Oubo Chemical Co., Ltd was established in 2011 and is strategically located within the Free Trade Zone of Qingdao, China. Operating under an uncompromising Quality Control (QC) framework, Oubo has maintained a consistent annual business growth rate of over 10% for more than a decade. We are deeply committed to chemical quality, operational safety, and minimizing environmental impacts throughout our synthetic polymer production cycles.
Oubo specializes in the synthesis of Anionic Polyacrylamide (APAM), Cationic Polyacrylamide (CPAM), and Nonionic Polyacrylamide (NPAM). Utilizing state-of-the-art enzymatic polymer synthesis lines and automated quality inspection rigs, our manufacturing infrastructure surpassed an annual capacity of 50,000 Metric Tons in 2018. Our rigorous quality management system is fully certified under ISO 9001:2008 and compliant with global environmental standards.
By implementing cutting-edge bio-acrylamide monomer production techniques, Oubo reduces carbon intensity while guaranteeing ultra-high molecular weight retention and exceptionally low residual monomer levels (<0.05%), matching standard chemical benchmarks such as SNF Flopam AN 923 and AN 926.
Industrial procurement managers frequently seek drop-in replacements for standard international anionic flocculants such as Flopam AN 923 and Flopam AN 926. Oubo Chemical’s custom polymer formulations provide exact functional and physical equivalence:

Polyacrylamide (PAM) (CAS Registry Number 9003-05-8) is a synthetic, water-soluble polymer produced via the free-radical polymerization of acrylamide monomers. Based on functional charge modifications, PAM is categorized into Anionic Polyacrylamide (APAM), Cationic Polyacrylamide (CPAM), and Nonionic Polyacrylamide (NPAM). The high-molecular weight anionic polymers—such as the AN 923 and AN 926 equivalents—contain carboxylate functional groups alongside amide groups. These molecular structures act as powerful flocculants, coagulants, and rheology modifiers by bridging suspended charged solids in aqueous environments, forming heavy flocs that settle rapidly.
Engineered polyacrylamide products fulfilling rigorous global compliance, process optimization, and environmental remediation standards.
In municipal sewage and industrial effluent purification, our AN 923/926 equivalent APAM rapidly destabilizes colloidal suspensions. It is extensively applied in primary clarification, dissolved air flotation (DAF), and secondary sludge dewatering equipment, including belt filter presses, decanter centrifuges, and screw presses, dramatically reducing chemical sludge volume and disposal fees.
Our APAM acts as an advanced dry strength agent, retention aid, and filtration accelerator. By balancing wet-end chemistry and scavenging anionic trash, it enhances short-fiber filler retention, minimizes fiber loss into white water, and accelerates paper machine dewatering speeds while elevating tensile and bursting strength.
Polyacrylamide plays a critical role in Enhanced Oil Recovery (EOR), profile control, and drilling mud modification. High molecular weight APAM increases the viscosity of injected water, improving sweep efficiency in reservoir porous media. It serves as a friction reducer in hydraulic fracturing and stabilizes shale formations against fluid loss.
Used widely across coal washing, copper extraction, alumina red mud settling, gold, silver, and iron recovery. AN 926 equivalent APAM facilitates ultra-fast solid-liquid separation in thickeners and tailing ponds, enabling closed-loop circuit water recycling and compliant tailing dry-stacking.
Specifically purified food-grade APAM polymers accelerate sugarcane juice clarification and syrup flotation. The polymer effectively binds organic impurities and insoluble plant matter, producing clear juice while optimizing evaporation efficiency and crystal yield.
Functions as a warp sizing additive for smoother fabric weaving and as a potent de-colorization flocculant in textile dye effluent. It aggregates fine dye particles and heavy metals, aiding seamless secondary biological or chemical oxidation processes.
Specific operational mechanics of Polyacrylamide applications across key industrial sectors.
1. Paper Retention Agent: Significantly improves the retention rate of short fibers and inorganic fillers (calcium carbonate, kaolin clay), enhancing paper opacity while dropping raw material costs.
2. Anionic Garbage Scavenger: Neutralizes interfering organic anionic charge build-up in wet-end pulp circuits, maintaining chemical additive performance equilibrium.
3. Dry Strength Agent: Amide groups form covalent and hydrogen bonds with fiber hydroxyl groups across the entire pH range, substantially elevating tensile and burst indices.
4. Fiber Dispersant: Promotes uniform fiber distribution in thin stock sheets, perfecting paper visual formation, softness, and structural toughness.
Enhanced Oil Recovery (EOR): High-MW polymers increase water phase viscosity to lower mobility ratios, driving trapped crude from low-permeability rock pores.
Drilling Fluid Additive: Imparts high shear-thinning rheology, lubricates drill strings, cools bits, prevents borehole shale swelling, and lifts drill cuttings to the surface.
Coal Washing & Tailings Dewatering: Rapidly clarifies slurry circuit water. Agglomerates sub-micron fine clay particles into massive flocs, allowing rapid vacuum filter dewatering.
