SINOFLOC superabsorbent polymers (known as SAP) are water insoluble polymer, cross-linked copolymer of acrylic acid. It can absorb water which is hundreds to thousands of times heavier than its own, and it has excellent water retention. Once the absorbed water is expanded into a hydrogel, it is difficult to separate the water even when it is pressed. Therefore, it is widely used in personal hygiene products, industrial and agricultural production, civil construction and other fields. Because of the strong water absorption capacity and excellent water retention property, the Water Insoluble Polymer absorbent is widely used in agriculture and forestry fields as the soil water retention agent. China is lack of water resources. Therefore, the application of water retaining agent becomes more and more important. Currently in domestic, Water Insoluble Polymer (SAP) products have been used for many kinds of plants in the fields such as grain, cotton, oil, sugar, tobacco, fruit, vegetables, f...
