High-performance water treatment chemicals synthesized via eco-friendly biological methods
Global presence, robust quality control system, and sustainable polymer innovation since 2011
Anionic Polyacrylamide (APAM) is a linear, water-soluble high-molecular-weight polymer synthesized via the copolymerization of acrylamide monomers and acrylic acid (or sodium acrylate) functional groups. Recognized globally as a premier synthetic resin and flocculating agent, APAM features a distinct molecular chain characterized by negatively charged carboxylate groups ($\text{-COO}^-$) along its hydrocarbon backbone. This dynamic ionic architecture enables high-performance charge neutralization, inter-particle bridging, and efficient solid-liquid separation across challenging industrial environments.
As a dedicated Anionic Polyacrylamide Supplier, Qingdao Oubo Chemical Co., Ltd. (established in 2011 within the Free Trade Zone of Qingdao, China) leverages state-of-the-art bio-catalytic enzymatic technology for monomer production. Unlike conventional chemical synthesis methods, bio-catalytic polymerization yields high-purity acrylamide monomers with negligible residual acrylamide monomer (MAM) content, exceptionally high molecular weights (ranging from 5 Million to upwards of 25 Million Daltons), and customizable charge densities (ranging from 10% to 80% anionic hydrolysis degree).
The performance efficacy of Anionic Polyacrylamide in industrial applications is primarily governed by two structural parameters: Molecular Weight (MW) and Degree of Hydrolysis (Charge Density).
| Grade Classification | Molecular Weight (Million) | Hydrolysis Degree (%) | Solid Content (%) | Dissolution Time (Mins) | Primary Industrial Application |
|---|---|---|---|---|---|
| APAM Ultra-High MW | 20.0 – 25.0 | 20% – 30% | ≥ 88% | ≤ 60 | EOR (Enhanced Oil Recovery), Tailings Dewatering |
| APAM High MW | 15.0 – 20.0 | 25% – 40% | ≥ 88% | ≤ 50 | Municipal Sewage, Industrial Wastewater Coagulation |
| APAM Medium MW | 10.0 – 15.0 | 15% – 30% | ≥ 88% | ≤ 45 | Paper Retention & Drainage, Sugar Juice Clarification |
| APAM Low MW | 5.0 – 8.0 | 10% – 20% | ≥ 88% | ≤ 30 | Dispersant Agents, Acidic Wastewater Clarification |
Delivering consistent polymer chemistry through global supply chain integration and rigorous testing
To guarantee absolute batch-to-batch polymer purity, Oubo Chemical procures high-grade primary raw materials from world-class petrochemical leaders, including SINOPEC and Eni. Fully automated continuous polymer production lines eliminate human error during batching and polymerization.
Oubo operates under a strict, comprehensive quality control system certified by ISO9001:2008. Every single batch of product undergoes 3 separate, mandatory quality verification steps by our dedicated QC team before leaving the facility: raw material assay, reactor output check, and final packaged powder testing.
Oubo invests €200 Million annually into continuous technical research and technology accumulation. Our patented biological monomer synthesis reduces energy consumption, minimizes carbon impact, and yields polyacrylamide with longer molecular chains and enhanced shear resistance.
Tailored Polyacrylamide formulations for diverse sector challenges worldwide
In municipal sewage treatment and industrial solid-liquid separation, APAM functions as a premier primary flocculant. It significantly accelerates sedimentation kinetics, clarifies turbid water, and promotes high-solids sludge compaction in belt filter presses, centrifuges, and chamber filter presses.
APAM plays a pivotal role in Enhanced Oil Recovery (EOR) by increasing the viscosity of injected water, thereby improving sweep efficiency across reservoir zones. It serves as an essential fluid-loss control additive, shale inhibitor, friction reducer, and profile plugging agent in drilling muds and hydraulic fracturing fluids.
Acts as a retention aid, drainage agent, and wet/dry strength agent. APAM neutralizes anionic trash, balances wet-end chemistry, increases retention rates of short fibers and mineral fillers (TAC/PCC), improves sheet formation, and enhances white water recycling efficiency.
Provides rapid solid-liquid separation during mineral dressing for gold, copper, iron, nickel, aluminum, and coal washing tailings. APAM accelerates clear water recovery from thickeners and reduces tailing pond environmental footprint dramatically.
Optimized food-grade anionic flocculants accelerate juice clarification and sugar liquor flotation. It removes suspended organic impurities rapidly without leaving hazardous chemical residues in the final refined sugar product.
Utilized as a textile warp sizing agent, fabric finishing agent, and protective coating layer. In dye house wastewater treatment, APAM removes heavy color intensity and suspended solids when combined with inorganic coagulants like PAC.
As environmental regulations tighten across Europe, North America, and Asia-Pacific, Oubo Chemical continues to advance its polymer chemistry roadmap. Our forward-looking development focuses on low-monomer toxicity, hyper-branched salt-tolerant polymers, and green bio-degradable chemical frameworks.
Traditional polyacrylamide manufacturing relies on chemical synthesis using copper-catalyzed hydration of acrylonitrile. This older methodology often leaves copper catalyst trace residues and higher unreacted acrylamide monomer (MAM) concentrations, which pose toxicological risks to aquatic ecosystems.
Oubo Chemical’s microbial enzymatic bio-catalysis process utilizes specialized biological enzymes to convert acrylonitrile into acrylamide monomer at room temperature. This yields an exceptionally pure monomer solution with zero heavy metal contamination, extremely low monomer residue (< 500 ppm), and longer linear molecular structures capable of achieving superior flocculation efficiency at lower dosage rates.
To ensure safe, moisture-proof transport across oceanic and land routes, Oubo offers standardized and customized packaging solutions designed for global supply security:
