SCMET® PAA with excellent dispersion and antiscaling performance, is widely used in oilfield and refining industries. It prevents scaling/clogging in circulating/cooling water systems, adapts to high temperature/high salinity, and supports stable operations while cutting costs.
Polyacrylic acid (PAA) is a water-soluble, anionic synthetic polymer derived from the polymerization of acrylic acid monomers. It is typically available as a colorless to pale yellow liquid or solid powder, characterized by its high molecular weight variability and strong anionic charge. Non-toxic and environmentally compatible, PAA is widely recognized for its excellent chelating, dispersing, and scale-inhibiting properties, making it a versatile material in industrial water treatment and other fields.
Polyacrylic acid (PAA) offers several core advantages: it exhibits superior scale inhibition and dispersion capabilities, effectively preventing the formation and deposition of mineral scales such as calcium carbonate, calcium sulfate, and iron oxide. It has high calcium tolerance and stability under a wide pH range (typically 4–10), maintaining performance in both acidic and alkaline environments. Additionally, PAA boasts good chemical and thermal stability, resisting degradation at moderate temperatures, and demonstrates strong compatibility with other water treatment chemicals like organophosphonates, zinc salts, and corrosion inhibitors, enabling synergistic effects in compound formulations.
Polyacrylic acid (PAA) is primarily used as a scale inhibitor and dispersant in industrial water treatment systems, including oilfield circulating water, refinery cooling water, and power plant boiler water, where it prevents scaling and clogging in pipelines and equipment. Beyond the oil and gas industry, it finds 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 wastewater treatment (to disperse suspended solids and improve flocculation). It is also used in the food, cosmetics, and pharmaceutical industries for its thickening and stabilizing properties.
The price of Polyacrylic acid (PAA) is influenced by multiple factors: raw material costs (primarily acrylic acid monomers, whose prices fluctuate with petrochemical market trends), product specifications (including molecular weight, solid content, and purity grade—higher purity or customized molecular weight grades often command higher prices), order quantity (bulk purchases typically qualify for volume discounts), and supply chain dynamics (such as production capacity, transportation costs, and regional market demand). Additionally, packaging requirements (e.g., drum vs. bulk delivery) and quality certifications may also impact the final pricing. For accurate and up-to-date quotes, it is recommended to consult suppliers with specific order details.
