"MIRACLE" SAP has special structure and excellent hydrophilic group, which make it not dissolve in water but can absorb hundred times of water or several decuples of bio-brine (body fluid) , and process superior water retaining capacity, and the water absorbed is hard to extrude. Several excellent capacities of "Miracle" SAP ensure the high quality of sanitary products, such as the high absorbing speed, good absorbance under load, good gelatin intensity, and excellent capacity of anti-moisture. "Miracle" SAP adopts advanced manufacturing techniques, thus monomer residual is low, and it's non-poisonous and smell-less, and no stimulation to skin. Under certain conditions it can degrade into small molecule such as water, carbon dioxide, ammonia etc. , thus it is a green and environment protecting high-tech product.
