a cooling sensation.
When wearing a cooling ice ring, pay attention to the following:
Try to avoid wearing a cooling ice ring for a long time: In hot weather, people are prone to sweating in the neck, and wearing a cooling ice ring for a long time, which rubs against the neck skin repeatedly, may irritate the local skin and induce skin diseases such as eczema and folliculitis. In addition, people who are allergic to thermoplastic polyurethane elastomer materials are prone to irritant contact dermatitis caused by wearing cooling ice rings.
Attention should be paid to the discomfort of the skin in contact with the cooling ice circle: people with a history of cold urticaria, Raynaud's disease, etc., should wear it with caution.
Keep away from fire sources and high-temperature places: The filling n-alkane of the cooling ice circle is flammable, and the use environment does not exceed 50°C, so it should not be placed in a place where young children and pets can reach it.
To sum up, although the cooling ice circle has a certain cooling effect, it is still necessary to pay attention to the use method, scientific heatstroke prevention, and avoid being cold.
