Oubo Chemical Co., Ltd was established in 2011, strategically located in the Free Trade Zone of Qingdao, China. Operating as an industry-leading manufacturer and exporter of water-soluble polymers, Oubo Chemical maintains a world-class Quality Control (QC) infrastructure. Over the past decade, our enterprise has sustained an annual business growth rate exceeding 10% per year. Qingdao Oubo Chemical Co., Ltd is rigorously committed to product purity, application precision, operational safety, and environmental stewardship throughout polymer synthesis and industrial field application.
Oubo specializes in synthesizing and formulating Cationic Polyacrylamide (CPAM), Anionic Polyacrylamide (APAM), and Nonionic Polyacrylamide (NPAM). Utilizing state-of-the-art automated polymerization reactors and backed by a senior scientific team, we ensure all chemical products and technical services adhere to exacting global standards. In 2018, Oubo's annual production capacity broke through 50,000 Metric Tons, supported by an international ISO9001:2008 Quality Management System certification. We proudly stand behind every chemical batch delivered across six continents.
Qingdao OUBO Chemical Co., Ltd is a world pioneer in utilizing advanced biological enzymatic methods to synthesize high-purity acrylamide monomers. Our proprietary bio-catalytic process—protected by international patents—operates at mild reaction temperatures, dramatically eliminating toxic micro-byproducts such as free acrylamide monomer (ATT < 0.05%), ensuring unmatched polymer cross-linking stability and safety in environmental applications.
We source ultra-pure chemical feedstocks globally, establishing strategic procurement alliances with petrochemical giants including SINOPEC and Eni. Every automated manufacturing line at Oubo is integrated with real-time process control sensors. Our rigorous 3-tier QC verification system inspects chemical properties raw-material-in, during synthesis, and post-packaging prior to shipment clearance.
With 8+ years of deep domain expertise in synthetic resin chemistry, Oubo’s senior chemical engineers support buyers from pre-sales laboratory jar testing to full-scale plant integration. We customize molecular weight (MW: 3 Million to 22 Million) and charge density (5% to 80%) to match client-specific equipment, substrate constraints, and regional water profiles.
Our corporate strategy is centered around continuous performance optimization aligned with global carbon neutrality targets. By refining polymer dissolution efficiency and reducing operational dosing dosages, Oubo empowers industrial clients to minimize chemical footprints, treat complex effluents, and safeguard global aquatic ecosystems.
In modern textile engineering, Polyacrylamide (PAM) serves as a vital functional chemical polymer. Operating as an advanced synthetic thickener, rheology modifier, sizing auxiliary, and wastewater clarifying agent, high-performance PAM formulations are critical for high-resolution pattern definition, color yield optimization, and high-efficiency wastewater treatment in textile printing mills worldwide.
Textile printing—whether flatbed screen printing, rotary screen printing, or high-speed roller printing—requires printing pastes to exhibit non-Newtonian pseudoplastic (shear-thinning) fluid behavior. Polyacrylamide synthetic thickeners deliver superior rheological control compared to traditional natural gums (such as sodium alginate or starch derivatives):
Different textile substrates and dye classes demand tailored polyacrylamide chemistry. Oubo Chemical provides customized PAM polymer series optimized for specific printing operations:
| Application Sector | Recommended PAM Type | Molecular Weight (Million) | Key Technical Advantage |
|---|---|---|---|
| Pigment Screen Printing | Anionic PAM (APAM) / Nonionic PAM | 12 - 18 MW | High electrolyte stability, smooth paste flow, prevents screen clogging, sharp outline clarity. |
| Reactive Dye Printing (Cotton/Cellulose) | Modified Nonionic PAM (NPAM) | 8 - 14 MW | Excellent paste stability in high-alkali formulations; high washability without stiff fabric hand-feel. |
| Warp Sizing & Textile Finishing | Anionic PAM (APAM) | 10 - 15 MW | Forms a flexible, smooth film on yarns; reduces warp breakage in high-speed weaving looms. |
| Printing & Dyeing Wastewater Flocculation | Cationic PAM (CPAM CAS 9003-05-8) | 8 - 12 MW (High Charge 30-60%) | Rapid charge neutralization of negative dye particles, rapid decolorization, and sludge dewatering. |
Textile printing and dyeing effluents are notoriously difficult to clarify due to high chemical oxygen demand (COD), intense chromicity (color index), dynamic pH shifts, and recalcitrant organic auxiliaries. Oubo's specialized Cationic Polyacrylamide (CPAM) flocculants feature high charge density to effectively destabilize colloidal dye suspensions:
Beyond printing pastes, Oubo Chemical manufactures tailored polyacrylamide grades engineered for critical global industries.
As a key flocculating agent used extensively in municipal sewage treatment and industrial solid-liquid separation processes (settlement, clarification, concentration, and sludge dewatering). Increasingly stringent global environmental regulations promote continuous demand for our advanced cationic and anionic flocculants across leather, citric acid, pharmaceutical, and municipal sectors.


Functions as wet/dry strength agents, retention aids, filter aids, and anionic trash catchers in papermaking. Enhances paper physical strength, lowers fiber loss, cleans recycled white water, and accelerates pulp dewatering:



Widely applied in oil exploration, profile control, plugging agents, shale fracturing fluids, and drilling fluid loss additives. Plays a vital role in viscosity control, shale inhibition, lubricating drill bits, carrying cuttings, and Enhanced Oil Recovery (EOR):



Essential for solid-liquid separation, tailings dewatering, and slurry settling across gold, silver, copper, iron, nickel, alumina, and coal processing plants. Facilitates rapid sedimentation in thickeners, filtration speedups, and subterranean pipe sealing.



High-purity anionic polyacrylamide flocculants accelerate juice clarification, flotation, and mud settling during sugarcane and sugar beet refining, improving sugar yield and clarity while meeting stringent food-contact impurity standards.


Strategic perspectives on global chemical sourcing, Total Cost of Ownership (TCO), and sustainable polyacrylamide innovations.
Global demand for water-soluble synthetic polymers is expanding rapidly, driven by strict ESG compliance mandates, industrial water recycling loops, and growth in digital/screen textile printing in Southeast Asia, Latin America, and EMEA. International buyers prioritize chemical suppliers capable of delivering multi-container consistency, long-shelf-life stability, zero monomer toxicity, and reliable bulk logistics flexibility.
Oubo Chemical’s research center invests over €200 Million in polymer synthesis breakthroughs. Our core development roadmap focuses on: 1) Bio-catalytic zero-residual acrylamide monomers; 2) Micro-emulsion PAMs with sub-30-second dispersion rates; 3) Ultra-high shear resilient thickeners for textile digital printing inks; 4) Biodegradable polyacrylamide co-polymers.
