Item Instructions:Take the 28°C Neck Cooling Tube as sample
* Usually the melting point of ice is 0°C, and the melting point of cooling ice tube is 28°C, it can maintain the skin surface temperature within a comfortable temperature range.
* Cooling neck tube has a high potential heat with phase change and a large heat absorption, which keep you staying cool longer.
* Portable and reusable
* No battery or charger needed, It freezes using any AC! Car AC, Office AC, Home AC, ice box, refrigerator, freezer
* In an environment below 28°C, whether it is indoors or outdoors, it can maintain the solid state of ice
* No risks of skin necrosis or frostbite through cooling by maintaining an optimal cooling temperature
* Main Material: Outer TPU/Inner PCM (Phase Change Material)
* The surface uses TPU, which has good biocompatibility, softness and comfort, and keeping good skin affinity in long time.
* The inner material is made of PCM(phase change material), this PCM new material freezes faster and lasts longer than water, which can cools neck quickly and absorbs a large amount of heat and keeping skin temperature comfortable for a long time.
How Does Neck Cooling Tube Works?
* When neck cooling tube is solid: it can be worn and used immediately.
* When cooling neck tube is liquid: put it in freezer and use it after pre-cooling for about 15-20 minutes.
How Long does Ice Tubes Keeping Cold?
When the average body temperature is 36.5℃, the continuous cold keeping time is about 90 to 120 minutes.(Test results under laboratory conditions. The duration may vary slightly depending on the use environment.)
