Polyacrylamide (PAM) is a synthetic resin prepared by polymerizing acrylamide. It is a white, solid, water-soluble polymer of acrylamide, mostly used as a flocculant, coagulant, and filtration aid across diverse industrial domains.
Synthesized via copolymerization of acrylamide and acrylic acid monomers. APAM carries negative ionic charges along its polymer backbone. It exhibits high intrinsic viscosity and exceptional chain expansion in neutral to alkaline pH environments.
Primary Mechanism: Charge neutralization and bridging adsorption on positively charged inorganic suspended solids such as clay, silica, and metallic oxides.
MW Range: 6 Million to 25 Million Daltons.
Formulated by copolymerizing acrylamide with cationic monomers such as DAC (Acryloyloxyethyltrimethyl ammonium chloride) or DMC (Methacryloyloxyethyltrimethyl ammonium chloride). CAS Registry: 9003-05-8.
Primary Mechanism: Neutralization of negatively charged organic colloids, facilitating dense sludge cake formation during mechanical dewatering.
Charge Density: 5% to 80% ionic substitution.
A homopolymer of pure acrylamide offering neutral surface charge characteristics. NPAM relies predominantly on hydrogen bonding mechanisms rather than electrostatic attraction to bind micro-particles.
Primary Mechanism: Flocculation under strongly acidic wastewater conditions where ionic charges are suppressed, or in complex multi-mineral pulp slurries.
MW Range: 3 Million to 15 Million Daltons.
| Polymer Type | Ionic Charge (%) | Molecular Weight (Million) | Optimal pH Range | Primary Industrial Sector |
|---|---|---|---|---|
| APAM (Anionic) | 5 - 60% | 8.0 - 25.0 | 7.0 - 14.0 | Coal Washing, Metallurgical Tailings, Paper Retention |
| CPAM (Cationic) | 5 - 80% | 4.0 - 12.0 | 1.0 - 8.0 | Municipal Sludge Dewatering, Textile Effluent, Biological Waste |
| NPAM (Nonionic) | 0 - 2% | 3.0 - 15.0 | 1.0 - 8.0 | Acidic Leach Mining, Soil Stabilization, Oil Drilling Mud |
| Mannich PAM | 20 - 50% (Amine) | 5.0 - 10.0 | 4.0 - 9.0 | High-solids Industrial Sewage, Tannery Effluent |

Oubo's tailored polymer chemistry provides comprehensive, high-efficiency solutions across major global industrial sectors.
As a flocculating agent, mainly used in industrial solid-liquid separation processes, including settlement, clarification, concentration, and sludge dewatering processes. Polyacrylamide plays an important role in municipal sewage treatment and industrial wastewater treatment. Increasingly stringent regulations promote the development of the water treatment industry.
For municipal sewage treatment industry, it is also widely used in leather, paper making, citric acid, vegetable protein extract, dyeing, pharmaceutical, incense, etc.
Applications for major sectors: Urban Sewage Treatment, Paper, Food Processing, Petrochemical, Metallurgical Processing, Dyeing, Sugar, and all kinds of industrial wastewater treatment.
In the paper industry, PAM can be used as dry strength agents, retention agents, and filter aids. They greatly improve paper quality, enhance physical strength, and reduce fiber loss. They are simultaneously utilized in white water treatment and deinking flocculation.
Polyacrylamide is widely used in oil exploration, profile control, plugging agents, drilling fluids, and fracturing fluid additives. It effectively reduces drilling fluid loss, enhances shale inhibition, provides cooling/lubrication to drill bits, and assists carrying cuttings and well cementing.
Key Application Domains:
Polyacrylamide is widely applied across mineral processing plants. It separates valuable minerals from gangue slime, acts as a high-speed thickener flocculant, and seals mining conduits. Our comprehensive portfolio includes nonionic, anionic, and cationic polymers at tailored molecular weights for:
Polyacrylamide is utilized in sugarcane and sugar beet juice clarification, mud settling, and syrup flotation. Food-grade ultra-low residual monomer PAM products ensure fast flocs formation and clear juice overflow, lowering color bodies and maximizing sugar recovery yields.
In textile processing, PAM acts as a sizing agent, finishing auxiliary, and fabric treating agent. In wastewater, cationic and anionic PAM efficiently break dye emulsions, remove COD/BOD, and decolorize complex aromatic dye streams.
To protect moisture-sensitive polyacrylamide powders during transoceanic shipping, Oubo supplies standardized multi-layer moisture barrier packaging options.
Unbranded 25kg craft paper bags with PE inner liner, ideal for private label distributors.
