Explore our flagship portfolio of Anionic, Cationic, and Nonionic Polyacrylamide formulations engineered for extreme industrial demands.
Polyacrylamide (PAM), designated under CAS registry numbers (such as CAS 9003-05-8 for cationic and homopolymer derivatives), is a synthetic linear resin synthesized through the free-radical polymerization of acrylamide monomers. As an indispensable high-molecular-weight water-soluble polymer, its functional mechanics rely on extended macromolecular chains that adsorb onto suspended colloidal solids, forming bridging networks that aggregate micro-flocs into rapidly settling macro-flocs.
Depending on ionic functionalization, molecular weight distribution (ranging from 3 Million to over 25 Million Daltons), and physical morphology (dry powder, emulsion, micro-bead), PAM operates across four main ionic configurations: Anionic (APAM), Cationic (CPAM), Nonionic (NPAM), and Amphoteric (MPAM). Each chemistry addresses specific zeta potential thresholds, solution pH parameters, and solids characteristics in industrial liquid-solid separation processes.
Standardized chemical grade classifications utilized across global water management and industrial processing infrastructure.
Synthesized via copolymerization of acrylamide and DAC/DMC monomers. Crucial for negatively charged organic sludge dewatering in municipal and biological WWTPs.
Carboxyl-functionalized polymers featuring high-to-ultra-high molecular weights. Ideal for inorganic suspended solids, mineral tailing clarification, and EOR.
Pure acrylamide homopolymers offering neutral charge performance. Exceptionally stable under strong acidic wastewater conditions and mineral leaching baths.
Tailored charge densities (10% - 80% mole ratio) designed for high-shear centrifuge and belt filter press dewatering operations.
Extreme chain length polymers delivering high tensile floc resilience for drag reduction and Enhanced Oil Recovery (EOR) sweep efficiency.
Engineered to maintain chain elasticity in low pH (<3.0) processing streams, including acidic metal extraction and pickling liquors.

Selecting the optimal polyacrylamide grade requires aligning chemical characteristics with stream parameters such as suspension pH, ionic strength, particle charge density, solids content, and mechanical dewatering equipment type. The technical table below outlines standard operational parameters:
| Polymer Type | Ionicity Range (%) | Molecular Weight (M Daltons) | Optimal pH Range | Primary Industrial Application |
|---|---|---|---|---|
| Anionic PAM (APAM) | 5% – 60% | 8.0 – 25.0 | 6.0 – 14.0 | Mining Tailings, Sand Washing, Municipal Sewage, Paper Retention |
| Cationic PAM (CPAM) | 5% – 80% | 6.0 – 15.0 | 1.0 – 8.0 | Municipal Sludge Dewatering, Textile Dyeing, Food Processing WWTP |
| Nonionic PAM (NPAM) | 0% – 5% | 3.0 – 12.0 | 1.0 – 8.0 | Acidic Industrial Effluent, Soil Stabilization, Mineral Extraction |
| Amphoteric PAM (MPAM) | Variable (+/-) | 4.0 – 10.0 | 2.0 – 12.0 | Complex Oily Wastewater, Refined Paper Sludge, High Salinity Water |
Note: Customized molecular weight and ionicity tailoring are available upon technical request following comprehensive laboratory jar testing.
Strategic purchasing guidelines for procurement executives, EPC contract managers, and municipal utility directors.
Evaluating commercial flocculants purely on cost per metric ton often leads to inflated operational budgets. Higher-grade polymers with optimized molecular chain lengths achieve target clarity and cake dryness at up to 30% lower dosing rates (ppm), dramatically lowering overall chemical consumption costs.
Before purchasing bulk orders, enterprise buyers should conduct standard jar tests to evaluate floc settling speed, supernatant turbidity (NTU), cake moisture percentage, and shear resistance under dynamic agitation (such as high-speed centrifuge feed conditions).
Polyacrylamide powder is highly hygroscopic. Oubo enforces multi-layer moisture-proof packaging options—including palletized 25kg Kraft paper bags with PE inner liners and 750kg jumbo sacks—guaranteeing 24-month stability during long sea voyages and tropical warehouse storage.
