Polyacrylamide (CAS 9003-05-8) is a synthetic, water-soluble linear resin synthesized through the free-radical polymerization of acrylamide monomers ($CH_2=CH-CONH_2$).
Synthesized by copolymerizing acrylamide with cationic monomers such as DAC (Acryloyloxyethyltrimethylammonium chloride) or DMC (Methacryloyloxyethyltrimethylammonium chloride). CPAM exhibits strong positive electrical charge densities ranging from 10% to 80% with molecular weights between 6 Million and 15 Million Daltons.
Produced via the copolymerization of acrylamide with acrylic acid or sodium acrylate, yielding negatively charged polymer chains. APAM features hydrolysis degrees spanning 5% to 60% and exceptionally high molecular weights ranging from 8 Million up to 25 Million Daltons.
Formed by pure homopolymerization of acrylamide, resulting in neutral polymers with minimal charge density (hydrolysis < 3%). NPAM exhibits high tolerance to extreme saline environments and low pH acidic liquid mediums.
| Polymer Type | Appearance | Molecular Weight (Million) | Charge Density / Hydrolysis | Solid Content (%) | Dissolving Time (Min) |
|---|---|---|---|---|---|
| Cationic (CPAM) | White Granular Powder | 6 - 15 Mw | 10% - 80% (Ionicity) | ≥ 89% | ≤ 60 Mins |
| Anionic (APAM) | White Granular Powder | 8 - 25 Mw | 10% - 60% (Hydrolysis) | ≥ 89% | ≤ 60 Mins |
| Nonionic (NPAM) | White Granular Powder | 5 - 15 Mw | 0% - 3% (Degree) | ≥ 89% | ≤ 90 Mins |
| Mannich PAM | Viscous Liquid / Powder | 4 - 10 Mw | 20% - 50% (Amine Grade) | ≥ 30% - 89% | ≤ 45 Mins |
Analyzing the macroeconomic trajectories, regulatory shifts, and commercial demand cycles governing water-soluble polymers through 2030.
Global regulatory bodies (including the US EPA, EU Water Framework Directive, and China's Environmental Protection Law) have drastically tightened permissible Total Suspended Solids (TSS) and Chemical Oxygen Demand (COD) limits. Municipal and industrial wastewater treatment plants are forced to adopt high-efficiency coagulants and cationic polyacrylamide flocculants to achieve rapid solid-liquid separation and lower sludge cake moisture content.
As global oilfields mature, tertiary recovery techniques rely heavily on ultra-high molecular weight Anionic Polyacrylamide (APAM) for polymer flooding. APAM increases water phase viscosity, improves sweep efficiency, and mobility ratio in reservoirs. Simultaneously, non-conventional shale gas hydraulic fracturing requires friction reducers manufactured from low-viscosity PAM emulsions.
Oubo Chemical provides customized PAM polymers optimized for specific hydrodynamic, pH, and ionic stress environments across diverse processing industries.
Polyacrylamide serves as the primary organic flocculating agent in industrial and municipal solid-liquid separation processes, encompassing sedimentation, clarification, thickening, and mechanical sludge dewatering.
For municipal sewage plants, high-charge Cationic Polyacrylamide (CPAM) destabilizes negatively charged colloidal sludge particles, inducing dense micro-floc formation suitable for belt filter presses, centrifuge decanters, and screw presses. In industrial sectors, Oubo PAM delivers high clarification rates across leather, paper mill effluent, citric acid processing, vegetable protein extraction, dyeing, pharmaceutical synthesis, and incense wastewater.




In wet-end paper chemistry, PAM acts as a multifunction chemical engine: retention agent, drainage aid, paper strength builder, and white water clarifier.
1. Retention & Drainage Aids: CPAM/APAM polymers retain short fibers and mineral fillers (PCC/GCC), enhancing wire drainage speed and cutting raw material losses.
2. Anionic Trash Catchers (ATC): Low Mw high-cationic polymers neutralize interfering anionic trash in closed-loop water systems.
3. Dry & Wet Strength Agents: Ionized polymer chains form covalent and hydrogen bonds directly with pulp cellulose hydroxyl groups.
4. Fiber Dispersants: Ultra-high Mw NPAM ensures uniform fiber distribution in specialty lightweight paper grades.




Polyacrylamide plays a critical role across upstream petroleum engineering sectors, including profile control, well plugging, drilling mud regulation, and hydraulic fracturing fluids.



Oubo offers a complete spectrum of Nonionic, Anionic, and Cationic polymers tailored for solid-liquid separation across coal preparation and precious metal extraction.



Specifically purified food-grade APAM polymers accelerate sugarcane juice clarification and syrup flotation. By binding mud impurities into rapid-settling flocs, Oubo PAM improves sugar yield and juice clarity without leaving harmful residues.
Serves as an effective textile sizing agent, fabric finishing aid, and dye-house wastewater decolorizer. PAM increases warp sizing adhesion, reduces yarn breaking rates during weaving, and efficiently coagulates recalcitrant azo dye complexes in wastewater streams.
