Sodium Polyacrylate(PAAS) CAS 9003-04-7
Sinochem is a trusted manufacturer and premier global supplier of Sodium Polyacrylate (PAAS, CAS 9003-04-7). PAAS is an exceptionally effective, water-soluble polymeric scale inhibitor and dispersant engineered for industrial water treatment, textile dyeing, papermaking, and ceramic processing.
It exhibits high thermal stability and operates efficiently under alkaline and high-concentration conditions. PAAS effectively disperses microcrystals or precipitates of calcium carbonate, calcium phosphate, and calcium sulfate, preventing scale accumulation on heat exchange surfaces.
- People use it for animals. Such as pet mats, absorb horse urine, and raise insects.
- People use it for health care. Such as paper pads (baby, children, and adults), feminine sanitary napkins, maternity care pads, medical bandages, wound dressings, etc.
- People use it in the industry, such as waste control, drilling fluid, corrosion inhibitor, concrete protection, etc.
Sodium Polyacrylate Description
Name: Sodium Polyacrylate (PAAS)
Molecular Formula: C3H3NaO2
CAS NO.: 9003-04-7
Density: 1.15 (30% aq.)
Boiling point: 141ºC
Melting point: 12.5ºC
Flashing point: N/A
Appearance: Colorless to light yellow transparent liquid
Solubility: Soluble, Insoluble in organic solvents such as ethanol and acetone.
Properties: Sodium polyacrylate is innoxious and soluble in water, it can be used in situations of alkaline and high concentration without scale sediment. PAAS can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. PAAS is used as scale inhibition and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.
Usage: Sodium polyacrylate can be used as scale inhibitor and dispersant in circulating cool water systems in power plants, iron & steel factories, chemical fertilizer plants, refineries and air conditioning systems. Dosage should be in accordance with water quality and equipment materials. When used alone, 2-15mg/L is preferred. When used as dispersant, the dosage should be determined by experiment.
Package: 200L plastic drum, IBC(1000L),customers’ requirement.
Storage: Sealed at room temperature, away from light, ventilated and dry place.
About Us: With over many years as a certified Sodium Polyacrylate & PAAS manufacturer, we combine innovation with stringent production standards to deliver high-performance product.

Acrylic acid sodium salt Applications
- Industrial Water Treatment: Functions as an effective scale inhibitor and dispersant in circulating cooling water systems, power plant boilers, steel mill cooling networks, and oilfield reinjection water. Typical dosage ranges from 2 to 15 mg/L based on water quality.
- Slurry & Pigment Dispersant: Serves as a high-performance dispersant for inorganic pigments, kaolin, carbon black, and ceramic slurries during papermaking, coatings manufacturing, and ceramic processing.
- Textile Processing Auxiliary: Used as a sizing agent, leveling agent, and dye dispersant in textile printing and dyeing to ensure uniform color distribution.
- Sugar Refining & Food Processing: Acts as a clarification agent and settling aid for sugar juice and process water systems.
