Polyacrylic Acid Sodium Salt (PAAS)

White, crystalline, soluble, anionic polymer.

Highly soluble, anionic polymer that efficiently manages metal ions in water systems. It is commonly employed as a scale inhibitor and dispersant, making it invaluable in industrial water treatment processes where prevention of scale and stabilization of suspended particles are critical. Its effectiveness at low concentrations makes it a cost-effective choice for maintaining water quality and equipment longevity.


PAAS is beneficial in agriculture primarily as a soil conditioner. It enhances soil structure by promoting the aggregation of soil particles, improving water retention, and reducing erosion. This improved soil condition allows for better root growth and nutrient uptake by plants. Moreover, PAAS helps in the efficient use of water resources, as it can increase the water-holding capacity of soils, particularly in arid regions, making it an important tool in water management and conservation strategies. It also minimizes nutrient leaching, ensuring that fertilizers are used more effectively, contributing to increased crop yields and sustainability in agricultural practices.

Pulp & Paper

In the pulp and paper industry, PAAS serves multiple functions. It acts as a dispersant in the papermaking process, helping to evenly distribute fillers and other additives within the paper pulp, resulting in improved paper quality and reduced clumping. This leads to smoother and more uniform paper surfaces, which are crucial for the final product quality. Additionally, PAAS is used to manage scaling in the extensive water recycling processes used in paper mills, protecting equipment from scale build-up and ensuring consistent process water quality, which is vital for efficient operations.

Water Treatment

In water treatment applications, PAAS is extensively used as a scale inhibitor and dispersant. It helps prevent the formation of calcium carbonate, calcium sulfate, and other mineral scales, which can clog pipes and reduce the efficiency of boilers and cooling towers. By binding with metal ions and dispersing solid particles, PAAS maintains the operational efficiency of water treatment systems and extends the lifespan of the infrastructure. Its role is critical in both municipal water systems, where it ensures that water remains safe and clean, and in industrial settings, where water quality directly impacts production processes.
