Sodium polyacrylate CAS#9003-04-7

High Thickening EfficiencySodium polyacrylate forms a highly viscous transparent solution in water, with viscosity approximately 15–20 times higher than CMC or sodium alginate, making it an excellent thickening agent.


Excellent StabilityThe compound shows strong thermal stability and does not decompose even when heated to 300°C, while maintaining consistent viscosity during long-term storage.


Strong Water AffinityAs a high molecular compound containing both hydrophilic and hydrophobic groups, it demonstrates outstanding hygroscopic properties and dissolves gradually in water to form stable solutions.


Chemical Resistance and DurabilityIts viscosity is minimally affected by heating, neutral salts, and organic acids, and it performs particularly well under alkaline conditions, providing reliable performance in various formulations.

Product Description

Product Description of Sodium polyacrylate CAS#9003-04-7

Sodium polyacrylate is a white, odorless, tasteless powder with strong hygroscopicity. As a high-molecular polymer containing hydrophilic and hydrophobic groups, it dissolves in water to form a highly viscous transparent solution. The high viscosity of its 0.5% aqueous solution stems from ionic effects of numerous anionic groups, which stretch polymer chains and greatly raise apparent viscosity. Its viscosity is about 15–20 times that of CMC and sodium alginate..


Product Application of Sodium polyacrylate CAS#9003-04-7

Sodium polyacrylate acts as a scale inhibitor and detergent builder to enhance cleaning performance and regulate water hardness, also serving as a processing auxiliary in soaps and detergents.

It can absorb water-based spills, and works as a water retention and slow-release agent.

It is also widely applied as a suspending agent, stabilizer and emulsifier in various industrial formulations.

FAQ

Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.


Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.


Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.


Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
