SAP(Super absorbent polymer) is a new type of functional polymer material SAP(Super absorbent polymer) is a new type of functional polymer material. It has a high water absorption function that absorbs hundreds to several thousand times water heavier than itself, and has excellent water preservation performance. Once the water absorption expands into a hydrogel, even the pressure is difficult to separate the water. Therefore, it has a wide range of uses in personal hygiene supplies, industrial and agricultural production, civil construction and other fields
