High CRC High AUL Super Absorbent Polymer（MODEL：SAP NR-511）
Superabsorbent Polymer(SAP) is a substance with a certain degree of cross-linking, 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.
Our Advantages
- Balanced performance for diverse hygiene applications
- High centrifugal water retention (CRC)
- Fast absorption rate
- Good absorption under pressure (AUL)
- Low residual monomer content
Scope Of Application
Suitable for both SAP sheet diapers and fluff pulp diapers
Often used as the top layer in composite cores
Popular composite core formulations: NR-511/NR-610S, NR-511/NR-760H
Blended with fluff pulp for manufacturing fluff pulp-based absorbent products
Baby diaper
Adult Diapers
Ice bag
