Introduction to The Application of Superabsorbent Polymer in the Field of Health

Super Absorbent Polymer (SAP) is a functional polymer material that is insoluble in water and organic solvents. The molecular chain contains a hydrophilic group such as a carboxyl group, an amino group, an amide group, a sulfonic acid group or a hydroxyl group, and is a strong hydrophilic polymer having a macromolecular crosslinked three-dimensional network structure. SAP has good water absorption and water retention properties, and can quickly absorb water hundreds to thousands of times more than itself. The network gel formed by it also has a certain strength, and it is not easy to extrude its water even under the application of mechanical pressure, and in a dry environment, the absorbed water can be slowly released.
Because of its good water absorption, moderate price and good safety performance, SAP is widely used in personal care products such as disposable diapers, adult incontinence products and feminine hygiene products.
