Sodium Polyacrylate, identified by its CAS No. 9003-04-7 and chemical formula (C3H3NaO2)n, is a highly effective chemical auxiliary widely recognized for its pivotal role in various industrial applications, particularly in the paper manufacturing sector. As a versatile anionic polyelectrolyte, this polymer stands out as an indispensable paper making additive and dispersant, offering superior performance in optimizing the quality and efficiency of pulp and paper production processes.

Characterized as a colorless or light yellow viscous transparent liquid, Sodium Polyacrylate boasts impressive specifications, including a typical solid content of 40% (customizable to specific requirements), a viscosity ranging from 100-300 mPa•s at 25ºC, and a pH value between 7.0 and 9.0. Its excellent solubility in water ensures ease of integration into aqueous systems, making it a highly practical choice for demanding industrial environments. The typical transport package includes 160L or 1000L barrels, with a substantial production capacity of 20000 tons per year to meet global demand.

The core strength of Sodium Polyacrylate lies in its exceptional dispersing capabilities. It exhibits a profoundly obvious dispersing effect on a wide range of pigments and fillers commonly used in paper production, such as calcium carbonate, calcium hydroxide, talcum powder, titanium dioxide, kaolin, and clay. This strong dispersibility is crucial for creating uniform slurries, preventing agglomeration, and ensuring a smooth, consistent coating application on paper. Beyond its dispersing prowess, the product is praised for its good heat resistance, excellent miscibility, and efficient performance, all contributing to stable slurry viscosity with minimal foam generation. It is also distinguished as a non-toxic, non-corrosive, and odorless compound, classifying it as a non-dangerous product safe for handling and use in industrial settings.

Specifically tailored for paper processing, Sodium Polyacrylate proves highly suitable for the wet grinding of heavy calcium carbonate pigment systems across all levels. Its application significantly contributes to reduced energy consumption during grinding, yields materials with remarkably low viscosity post-grinding, and maintains excellent stability of slurry viscosity across varying temperatures and pH values. These attributes are critical for achieving high-quality paper coatings and improving the overall mechanical properties of the finished product. The polymer enhances the paper's surface characteristics, leading to better printability, improved gloss, and increased opacity.

Beyond its primary function in paper and pulp, Sodium Polyacrylate's unique super-absorbent polymer (SAP) properties grant it a broad spectrum of applications across diverse industries. Its ability to absorb hundreds of times its own mass in water makes it a preferred component in hygienic products like diapers and sanitary napkins, where efficient liquid retention is paramount. In agriculture, it serves as an effective water-retaining agent, improving soil moisture availability and water infiltration capacity, thereby supporting plant growth and water conservation efforts. It is also utilized as a thickening agent in various consumer products, including hair gels and soaps, and as a chelating agent in detergents to neutralize heavy metals, enhancing cleaning efficiency.

Furthermore, this versatile polymer finds utility in specialized industrial applications such as the petroleum industry, where it acts as a drilling fluid, and in metalworking as a quenching agent. Its environmental benefits extend to low-salt animal skin preservation and, significantly, to the removal and recovery of harmful metal ions from aquatic environments, offering a cost-effective and environmentally sustainable solution for water purification. The biocompatible nature of Sodium Polyacrylate also opens avenues in drug delivery systems, particularly in microencapsulation for probiotics, where its acid buffering and binding capacities enhance the viability of active substances.

Safety considerations for Sodium Polyacrylate are important. While the polymer itself is non-irritating to the skin due to its large molecular size, trace amounts of residual acrylic acid from the manufacturing process should be kept below 300 PPM, as higher levels could cause skin irritation. In powdered form, it should not be inhaled, and large spills mixed with water can create slippery surfaces or clog drainage systems. However, overall, Sodium Polyacrylate is considered non-toxic and presents no major risks under normal handling conditions, making it a reliable choice for a wide array of industrial and consumer applications.

When considering the acquisition of such a crucial industrial chemical, potential buyers often seek clear information regarding product quality, pricing, and availability. For those looking to purchase high-quality Sodium Polyacrylate, understanding the typical price range, often quoted between US$800.00 and US$1,000.00 per ton, and the minimum order quantity (MOQ) of 1 ton is essential for effective procurement planning. Establishing a relationship with a reputable manufacturer or supplier is paramount to ensure consistent product purity and reliable supply chain logistics.
