Polyacrylamide (CAS 9003-05-8) is a synthetic water-soluble polymer composed of acrylamide subunits. It functions as a flocculant, rheology modifier, friction reducer, binder, and retention aid across multiple global industries.
Copolymerized with acrylamide and acrylate monomers. APAM carries a negative charge density ranging from 5% to 80% and ultra-high molecular weights up to 25 Million Daltons. Ideal for inorganic suspended solids, mineral dressing, and enhanced oil recovery (EOR).
Synthesized via copolymerization with cationic monomers (DAC/ADAME). CPAM carries positive charges (10% - 80% charge density) optimized for organic matter flocculation, municipal sludge dewatering, textile dyeing wastewater, and paper machine retention.
Homopolymerized acrylamide with neutral ionic properties. Demonstrates superior performance under highly acidic or saline industrial effluent conditions, oilfield drilling fluid thickening, and specialized soil stabilization.

|---|---|---|---|---|---|
| Anionic PAM (APAM) | 5% – 80% (Negative) | 6 – 25 Million | ≥ 88% Dry Powder | ≤ 60 Minutes | Mining, EOR, River Water Clarification |
| Cationic PAM (CPAM) | 10% – 80% (Positive) | 8 – 15 Million | ≥ 88% Dry Powder | ≤ 45 Minutes | Municipal Sludge Dewatering, Textile Effluent |
| Nonionic PAM (NPAM) | < 3% Neutral | 5 – 12 Million | ≥ 88% Dry Powder | ≤ 60 Minutes | Acidic Wastewater, Coal Washing, Soil Agent |

Our O'brien brand Polyacrylamide solutions deliver optimal bridging, charge neutralization, and thickener performance across global vital industries.
As an advanced flocculating agent, Oubo Polyacrylamide is primary utilized in solid-liquid separation processes, including sedimentation, clarification, filtration, and sludge dewatering. With increasingly stringent environmental protection mandates worldwide, our polymer powders enable lower dosage requirements, faster flocs formation, and crystal-clear filtrate effluent.
Sub-sector Applications: Municipal Sewage Dewatering, Leather Tanning Waste, Paper Mill Effluent, Citric Acid Fermentation, Vegetable Protein Extraction, Dyeing & Finishing Plants, Pharmaceutical Wastewater, and Incense Manufacture.
In modern high-speed paper machinery, Oubo Polyacrylamide functions as a retention agent, drainage aid, wet/dry strength modifier, and white water clarifier.
Oubo Polyacrylamide plays a vital role in oilfield chemistry. It acts as an EOR mobility control polymer, drilling fluid fluid-loss reducer, shale inhibitor, friction reducer for hydraulic fracturing, and profile modification plugging agent.
In mineral processing, rapid solid-liquid phase separation is essential. Oubo PAM synthetic polymers aggregate solid mineral fines into massive fast-settling flocs during coal washing, tailings dewatering, and hydrometallurgical extraction of precious and base metals.
Target Minerals: Coal Washing & Tailings, Gold (Au), Silver (Ag), Iron (Fe), Nickel (Ni), Copper (Cu), Aluminum (Bauxite), and Uranium ores.
Sugar Industry: Food-grade anionic polyacrylamide ensures rapid juice clarification and floatation during sugarcane and sugar beet refining.
Textile Industry: Functions as a high-performance sizing agent, chemical finishing auxiliary, and heavy-duty fabric treatment agent preventing yarn breakage during high-speed weaving.
Oubo Chemical maintains complete supply chain security. All raw materials are procured from global petrochemical leaders including SINOPEC and Eni. Our fully automated packaging lines ensure moisture-proof, UV-resistant containment tailored for international sea freight.
Every consignment of Acrylamide monomer undergoes high-performance liquid chromatography (HPLC) testing before entering polymerization reactors.
Automated DCS systems control reaction temperature curves, molecular weight building, and hydrolysis levels with precision tolerances.
Prior to outbound shipment, QC engineers evaluate solubility, charge density, dynamic viscosity, and residual monomer levels 3 times.
All Oubo Chemical polymer products comply strictly with EU REACH registration standards, ISO 9001:2008 management protocols, and global environmental safety norms for industrial runoff discharge. Ultra-low acrylamide monomer residual options (<0.05%) are available for potable water and municipal applications.
We supply regional technical support and laboratory Jar Testing services across North America, South America, Southeast Asia, the Middle East, and Europe. Our engineering team assists buyers with PAM model selection, dissolution system design, and field dosage optimization.
Oubo is advancing eco-friendly bio-catalytic monomer synthesis, reducing greenhouse gas emissions per ton of polymer produced. Our ongoing investment (€2M/year) focuses on bio-degradable polymer modification and AI-guided real-time dosage telemetry devices.
Expert insights regarding Polyacrylamide selection, storage, application, and supply logistics from Oubo Chemical engineers.
The selection depends heavily on the surface electrical charge of the suspended particles in your wastewater or process stream. Inorganic solids (mineral tailings, clay, sand, river silt) carry negative charges and respond best to Anionic PAM (APAM). Organic biological sludge (municipal sewage, food processing waste) responds to Cationic PAM (CPAM) via charge neutralization. Acidic or variable salinity streams perform best with Nonionic PAM (NPAM). Laboratory benchtop Jar Testing is recommended prior to bulk procurement.
Polyacrylamide dry powder has a recommended shelf life of 24 months when stored in sealed original packaging inside a cool, dry, ventilated warehouse below 35°C. Avoid humidity and direct sunlight exposure to prevent moisture absorption and caking. Aqueous polymer solutions, once dissolved, should be used within 24 to 48 hours to prevent viscosity loss due to molecular chain degradation.
Unlike traditional chemical synthesis using acrylonitrile, Oubo uses patented micro-biological enzymatic synthesis to produce Acrylamide monomer. This yields higher monomer purity, zero toxic side-reaction impurities, lower energy consumption, ultra-high molecular weight distribution capabilities (up to 25 Million Daltons), and enhanced eco-friendliness.
