Super Absorbent Polymer (SAP) is a material that can absorb and retain large amounts of liquid, making it ideal for use in hygiene products. SAP is used in a variety of hygiene products, including diapers, sanitary napkins, and adult incontinence products. SAP can absorb up to 100 times its own weight in water, which makes it an extremely effective material for these products. In addition, SAP is relatively inexpensive and easy to obtain, making it a popular choice for manufacturers.
