Ultra High CRC Super Absorbent Polymer（MODEL：SAP NR-611）
Superabsorbent polymer (SAP) is a cross-linked polymer synthesized through the polymerization and neutralization of raw materials such as acrylic acid, sodium hydroxide, and cross-linking agents. It can rapidly absorb hundreds of times its own weight in water, forming a hydrogel that retains water even under pressure without releasing it. The product is typically supplied in granular or powdered form and features fast water absorption, high absorbency, excellent hydrolysis resistance, and low residual monomer content. Primarily used in disposable hygiene products such as baby diapers and adult diapers.
