Ice-pad product descriptionName of the product: ice-pad Material: surface: environmental protection PVC composite special fabrics (waterproof treatment) filler: a specific high-tech nanometer ice-pad material Product Size: 15*25cm,20*35cm,25*35cm,30*35cm,30*40cm,40cm*45cmect. Product principle: adopting the latest high technology, the inner melt to liquid when the ice-pad absorb the heat diffused by human body, and keep the range of temperature at 6-7°C all the time, which makes the most comfortable temperature for the body. Crystallized automatically when the room temperature is below 27°C. Product feature: 1,This ice-pad can use directly when set the temperature at 30°C,without electricity, cooling effect is obvious within seconds. 2,The heat absorption capacity of this ice-pad is 35 times more than the water pad and gel pad based on the same weight. constant temperature lasts for 6-8 hours at 35°C.At 27°C,crystallized automatically within 1 hour. The lower the temperature, the faster it crystallized. 3,The filler use the environment protection material, no harm to the body, and can be used for more than 3 years. 4,The surface material use PVC under special treatment and won’t fracture under the pressurization of 200kg. Notes: 1, Prevent the ice-pad from sharp-edged tools and fireworks. In case of slight damage, use super glue to tape it. 2, In case of cold for the old,baby and valetudinarian, cotton cloth is needed to put on the ice-pad. 3, The cooling effect is relatively weak when the ice-pad is liquid. For better propose, alternate use. 4, The ice-pad crystallized automatically under 27°C.In hot areas, soak the product in cold water or lay in the fridge ,next to the air-conditioner or other cool places to make the product crystallize. The surface is waterproof, dry with the towel after contact water. 5,For drivers, avoid direct sunshine in case of leave when the external temperature is high. See note 4 if it cannot crystallize because of the high temperature. 6,When using as a laptop pad, the re-crystallized granules might be bigger because of the high temperature of laptop. It’s normal phenomenon and improved by using warm water to melt them and crystallization again. 7,Do not put in the washing machine; do not use hard brush to clean the surface. In case of dirty, use towel to wipe or detergent. 8,Put in the cool place and avoid direct sunlight. 9,The filler is inedible
