High Light Scale Inhibitor Sodium PolyacrylateDispersant PAASSuper-absorbent Polymer Poly(acrylic acid) sodium salt
Sodium Polyacrylate (PAA) CAS 9003-04-7
Scale inhibitor, dispersant, and super-absorbent polymer for water treatment and various industrial applications
Chemical Structure and Properties
Sodium polyacrylate is produced by the neutralization of polyacrylic acid with sodium hydroxide. The polymer backbone consists of repeating units of acrylic acid with carboxylate groups (-COONa) that give the molecule its characteristic anionic charge.
Property Details
CAS No. 9003-04-7
Chemical Formula [-CH₂CH(CO₂Na)-]n
Synonyms PAAS, Poly(acrylic acid) sodium salt, Poly(sodium acrylate)
Appearance Colorless to light yellow transparent liquid (solution form) or white powder
Solubility Freely soluble in water
pH (1% solution) 6.0-8.0 (neutralized salt form)
Molecular Weight Available in a range from ~2,000 to ~120,000 Daltons

PAA vs. PAAS: Understanding the Difference
A common point of confusion is the distinction between Polyacrylic Acid (PAA) and Sodium Polyacrylate (PAAS).
Parameter PAA (Acid Form) PAAS (Salt Form)
CAS No. 9003-01-4 9003-04-7
pH (1% solution) 2.0-4.5 (acidic) 6.0-8.0 (neutral to slightly alkaline)
Form Typically supplied as acidic liquid Supplied as liquid or powder
Application Used when acidic conditions are desired or for blending into formulations Preferred for alkaline systems and easier handling

Mechanism of Action
Lattice Distortion
When added to water systems, PAAS adsorbs onto the surface of microcrystals (such as calcium carbonate, calcium phosphate, and calcium sulfate). This adsorption distorts the normal crystal growth pattern, preventing the formation of hard, adherent scale deposits on heat exchangers and pipelines.
Electrostatic Repulsion / Dispersion
As an anionic polyelectrolyte, PAAS increases the negative charge on particle surfaces. The resulting electrostatic repulsion keeps particles suspended in the water, preventing them from agglomerating and settling. This allows suspended solids and microcrystals to be easily removed through blowdown or filtration.

Performance Advantages
Advantage Description
Broad-Scale Control Effectively inhibits calcium carbonate, calcium phosphate, and calcium sulfate scales
Alkaline Compatibility Performs well in high-pH and high-concentration environments without scale formation
Non-Toxic Innocuous and environmentally safe; does not pollute the environment upon discharge
Synergistic Effects Works effectively in combination with organic phosphonates, phosphates, and other treatment chemicals
High Calcium Tolerance Maintains performance even in high-hardness water conditions
Super-Absorbent Property Can absorb 100-1,000 times its mass in water (in cross-linked form)

Applications
Industrial Water Treatment
PAAS is widely used as a scale inhibitor and dispersant in circulating cooling water systems, including:
  • Power plants
  • Steel mills and chemical fertilizer plants
  • Oil refineries and petrochemical plants
  • HVAC and air conditioning systems
Super-Absorbent Polymer (SAP)
In its cross-linked or solid form, sodium polyacrylate acts as a "water lock" and is used in:
  • Baby diapers and adult incontinence products
  • Feminine sanitary napkins
  • Medical bandages and wound dressings
  • Flood control "sandless" sandbags
  • Agricultural soil water retention
Manufacturing and Industrial Processes
  • Detergents: Improves soil dispersion and anti-redeposition performance
  • Textiles and Dyeing: Acts as a dispersant for pigments and fillers
  • Papermaking: Prevents scale formation and disperses fillers
  • Ceramics and Coatings: Functions as a dispersant and rheology modifier
Other Applications
  • Synthetize: Viscosity modifier for gels and ointments
  • Cosmetics: Thickener and stabilizer for water-based emulsions
  • Oilfield: Fluid loss additive in drilling fluids

Technical Specifications
Liquid Grade (Typical)
Parameter Standard Grade High-Concentration Grade
