The Zhengda cooling pad is used by new generation high polymer material and the spatial crossing linking technology, has high absorbing water, high water resistant, anti-to get moldy and spoil, the service life long and so on merits. Moreover the evaporation relative surface is big, the temperature decrease efficiency reaches above 80%, does not contain the surface active agent, nature absorbing water, the propagation rate is quick, the potency is lasting. A water drop 4~5 second then proliferated finishes. International same profession standard nature absorbing water is 60~70mm/5min or 200mm/1.5hour.The Zhengda cooling pad do not include causing the skin sensibility chemical substances and so on phenol, installs when the use to human body non-toxic harmless, green, security, energy conservation, environmental protection, economy.
