The global chemical market is rapidly phasing out traditional chemical-catalyst acrylamide synthesis in favor of 3rd-generation biological enzymatic conversion. Biological methods eliminate toxic copper residue, yield higher molecular weight polymers (up to 30 Million Daltons), and drastically reduce energy consumption during polymerization.
Industrial sectors face unprecedented regulatory pressures regarding zero liquid discharge (ZLD). High-charge density flocculants are increasingly mandated to optimize solid-liquid separation, reduce sludge volume, and lower operating costs in municipal and heavy industrial effluent treatment plants.
As mature oil reserves decline, Enhanced Oil Recovery (EOR) utilizing ultra-high molecular weight water-soluble polymers is critical for maintaining reservoir pressure and sweep efficiency. Thermal-stability and salt-resistant PAM variants represent the leading edge of energy chemical procurement.
Securing a resilient supply of synthetic polyacrylamide requires robust upstream integration, raw material availability, and intelligent manufacturing protocols. Qingdao Oubo Chemical leverages China's modern industrial ecosystem to deliver world-class reliability.
Our raw material procurement is backed by long-term strategic alliances with global petrochemical leaders, including SINOPEC and Eni. By securing top-tier Acrylonitrile (AN) feedstocks, Oubo ensures monomer purity exceeding 99.9%, directly preventing polymer chain termination and guaranteeing structural batch-to-batch consistency.
Located inside the Qingdao Free Trade Zone, Oubo benefits from immediate access to one of the world's largest deep-water shipping hubs. Every production batch undergoes triple-testing by our dedicated QC laboratory prior to shipment.
Polyacrylamide (CAS 9003-05-8) is a synthetic resin prepared by polymerizing acrylamide monomer unit chains. As a water-soluble polymer, its efficacy as a flocculant, coagulant, or rheology modifier is governed by physical form, molecular weight (MW), and ionic charge type.
| Polymer Type | Ionic Charge Density | Molecular Weight (MW) | Primary Industrial Applications | Key Operational Benefit |
|---|---|---|---|---|
| Anionic PAM (APAM) | Low to High (5% - 60%) | High to Ultra-High (8M - 25M) | Municipal Wastewater, Mineral Processing, Paper Wet End, EOR | Superior bridging mechanism in neutral to alkaline pH suspensions. |
| Cationic PAM (CPAM) | Low to Very High (10% - 80%) | Medium to High (6M - 15M) | Organic Sludge Dewatering, Textile Effluent, Belt Press Dewatering | Neutralizes negatively charged organic particles for dense flocs. |
| Nonionic PAM (NPAM) | Near Zero (< 1%) | Medium to High (5M - 12M) | Acidic Wastewater, Soil Conditioning, Oilfield Drilling Fluid | High salt and extreme acid tolerance without charge neutralization loss. |
| Amphoteric / Mannich | Dual Cationic/Anionic | Variable (4M - 10M) | Complex Refractory Effluent, High-Salinity Sludge Systems | Dual-action charge balancing for difficult industrial effluents. |
We supply granular powder, micro-emulsion, and solution polymers packaged to international industrial standards.
Polyacrylamide acts as a primary flocculant in solid-liquid separation processes, including sedimentation, clarification, thickening, and sludge dewatering. Increasingly stringent global environmental regulations drive the demand for rapid flocs settlement.
Specific Industry Verticals: Municipal sewage treatment, leather processing, paper making effluents, citric acid production, vegetable protein extraction, dyeing processes, pharmaceutical wastewater, incense manufacturing, and sugar mill effluent.
Primary Function: Promotes micro-floc aggregation into robust macro-flocs capable of surviving high-shear belt presses, centrifuge decanters, and screw presses.







In paper manufacturing, PAM serves multi-functional roles to enhance sheet quality, reduce fiber loss, and improve machine runnability:
Polyacrylamide is indispensable in modern oilfield engineering, serving as a fluid loss control agent, shale inhibitor, viscosity modifier, friction reducer, and profile plugging polymer.






Oubo provides tailored anionic, cationic, and non-ionic polymers of varied molecular weights engineered specifically for hydrometallurgy and ore separation:
Optimized anionic polymers enhance juice clarification and syrup flotation during cane and beet sugar extraction, accelerating mud settling while preserving sucrose purity.


Functions as a warp sizing agent, anti-static agent, and fabric finishing component. In wastewater plants, CPAM decouples complex dye complexes from liquid effluent.
