A Decade of Excellence in Polymer Manufacturing, Bio-Catalytic Synthesis, & Global Environmental Stewardship
Oubo Chemical Co., Ltd was established in 2011, strategically located in the Free Trade Zone of Qingdao, China. Over the past decade, our business growth rate has maintained a steady trajectory of 10% per year. As a premier global manufacturer, Qingdao Oubo Chemical Co., Ltd is deeply committed to precision quality control, customer-centric engineering service, and environmental sustainability throughout polymer synthesis and field application.
We utilize patented biological enzymatic methods to produce acrylamide monomers and polyacrylamide polymers. This cutting-edge bio-catalytic process operates under ambient temperature, significantly reducing carbon emissions, preventing side reactions, and yielding polymers with high purity, ultra-high molecular weight, and ultra-low residual monomer content (< 0.05%). With continuous infrastructure investment exceeding €200 million dedicated to research and technology accumulation, our annual production capacity breached 50,000 Metric Tons in 2018.
Our comprehensive Quality Control (QC) system guarantees absolute batch-to-batch consistency. All raw materials are sourced through a robust global supply chain from world-class petrochemical partners including SINOPEC and Eni. Operating under fully automated production lines, every single batch undergoes rigorous 3-tier testing by our specialized QC team before dispatch, adhering strictly to ISO9001:2008 standards.
Molecular Architecture, Charge Density Tailoring, and Flocculation Dynamics
Polyacrylamide (PAM) is a synthetic, water-soluble polymer prepared by the polymerization of acrylamide monomers. Based on physical form and ionic charge characteristics, PAM is categorized into Anionic Polyacrylamide (APAM), Cationic Polyacrylamide (CPAM), Nonionic Polyacrylamide (NPAM), and Amphoteric/Mannich variants. Among these, Anionic Polyacrylamide represents the most versatile polymer used across heavy industries.
Anionic PAM is produced via the copolymerization of acrylamide with acrylic acid or sodium acrylate, or through the partial hydrolysis of polyacrylamide. The resulting polymer chain contains negatively charged carboxylate groups ($-\text{COO}^-$) alongside non-ionic acrylamide groups ($-\text{CONH}_2$). The negative charges impart unique chemical behaviors in aqueous environments:
Our wholesale APAM ranges from 5 million to 25 million Daltons. Higher molecular weights provide longer polymer chains, enabling ultra-long distance bridging between suspended inorganic particles.
We tailor the degree of hydrolysis (charge density) from 10% to 60%. Low anionicity excels in acidic slurries, while high anionicity is ideal for alkaline mineral suspensions and heavy sludge dewatering.
APAM operates through charge neutralization and polymer bridging. The negative charge extends polymer chains in solution, allowing them to adsorb onto multiple suspended particles simultaneously, forming large, rapidly settling flocs.
| Parameter Grade | Molecular Weight (Million) | Degree of Hydrolysis (%) | Solid Content (%) | Dissolution Time (Mins) | Primary Application |
|---|---|---|---|---|---|
| APAM High MW | 18 - 22 | 20 - 30 | ≥ 88% | ≤ 60 | Municipal Sewage & Sludge Dewatering |
| APAM Ultra-High MW | 22 - 25+ | 25 - 35 | ≥ 88% | ≤ 60 | Enhanced Oil Recovery (EOR) & Profile Control |
| APAM Medium Charge | 12 - 16 | 15 - 25 | ≥ 88% | ≤ 45 | Mineral Processing & Coal Washing |
| APAM Low Charge | 8 - 12 | 10 - 15 | ≥ 88% | ≤ 45 | Paper Dry Strength & Industrial Effluents |
Proven Performance Across Water Treatment, Oil & Gas, Mining, Pulp & Paper, and Agriculture
APAM acts as a high-efficiency primary coagulant aid and sludge dewatering polymer. It clarifies raw water, removes suspended solids (TSS), reduces turbidity, and enhances sedimentation in industrial effluent treatment (tanneries, paper, citric acid, dyeing, and pharmaceuticals).
In tertiary oil recovery, APAM increases water phase viscosity, reducing water mobility and boosting sweep efficiency. It also serves as a key drag reduction additive in hydraulic fracturing, fluid loss control additive, shale inhibitor, and well cementing sealant.
Essential for coal washing, tailings dewatering, and solid-liquid separation. APAM rapidly clarifies tailings water in gold, silver, iron, copper, and alumina operations, enabling fast water recycling and compliance with Zero Liquid Discharge (ZLD) norms.
Functions as a retention and drainage aid, paper dry strength agent, and dispersant. It increases short fiber and filler retention, enhances wet-end paper sheet strength, reduces raw material loss, and clarifies paper mill white water.
Applied as a soil conditioner and anti-erosion agent. APAM improves water infiltration rate, preserves topsoil structure against wind and rain erosion, and enhances moisture retention in dryland farming.
Functions as a warp sizing agent, fabric finishing treatment, and effluent decolorizing flocculant in textiles. In sugar refining, APAM accelerates cane juice clarification, mud settling, and syrup filtration.
Innovations Shaping the Future of Synthetic Water-Soluble Polymers (2025–2030)
Traditional chemical synthesis of acrylamide requires high temperatures and metallic catalysts (e.g., copper-based catalysts), leaving toxic copper residues and higher monomer impurities. Oubo Chemical leverages advanced microbial enzyme technology (nitrile hydratase catalyst). This green chemistry route yields acrylamide with 99.9% conversion purity, zero metallic contamination, and low carbon footprint, setting the benchmark for next-generation polymer production.
Deep-sea drilling, unconventional shale gas fracturing, and extreme mining environments demand polymers that withstand shear degradation, high salinity, and elevated temperatures (up to 120°C). Our R&D engineering team has introduced modified hydrophobic association APAM polymers that build high-viscosity networked structures under harsh saline conditions.
Global procurement teams in North America, Europe, the Middle East, and Southeast Asia face stringent regulatory mandates. Oubo Chemical ensures 100% compliance across international frameworks:
