Established in 2011, Oubo Chemical Co., Ltd is strategically headquartered within the Free Trade Zone of Qingdao, China—a global nexus for chemical logistics and maritime transport. Over the past decade, Oubo Chemical has maintained an extraordinary growth trajectory of over 10% annually, establishing itself as a world-leading manufacturer and wholesale supplier of synthetic water-soluble polymers, primarily focused on Anionic Polyacrylamide (APAM), Cationic Polyacrylamide (CPAM), and Nonionic Polyacrylamide (NPAM).
Operating under our internationally recognized flagship brand O'brien, our manufacturing facilities integrate state-of-the-art biological enzyme polymerization technology, setting an industry benchmark for low residual monomer content, high molecular weight control, and unmatched eco-efficiency. In 2018, Oubo Chemical reached a historic operational milestone, exceeding an annual polyacrylamide production capacity of 50,000 Metric Tons. Our entire infrastructure is rigorously certified under the ISO 9001:2008 Quality Management System, guaranteeing that every ton of polymer leaving our factories delivers pristine consistency, precise charge density, and optimal performance across demanding industrial environments.
Polyacrylamide (CAS 9003-05-8) is a linear synthetic polymer derived from acrylamide monomers. In its anionic configuration (Anionic Polyacrylamide / APAM), the polymer backbone incorporates negatively charged carboxylate groups, typically generated through the copolymerization of acrylamide with sodium acrylate or via the partial hydrolysis of polyacrylamide homopolymers.
Oubo Chemical produces APAM with ultra-high molecular weights ranging from 6 Million to 25 Million Daltons. High molecular weight polymers extend long molecular chains into solution, creating extensive physical bridges between suspended colloidal particles to accelerate sedimentation.
The degree of hydrolysis (anionic charge density) varies from 10% to 50%. This variable charge allows precise customization according to substrate electrical characteristics, optimizing electrostatic repulsion reduction and floc formation in high-turbidity mineral slimes and industrial waste streams.
APAM functions through two synergistic mechanics: Charge Neutralization (reducing zeta potential on positively charged suspended solids) and Interparticle Bridging (adsorbing onto multiple particles simultaneously to form heavy, rapidly settling macro-flocs).
| Polymer Grade | Ionic Nature | Molecular Weight (Million) | Degree of Hydrolysis (%) | Solid Content (%) | Dissolving Time (Min) |

| Oubo APAM-Ultra High | Anionic | 22 - 25 | 25 - 35% | ≥ 88% | ≤ 60 |
| Oubo APAM-Medium MW | Anionic | 10 - 15 | 15 - 25% | ≥ 88% | ≤ 50 |
| Oubo CPAM Series | Cationic | 8 - 12 | 10 - 60% (Ionicity) | ≥ 89% | ≤ 45 |

China has evolved into the global epicenter for synthetic polymer production. Within this ecosystem, Qingdao Oubo Chemical Co., Ltd. stands out by combining regional supply chain advantages with rigorous proprietary technological innovations.
Unlike traditional chemical synthesis that relies on copper catalysts (which leave toxic trace heavy metals), Oubo utilizes advanced biological enzymatic methods for monomer synthesis. This proprietary process yields ultra-pure Acrylamide monomer, preventing cross-branching, reducing residual monomer content below 0.05%, and enabling ultra-high molecular weight chain formation.
Quality begins at the monomer level. Oubo Chemical maintains strategic global supply chain partnerships with world-class petrochemical leaders such as SINOPEC and Eni. By securing top-tier raw materials, we guarantee batch-to-batch chemical stability across all 50,000 tons of annual output.
Our Quality Control system is unyielding. Every batch undergoes a rigorous 3-stage validation protocol: incoming raw material purity testing, real-time automated inline polymerization monitoring, and pre-shipment laboratory analysis (dissolution rate, filterability, and active content verification).
Located inside the Free Trade Zone of Qingdao, our factory offers direct port access, streamlined customs clearance, and reduced maritime transit times. This strategic geographical placement ensures competitive wholesale pricing and rapid international container vessel departures.
Selection of ionic charge configurations formulated to optimize liquid-solid separation in neutral, acidic, or alkaline liquid media.
Tailored for organic sludge dewatering, municipal wastewater, belt-filter presses, and centrifuge operations requiring strong charge neutralization.
Ideal for high-density inorganic mineral suspensions, metallurgical wastewater, coal washing, and tertiary Enhanced Oil Recovery (EOR).
Designed for highly acidic wastewater streams, textile finishing agents, and specialized soil stabilization applications where ionic interference must be avoided.
As environmental regulations tighten globally, industrial demand is shifting toward eco-friendly, ultra-high efficiency polymer coagulants and flocculants.
Industrial enterprises are mandated to recycle up to 98% of process water. High molecular weight APAM accelerates clarification in high-speed thickeners, allowing rapid water recovery and closed-loop reuse in power generation, mining, and chemical processing.
Stringent potable water standards (such as NSF/ANSI 60) demand residual acrylamide monomer (AMD) levels below 0.05% (500 ppm). Oubo Chemical’s enzymatic synthesis ensures compliance with strict toxicity mandates for municipal drinking water treatment.
With mature oilfield yields declining, polymer-flooding EOR relies on shear-resistant APAM with high temperature and salinity stability to optimize sweep efficiency and mobilize trapped hydrocarbons.
Oubo Polyacrylamide solutions provide targeted molecular performance tailored to distinct operational parameters across global heavy industries.
As a primary synthetic flocculant, APAM and CPAM are essential in industrial solid-liquid separation processes, including primary clarification, sedimentation, sludge thickening, and centrifuge dewatering. Increasingly stringent discharge regulations drive municipalities and plant operators to adopt Oubo high-charge polymers for crystal-clear effluent streams.
Major sectors include urban sewage plants, leather tanneries, paper mill wastewater, citric acid processing, vegetable protein extraction, pharmaceutical synthesis, incense manufacture, and textile dyeing effluent.
In paper mills, Polyacrylamide serves as a retention aid, drainage promoter, and dry/wet strength enhancement agent. By adding small quantities of tailored APAM or CPAM to the wet end, mills significantly improve fiber retention, lower raw material consumption, and optimize white-water loop recycling.
Polyacrylamide is heavily utilized across upstream oil & gas fields for profile modification, water-plugging agents, hydraulic fracturing fluid additives, and shale stabilizing drilling muds. It acts as a friction reducer, fluid loss control additive, and drill bit lubricant.
