Polyacrylamide (PAM) is a high molecular weight, water-soluble polymer that has found extensive use across a wide spectrum of industries due to its unique chemical and physical properties. Formed from acrylamide monomers, PAM acts as an effective flocculant, thickener, friction reducer, and soil conditioner. As a leading manufacturer and supplier of industrial chemicals in China, we offer a comprehensive range of PAM products designed to meet the diverse needs of global industries.

The versatility of PAM stems from its polymer chain structure, which can be modified to exhibit different ionic charges. This leads to the three primary types of PAM: anionic, cationic, and nonionic. Each type possesses distinct characteristics that make it suitable for specific applications. Understanding these differences is key to selecting the optimal PAM for any given process.

Anionic Polyacrylamide (APAM): APAM carries a net negative charge. It is particularly effective in neutralizing positively charged suspended particles, such as clays, metal ions, and organic colloids. APAM is widely used in wastewater treatment, especially for neutral to alkaline conditions, and in applications like coal washing, mineral processing, and red mud settling. Its ability to bridge positively charged particles makes it an excellent flocculant for improving solid-liquid separation.

Cationic Polyacrylamide (CPAM): CPAM carries a net positive charge. It is highly effective at binding with negatively charged particles, including organic matter, bacteria, and dyes. This makes CPAM invaluable in municipal sewage treatment, sludge dewatering, and in industries like textiles, paper manufacturing, and oilfield operations where negatively charged contaminants are prevalent. Its strong electrostatic attraction leads to rapid floc formation and efficient separation.

Nonionic Polyacrylamide (NPAM): NPAM has no net electrical charge. It primarily functions through bridging flocculation, where its long polymer chains physically link suspended particles. NPAM is useful in applications where the water has low ionic content or when avoiding charge interactions is beneficial. It can be used in various industrial wastewater treatments and some paper applications.

Beyond these primary types, amphoteric PAM, which contains both anionic and cationic charges on the same molecule, offers enhanced performance in complex water conditions and can simplify treatment processes by avoiding precipitation issues that can arise from mixing anionic and cationic PAM. We also offer specialized rheological flocculants for specific industrial needs.

The applications of PAM extend far beyond water treatment. In the oil and gas sector, high molecular weight PAM is crucial for enhanced oil recovery (EOR) as a viscosity enhancer and for hydraulic fracturing as a friction reducer. In the paper industry, it acts as a retention aid, drainage aid, and dry strength agent, improving product quality and production efficiency. Other significant applications include mining, sugar refining, construction, and agriculture, where it aids in soil stabilization and erosion control.
