Explore our specialized range of high-efficiency polyacrylamide formulations engineered for industrial wastewater treatment, mineral recovery, and enhanced oil recovery.
Established in 2011 inside the Free Trade Zone of Qingdao, China, Qingdao Oubo Chemical Co., Ltd. (O'brien) has grown into a world-leading manufacturer and global exporter of high-performance Polyacrylamide (PAM). Operating with a strict ISO9001:2008 quality control system, Oubo has sustained an annual business growth rate of over 10% for more than a decade, reaching an annual capacity threshold exceeding 50,000 Metric Tons.
Utilizing proprietary bio-catalytic technology, Oubo produces acrylamide monomers at ambient temperatures with exceptional purity, minimal residual monomer (<250 ppm), and superior structural linearity for ultra-high molecular weight polymers.
Our supply chain integrates tier-1 global chemical suppliers including SINOPEC, Eni, and leading chemical producers to ensure baseline quality consistency across all synthesis cycles.
Investing over €2 Million annually into technical R&D, Oubo enforces a triple-stage QC testing protocol for every batch, validating molecular weight, hydrolysis degree, solubility rates, and charge density before dispatch.
Polyacrylamide (PAM, CAS 9003-05-8) is a synthetic, water-soluble polymer produced from the polymerization of acrylamide subunits. Anionic Polyacrylamide (APAM) is copolymerized with acrylic acid or functionalized via partial hydrolysis to introduce negative carboxylic groups (-COO⁻) along the polymer backbone.
APAM operates primarily through two distinct physical-chemical mechanisms: Charge Neutralization and Interparticle Polymer Bridging.
| Parameter | Standard Range | Industrial Impact |
|---|---|---|
| Molecular Weight (MW) | 6 - 25 Million Daltons | Determines bridging distance & floc shear strength |
| Hydrolysis Degree (Charge) | 5% - 80% Anionic | Governs charge neutralization affinity |
| Solid Content | ≥ 88% (Powder / Granule) | Active polymer concentration efficiency |
| Dissolution Time | 30 - 60 Minutes | Operational efficiency in automated make-up systems |
| Residual Monomer | ≤ 0.05% (500 ppm max) | Environmental compliance and non-toxicity safety |
Oubo Chemical's PAM product lineup offers tailored solutions across diverse industrial sectors globally. Below is an engineering breakdown of how our polymers optimize liquid-solid separation processes.
Essential for municipal wastewater clarification, industrial effluent treatment, and primary/secondary sedimentation tanks. APAM accelerates settling velocity in clarifiers and enhances dewatering efficiency when paired with inorganic coagulants (PAC/Alum).
Target Markets: Municipal Plants, Tannery Effluent, Chemical Processing, Vegetable Protein Extraction, Incense Production, and Pharmaceutical Wastewater.
Serves as a multi-functional wet-end chemical additive to increase process efficiency and paper quality.
Specially formulated high-viscosity APAM and NPAM act as rheology modifiers, friction reducers, and fluid loss control agents in complex geological formations.
Extensively applied in coal preparation plants, alumina production (Bayer process), red mud settling, and precious metal leaching (Gold, Silver, Copper, Iron, Nickel).
Rapidly clarifies wash water circuits, maximizes tailings thickener throughput, and yields dry filter cakes in vacuum disc filtration and belt filter presses.
Food-grade APAM polymers accelerate sugarcane and sugar beet juice clarification, separating non-sugar impurities, insoluble insolubles, and turbid suspended colloidal particles rapidly during lime clarification.
Used as a warp sizing agent to form a smooth, protective film on yarns, reducing breakages. In textile wastewater management, it removes heavy color dyes and organic loads when combined with decolorizing agents.
To preserve chemical stability, prevent hygroscopic caking, and accommodate international maritime freight standards, Oubo provides versatile packaging configurations engineered for global distribution.
Neutral, unbranded 25kg multi-wall kraft paper bags with inner PE moisture barrier liner. Ideal for OEM distributors and private-label buyers.
Standard O'Brien branded 25kg valve bags printed with batch numbers, net weight, production dates, and hazard-free transport iconography.
750kg - 1000kg heavy-duty woven polypropylene FIBC bulk bags designed for high-volume automated dosing systems and mining sites.
ISPM-15 compliant heat-treated wooden or plastic pallets. Standard loading: 1.0 - 1.2 Metric Tons per pallet, fully shrink-wrapped with corner boards.
For international procurement directors, chemical distributors, and engineering EPC contractors, selecting a Chinese APAM supplier requires evaluating total cost of ownership (TCO), quality consistency, compliance standards, and risk mitigation.
Raw material prices for acrylamide monomer (AM) track acrylonitrile (ACN) and upstream petrochemical indexes. Oubo Chemical maintains strategic raw material reserves and long-term contract pricing with SINOPEC and Eni. This buffers our global partners against short-term spot market surges, guaranteeing budget predictability and reliable lead times.
Located adjacent to the Qingdao Deepwater Port in the Free Trade Zone, Oubo leverages streamlined export customs clearances, offering expedited FCL (Full Container Load) shipments with typical port handling turnaround under 48 hours.
No two industrial wastewater streams are identical. Oubo's dedicated technical service team provides complimentary laboratory Jar Testing and polymer characterization services for global clients.
Customers can send water/sludge samples directly to our Qingdao laboratory. Our engineers determine the exact optimal polymer parameters: charge density, molecular weight, dissolution curve, and dosage rates (ppm), ensuring zero guesswork prior to commercial scale purchase orders.
As environmental regulations tighten globally (such as the EU Water Framework Directive and US EPA Effluent Guidelines), the demand for high-purity, environmentally compliant polyacrylamide formulations is accelerating.
Next-generation APAM products demand residual monomer levels below 250 ppm (0.025%) to meet potable water treatment regulations (NSF/ANSI Standard 60). Oubo's bio-enzymatic synthesis process suppresses acrylamide monomer residues to ultra-low levels, eliminating toxic byproduct accumulation.
For deep oilfield EOR and high-salinity industrial wastewater, conventional APAM chains undergo hydrolysis degradation and viscosity loss. Oubo is pioneering modified APAM copolymers incorporating temperature-resistant and salt-tolerant monomers (such as AMPS), maintaining solution viscosity up to 95°C in high-TDS brine environments.
Transitioning from manual powder preparation to fully automated continuous dissolution units prevents fisheye formation and polymer shear degradation. Oubo collaborates with dosing equipment manufacturers to provide turnkey chemical-plus-equipment packages.
Selecting the correct ionic polymer type is critical to achieving rapid sedimentation, clear supernatant, and maximum sludge dryness.
| Polymer Type | Ionic Charge | Optimal pH Range | Primary Industrial Target Sludge / Effluent | Primary Action Mechanism |
|---|---|---|---|---|
| APAM (Anionic) | Negative (-COO⁻) | 7.0 - 14.0 (Neutral to Alkaline) | Inorganic suspended solids, mineral tailings, sand washing, river silt, steel plant mill scale, clay suspensions. | High molecular weight bridging & electrostatic attraction to positive surfaces. |
| CPAM (Cationic) | Positive (-N⁺R₃) | 1.0 - 7.0 (Acidic to Neutral) | Organic sludge dewatering, municipal sewage, biological activated sludge, food processing, tannery waste. | Charge neutralization of negatively charged organic particles. |
| NPAM (Nonionic) | Neutral / Zero Charge | 1.0 - 8.0 (Highly Acidic) | Acidic wastewater, copper/zinc acidic leach solution, acidic mineral processing, soil stabilization. | Hydrogen bonding and physical polymer bridging. |
