Established in 2011 within the strategic Free Trade Zone of Qingdao, China, Qingdao Oubo Chemical Co., Ltd has grown to become a globally distinguished pioneer in the synthesis and industrial formulation of Polyacrylamide (PAM). Powered by advanced fully automated production lines, patented bio-catalytic synthesis routes, and an unyielding commitment to environmental sustainability, Oubo Chemical delivers high-tier polymer solutions across over 60 countries.
Operating under the internationally recognized registered brand O'brien, our facility achieved a monumental milestone by surpassing an annual production capacity of 50,000 Metric Tons in 2018. Over the past decade, our business has sustained a steady annual growth rate of 10%, grounded in our ISO9001:2008 certified Quality Management System and rigorous three-stage pre-shipment testing protocols.
Oubo Chemical integrates a fully synchronized global raw material supply chain, sourcing top-tier chemical monomers from industry titans such as SINOPEC and Eni. Our R&D division invests over €2 Million annually into advanced polymer architecture research, pushing the boundaries of temperature resistance and shear stability for oilfield polymer flooding and industrial clarification.
Understanding the structural, rheological, and chemical advantages of specialized polymer chains engineered for extreme reservoir conditions.
Polyacrylamide (PAM) is a linear water-soluble polymer synthesized from acrylamide monomers ($\text{CH}_2=\text{CHCONH}_2$). For oil-grade applications, molecular weights are precisely scaled from 5 Million up to 30 Million Daltons.
Our advanced Hydrolyzed Polyacrylamide (HPAM) features partially hydrolyzed carboxylate groups ($\text{-COO}^-$) along the backbone, inducing electrostatic repulsion that uncoils the polymer chain. This expanded hydrodynamic volume dramatically increases water viscosity even at low concentrations.
In Tertiary Oil Recovery (EOR), maintaining ideal mobility ratios between injected water and crude oil is vital. Oubo's oil-level PAM demonstrates non-Newtonian, shear-thinning (pseudoplastic) behavior.
Under high shear forces inside injection pumps and wellbores, viscosity dynamically lowers to reduce pumping energy. Once entering porous rock formations, low shear rates cause instantaneous viscosity recovery, effectively preventing viscous fingering and maximizing sweep efficiency.
Standard polymers degrade in harsh subterranean environments rich in divalent ions ($\text{Ca}^{2+}$, $\text{Mg}^{2+}$) and elevated temperatures. Oubo solves this via modified Hydrophobically Associated PAM (HAPAM) and copolymers incorporating 2-Acrylamido-2-methylpropanesulfonic acid (AMPS).
AMPS monomers introduce strongly acidic sulfonate groups that remain fully ionized across wide pH ranges, resisting divalent ion precipitation up to 120°C and 200,000 ppm TDS salinity.

How Oubo Chemical's targeted ionic series (Anionic, Cationic, Nonionic, Mannich) deliver performance across global sectors.
Polyacrylamide plays an indispensable role throughout the lifecycle of oil and gas assets. Beyond polymer flooding for Enhanced Oil Recovery (EOR), our specialty polymers perform as critical drill mud additives, shale inhibitors, friction reducers, and profile plugging agents.
Increasingly stringent global environmental mandates require powerful flocculating agents capable of clarifying complex aqueous effluents. Oubo PAM aggregates suspended solids into dense, rapidly settling flocs.
In wet-end paper manufacturing chemistry, Oubo Polyacrylamide functions as a multi-functional performance chemical, enhancing structural integrity and machine runnability.
Efficient mineral extraction requires high-rate thickeners and rapid tailings clarification. Oubo's nonionic and anionic series optimize hydrometallurgical solid-liquid separation.
Food-grade high-purity Anionic Polyacrylamide is utilized during raw sugar juice clarification, flotation processes, and vegetable protein extraction. Rapid sediment compaction ensures high juice clarity, reduced sugar loss, and maximized yield per ton of cane or beet.
PAM acts as a versatile sizing agent and fabric finishing treatment that improves yarn smoothness and weaving efficiency. In dye house effluent facilities, specialized cationic formulations coagulate hydrophobic and reactive dye molecules, reducing COD and color turbidity prior to discharge.
Why global chemical distributors, oilfield service majors, and industrial leaders choose Qingdao Oubo Chemical as their primary manufacturing partner.
We utilize state-of-the-art biological enzymatic methods to convert Acrylonitrile to Acrylamide. This patented zero-byproduct process guarantees lower residual monomer levels (<0.05%) and higher chemical purity compared to traditional copper-catalyzed routes.
Strategic long-term bulk procurement contracts with global energy giants like SINOPEC and Eni ensure uninterrupted raw material supply, shielding our clients from global monomer price volatility.
From polymer gel polymerization, hydrolysis, drying, and granulation to automated packaging, our modern production lines operate under strict DCS system control, minimizing human error and batch-to-batch variation.
Located inside the Qingdao Free Trade Zone, our facility is minutes away from Qingdao Port—one of the largest deep-water shipping hubs in the world—enabling rapid container loading, fast customs clearance, and reduced maritime transit times.

Optimizing Total Cost of Ownership (TCO) through accurate polymer matching, lab dosage testing, and localized field support.
Selecting the ideal polymer requires evaluating slurry Zeta Potential. Highly organic sludges (e.g., municipal sewage) demand high-charge Cationic PAM. Inorganic mineral suspensions require Anionic or Nonionic polymers with high molecular weights to achieve optimal bridging flocculation.
Polyacrylamide dry powders require proper dispersion to avoid "fish-eyes" (undissolved gel agglomerates). We recommend installing automatic mechanical dosing units with low-shear impellers, maintaining a 0.1%–0.3% concentration matured for 45–60 minutes prior to injection.
Oubo Chemical’s technical engineers collaborate directly with procurement teams. We provide complimentary laboratory jar testing and field sample analysis, determining exact dosage rates (ppm) to lower chemical consumption costs by up to 20%.
