Sodium polyacrylate CAS#9003-04-7

Sodium polyacrylate CAS#9003-04-7

Basic Information

High Thickening EfficiencySodium polyacrylate forms a highly viscous transparent solution in water, with viscosity approximately 15–20 times higher than CMC or sodium alginate, making it an excellent thickening agent.


Excellent StabilityThe compound shows strong thermal stability and does not decompose even when heated to 300°C, while maintaining consistent viscosity during long-term storage.


Strong Water AffinityAs a high molecular compound containing both hydrophilic and hydrophobic groups, it demonstrates outstanding hygroscopic properties and dissolves gradually in water to form stable solutions.


Chemical Resistance and DurabilityIts viscosity is minimally affected by heating, neutral salts, and organic acids, and it performs particularly well under alkaline conditions, providing reliable performance in various formulations.

product description

Product Description of Sodium polyacrylate CAS#9003-04-7

Sodium polyacrylate is a white, odorless, tasteless powder with strong hygroscopicity. As a high-molecular polymer containing hydrophilic and hydrophobic groups, it dissolves in water to form a highly viscous transparent solution. The high viscosity of its 0.5% aqueous solution stems from ionic effects of numerous anionic groups, which stretch polymer chains and greatly raise apparent viscosity. Its viscosity is about 15–20 times that of CMC and sodium alginate..


Product Application of Sodium polyacrylate CAS#9003-04-7

Sodium polyacrylate acts as a scale inhibitor and detergent builder to enhance cleaning performance and regulate water hardness, also serving as a processing auxiliary in soaps and detergents.

It can absorb water-based spills, and works as a water retention and slow-release agent.

It is also widely applied as a suspending agent, stabilizer and emulsifier in various industrial formulations.
