Sodium polyacrylate SCMET® PAAS

What is Sodium polyacrylate (PAAS)?

Sodium polyacrylate (PAAS) is a water-soluble, anionic synthetic polymer derived from the polymerization of acrylic acid monomers followed by neutralization. It is typically supplied as a colorless to pale yellow viscous liquid or white powder, characterized by its high molecular weight, strong anionic charge, and excellent water-absorbing capacity. Non-toxic and environmentally friendly, PAAS is widely recognized for its superior dispersion and chelating properties, making it a versatile material in industrial, agricultural, and daily chemical applications.

What are the key features of Sodium polyacrylate (PAAS)?

PAAS exhibits exceptional scale inhibition and dispersion capabilities, effectively preventing the formation and deposition of mineral scales such as calcium carbonate, calcium sulfate, and magnesium carbonate. It maintains stable performance under alkaline conditions (pH 7–11) and medium cycles of concentration, with high calcium and magnesium tolerance. The polymer also boasts good chemical stability, resisting degradation in harsh industrial environments, and demonstrates strong compatibility with other water treatment chemicals like organophosphonates and corrosion inhibitors, enabling synergistic effects in compound formulations. Additionally, it has excellent solubility in water and low dosage requirements for optimal performance.

What are the main applications of Sodium polyacrylate (PAAS)?

PAAS is primarily used as a scale inhibitor and dispersant in industrial water treatment systems, including oilfield circulating water, refinery cooling water, and industrial boiler water, effectively preventing scaling and clogging in pipelines and equipment. Beyond water treatment, it finds extensive applications in papermaking (as a retention and drainage aid), textile printing and dyeing (for dye dispersion and anti-staining), detergent formulations (as a builder to enhance cleaning efficiency), and agriculture (as a water-retention agent for soil). It is also used in ceramics, coatings, and construction materials industries for its dispersion and stabilization properties, as well as in food and cosmetics as a thickening or stabilizing agent.

What factors affect the price of Sodium polyacrylate (PAAS)?

The price of Sodium polyacrylate (PAAS) is influenced by several key factors, including raw material costs (primarily acrylic acid, whose prices fluctuate with petrochemical market trends), product specifications (such as molecular weight, solid content, and purity grade—higher purity or customized grades often command higher prices), and order quantity (bulk purchases typically qualify for volume discounts). Supply chain dynamics, such as transportation costs, regional market demand, and production capacity, also play a significant role. Additionally, packaging requirements (e.g., drum vs. bulk delivery) and quality certifications may impact pricing, while seasonal changes in raw material supply can lead to short-term price fluctuations. For accurate and up-to-date quotes, it is recommended to consult suppliers with specific order details and application scenarios.
