Understanding the synthesis chemistry, hydrolysis metrics, and mechanical parameters of industrial-grade APAM flocculants.
The performance of APAM in flocculation depends on two primary molecular mechanisms: charge neutralization and bridging flocs. The charge density (hydrolysis degree, typically ranging from 10% to 60%) dictates how effectively the polymer chain interacts with the electrostatic double layers of suspended particles. The molecular weight (ranging from 5 Million to upwards of 25 Million Daltons) determines the physical length of the polymer chain.
High-molecular-weight APAM chains stretch out in aqueous solutions due to the electrostatic repulsion between the negative carboxylate groups along the carbon backbone. When this chain touches the boundary layer of inorganic particles, it forms multiple physical adsorption sites. This creates giant macro-flocs through "bridging" which rapidly precipitate under gravity, increasing dewatering rates and filtrate clarity.
| APAM Parameter Grade | Molecular Weight (Million Da) | Degree of Hydrolysis (%) | Solid Content (%) | Dissolving Time (mins) |
|---|---|---|---|---|
| Ultra High Molecular Weight (UHMW) | 20.0 – 25.0 | 20 – 30 | ≥ 88% | ≤ 60 |
| High Molecular Weight (HMW) | 15.0 – 20.0 | 15 – 25 | ≥ 88% | ≤ 50 |
| Medium Molecular Weight (MMW) | 10.0 – 15.0 | 10 – 20 | ≥ 88% | ≤ 45 |
| Low Molecular Weight (LMW) | 5.0 – 10.0 | 30 – 50 | ≥ 88% | ≤ 40 |
At Wuxi BS Water Treatment Chemicals Co., Ltd., we use a computerized batch solution polymerization setup. High-purity acrylamide monomer is mixed with acrylic acid in deionized water. The copolymerization reaction is initiated using a redox catalyst system combined with azo compounds at controlled temperature ramps.
This method minimizes free monomer residues (ensuring acrylamide monomer remains strictly below 0.05%), which is critical for drinking water applications. The resulting polymer gel is cut, dried in fluid-bed dryers, and milled to customized granule size ranges to prevent dust and caking during transport.
Traditional APAM chains can shrink in high-salinity solutions because divalent ions (like Ca2+ and Mg2+) screen the negative charges on the polymer. Our R&D team is working on incorporating monomer additions like AMPS (2-Acrylamido-2-methylpropane sulfonic acid) into the polymer structure. This modification keeps the polymer chains extended even in harsh, high-temperature and high-salt reservoirs, opening up new opportunities for enhanced oil recovery (EOR) and deep-shaft mining operations.
How our tailored Anionic Polyacrylamide grades optimize processes in different industrial sectors.
We supply high-viscosity APAM to municipal and industrial clarifiers. By accelerating sedimentation rates, it helps water treatment plants increase processing capacities without major upgrades to physical infrastructure. It is also widely used as an auxiliary flocculant with Polyaluminium Chloride (PAC) to treat high-turbidity river waters.
In modern mineral processing (coal washing, alumina processing, gold/copper extraction), rapid tailing separation is essential. Our high-molecular-weight APAM helps thickeners process copper concentrates and fine coal tailings quickly, recycling process water and ensuring compliance with dry stack tailing regulations.
In the oil and gas sector, APAM is used to modify rheological properties in polymer flooding and drag reduction. Our polymer grades help control fluid loss, stabilize drilling muds in shale formations, and improve sweep efficiency during secondary and tertiary recovery phases.
APAM acts as a retention and drainage aid on high-speed paper machines. By flocculating fibers and fillers, it improves sheet formation, boosts dry strength properties, and helps close loop white water systems to minimize fiber loss.

Dry polyacrylamide is highly hygroscopic. If it absorbs moisture, it can cake and degrade. We package our products in multi-wall kraft paper bags with internal PE liners, or 750kg and 1000kg bulk super sacks. All bulk shipments are palletized and stretch-wrapped to prevent humidity ingress during sea transit.
Our products meet major international certifications, including ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health and Safety). We provide comprehensive Safety Data Sheets (SDS) and technical data sheets with every batch, ensuring compliance with REACH and other national import rules.
