Explore our high-purity, application-specific PAM formulations produced via advanced biological enzymatic synthesis for oilfield operations and industrial water management.
Qingdao Oubo Chemical Co., Ltd — Global Pioneer in High-Molecular-Weight Water-Soluble Polymers for Harsh Industrial Environments.
Established in 2011 and strategically operating within the Free Trade Zone of Qingdao, China, Qingdao Oubo Chemical Co., Ltd has developed into an internationally recognized titan in water-soluble synthetic resin manufacturing. With a steady annual business growth rate exceeding 10% year-on-year over the past decade, our production footprint is anchored by rigorous quality control systems and sustainable environmental engineering.
By 2018, Oubo’s annual polyacrylamide production capacity officially broke through 50,000 Metric Tons. Our comprehensive enterprise quality management infrastructure is certified under ISO 9001:2008. We take immense pride in delivering precision chemical agents that balance chemical efficacy, economic viability, and minimal ecological footprint.
Unlike traditional chemical synthesis routes that produce higher residual acrylamide monomer impurities, Oubo utilizes proprietary biological enzymatic methods for polymerizing acrylamide. We hold key national patents for this clean synthesis technology.
To maintain our competitive advantage, Oubo re-invests over €200 million annually into research and development. Our strategic supply chain incorporates global raw material sourcing from elite chemical conglomerates including SINOPEC, Eni, and other Tier-1 suppliers. Every batch undergoes 3-stage Quality Control testing prior to global dispatch.

Maximizing Sweep Efficiency, Shale Inhibition, Friction Reduction, and Reclaimed Water Recirculation in Modern Upstream Petroleum Engineering.
In mature oil fields, tertiary recovery relies heavily on High-Molecular-Weight Partially Hydrolyzed Polyacrylamide (HPAM). By increasing the viscosity of injected displacement water, HPAM optimizes the mobility ratio between oil and water phases, suppressing viscous fingering. Oubo’s oilfield polymers are engineered to maintain structural shear stability under high temperatures (>90°C) and elevated salinity conditions.
During deep well drilling and horizontal hydraulic fracturing, our specialized Nonionic and Anionic PAM grades serve as ultra-efficient viscosifiers and friction reducers. They lower pipe friction losses by up to 70%, encapsulate drill cuttings for rapid transport to the surface, stabilize reactive shale formations, and reduce fluid filtration loss into sensitive payzones.
Oilfield produced water contains complex emulsions of free hydrocarbons, suspended solids, and dissolved organic compounds. Oubo's tailored Cationic and Amphoteric flocculants break stubborn micro-emulsions, allowing rapid phase separation for reinjection or Zero Liquid Discharge (ZLD) treatment facilities.
From municipal environmental preservation to heavy industrial manufacturing, Oubo Polyacrylamide provides versatile solid-liquid separation and fluid modification capabilities.
As a premier flocculating agent, Polyacrylamide is mainly utilized in industrial solid-liquid separation processes, including primary settlement, clarification, liquor concentration, and high-pressure sludge dewatering. Increasingly stringent global environmental protection standards continue to drive technological innovation in water treatment chemical systems.
For municipal sewage treatment plants, Oubo PAM is widely employed alongside applications in leather tanning, papermaking, citric acid production, vegetable protein extraction, textile dyeing, pharmaceuticals, incense manufacturing, and petrochemical refining effluents.
Municipal Water Clarification
Industrial Dewatering Centrifuge
Petrochemical Effluents
High-Rate Sedimentation
In the paper manufacturing process, Oubo Polyacrylamide functions as an indispensable dry strength agent, retention aid, and filtration accelerator. It substantially enhances paper sheet physical strength, minimizes fine fiber and filler loss through the wire mesh, aids white water clarification, and optimizes flotation de-inking operations.
Wet End Chemical Dosing
Retention & Drainage
Polyacrylamide plays a critical role in mineral beneficiation, hydrometallurgical extraction, and tailings management. By aggregating fine mineral slurries into large, dense flocs, it enables rapid thickening and filtration across various ore types:
Coal Washing Thickening
Mineral Tailings Dewatering
Base Metal Slurry Separation
PAM is extensively applied as a full-performance textile sizing agent, finishing auxiliary, and fabric treatment component. It increases warp yarn strength, reduces breakage rates during high-speed weaving, and clarifies high-COD, heavily colored textile dyeing effluents.
Textile Processing
Dyeing Wastewater
In sugar cane and sugar beet manufacturing, specialized food-grade Polyacrylamide acts as an effective clarification and flotation agent, rapidly settling juice impurities without leaving hazardous residual monomers in the refined product stream.
Sugar Juice Clarification
Food Effluent Separation
Unrivaled Quality Assurance, Competitive Cost Structure, and Seamless Logistics from Qingdao Port to Global End-Users.
Our raw material procurement network is fully integrated with global petrochemical leaders like SINOPEC and Eni. Automated DCS control systems monitor reaction temperature, pressure, and initiator dosing in real time. Every batch is tested 3 times (Raw Material, Synthesis Gel, Finished Dry Powder) by our in-house QC laboratory prior to release.
Located directly within the Qingdao Free Trade Zone, Oubo benefits from immediate proximity to Qingdao Port—one of the world's largest deep-water chemical shipping hubs. This location cuts inland logistics overhead, ensures steady container availability, and guarantees rapid dispatch to North America, the Middle East, South America, and Europe.
Tailoring Molecular Weights and Ionic Charge Densities to Regional Environmental Standards and Reservoir Conditions.
Middle East & North Africa: High-salinity, high-temperature oilfields require thermal-resistant modified HPAM co-polymers containing ATBS monomers to prevent thermal hydrolysis degradation downhole.
North American Shale Basins: Unconventional hydraulic fracturing demands ultrafast-dissolving slickwater friction reducers capable of dispersing completely within 30 seconds under high shear rates.
European Union: Municipal wastewater standards mandate extremely low free-acrylamide monomer residual content (<250 ppm or <100 ppm) for compliance with REACH and local water safety guidelines.
Bio-Based & Eco-Friendly Monomers: Transitioning towards greener enzymatic synthesis to reduce energy consumption and environmental impact during polymer manufacturing.
Micro-Emulsion Technology: Liquid emulsion polyacrylamides providing instant dissolution without dust generation, enabling automated online continuous dosing equipment.
