Super absorbent polymer (SAP)

Sodium polyacrylate; Cross-linked poly(acrylic acid) sodium salt; SAP; Super absorbent resin

CAS 9003-04-7

Chemical Formula (C₃H₄O₂)ₙ

Molecular Weight Varies (typically very high due to polymeric nature)

Super Absorbent Polymer (SAP) is a water-absorbing polymer capable of absorbing and retaining extremely large amounts of liquid relative to its own mass. Commonly used in hygiene products like diapers, agricultural applications, and spill control, SAP swells into a gel when it comes into contact with water or bodily fluids.

Industrial Uses

1.Paints, Coatings & Adhesives

  • Rheology Modifier: SAPs are used to control the viscosity and improve the consistency of water-based paints and coatings, ensuring smooth application and reduced sagging.
  • Moisture Retention: In adhesives, SAPs help retain moisture for prolonged bonding time and enhanced adhesion performance, especially in water-activated systems.

2. Flavours & Fragrances

  • Carrier Material: SAPs can act as carriers for slow-release delivery of fragrances in personal care and cleaning products.
  • Encapsulation Agent: SAPs encapsulate volatile compounds, ensuring a controlled and sustained fragrance release.

3. Energy 

  • Cable Wrapping: SAPs are used in power cables and fiber optic cables as a swelling agent to block water ingress, preserving cable integrity.
  • Battery Electrolyte Absorbents: SAPs can be used in gel electrolytes to stabilize and retain battery fluids in energy storage systems.

4. Lubricants & Automobiles

  • Anti-leakage Sealants: SAPs are used in automotive sealants and gaskets where absorption and expansion properties help seal micro-leaks.
  • Interior Hygiene Products: SAPs are found in disposable car mats and moisture control pads to maintain dryness and prevent odor.

5. Pharmaceuticals

  • Drug Delivery Systems: SAPs are explored in oral and topical drug delivery systems for controlled release and localized delivery.
  • Absorbent Pads: Used in medical-grade absorbent products like wound dressings and underpads for liquid retention and hygiene.
