Anionic Polyacrylamide (APAM), designated under CAS Registry Number 9003-05-8, represents a class of water-soluble linear high-molecular-weight polymers synthesized via copolymerization of acrylamide monomers with negative charge functional groups (primarily acrylic acid or sodium acrylate). Functioning as a high-efficiency synthetic organic flocculant, APAM plays an indispensable role in solid-liquid separation, water clarification, sludge dewatering, and enhanced resource recovery across global heavy industries.
The molecular dynamics of Anionic Polymer Flocculants depend on two core parameters: Molecular Weight (MW), ranging from 5 Million to upwards of 25 Million Daltons, and Anionic Charge Density (Degree of Hydrolysis), spanning from 10% to 60%. When introduced into aqueous suspensions containing positively charged colloidal particles or inorganic mineral slurries, APAM operates via dual mechanism: charge neutralization and macromolecular bridging. The extended polymer chains adsorb onto particle surfaces, binding suspended fines into large, fast-settling macroscopic flocs, drastically accelerating sedimentation and filtration rates.
From 6 Million to 25 Million Daltons. Optimized for high-shear environments, thickener underflow clarification, and rapid flocs formation in mining and municipal applications.
Precise control of hydrolysis degree (10% to 60%). Custom charge density matching ensures optimal zeta-potential neutralization across varying effluent pH levels.
Manufactured using advanced bio-enzymatic processes maintaining acrylamide residual monomer levels below 0.05% (500 ppm), satisfying stringent potable and environmental standards.
As a leading China Anionic Polymer Flocculant Manufacturer, Qingdao Oubo Chemical Co., Ltd. provides rigorously validated Material Safety Data Sheets (MSDS) compliant with Globally Harmonized System (GHS), EU REACH, ISO 11014-1, and US OSHA Hazard Communication Standards. Understanding the chemical handling profile of APAM is paramount for plant engineers, safety officers, and procurement managers.

Qingdao Oubo Chemical Co., Ltd. utilizes patented bio-catalytic biological processes to synthesize acrylamide monomer. Unlike traditional chemical catalytic methods, biological synthesis operates under mild reaction conditions, yielding higher purity monomers without copper ions or hazardous contaminants. This guarantees superior polymer chain linearity, elevated molecular weights, and ultra-stable performance during industrial dewatering and clarification.
Situated inside the Free Trade Zone of Qingdao, China, Oubo Chemical benefits from direct access to one of the world's premier deep-water shipping terminals. Raw materials are sourced directly from global petrochemical leaders such as SINOPEC and Eni. Fully automated production lines coupled with integrated port logistics ensure fast lead times, duty-free storage flexibility, and resilient container availability for international clients.
Applied in industrial solid-liquid separation, sedimentation, and clarification. APAM accelerates coagulation in raw water clarification and works synergistically with coagulants in municipal sewage and tannery effluent plants.
Essential for coal washing tailings recovery, gold, silver, iron, copper, and aluminum ore slurry settling. Provides fast clarification in thickeners and improves cake dry solids during belt filter pressing.
Functions as a mobility control agent in Enhanced Oil Recovery (EOR), friction reducer in hydraulic fracturing, profile control agent, and fluid loss reducer in water-based drilling mud systems.
Serves as dry/wet strength agents, retention aids, and filter aids. Enhances fine fiber retention, speeds wet-end machine dewatering, reduces furnish costs, and clarifies white water loops.
Food-grade compliant APAM formulations used for juice clarification, sugar cane liquor flotation, and starch processing effluent settling, optimizing sugar yields and mud filtration speed.
Functions as a durable textile sizing agent and fabric finishing additive. Highly effective in coagulating residual dyes and organic suspended solids in textile dyeing wastewater operations.
