Industrial grade Nonionic, Anionic, and Cationic PAM engineered for high-performance thickening, stabilization, and flocculation.
An in-depth chemical and industrial synthesis perspective on high-purity water-soluble polymers.
Polyacrylamide (PAM) is a linear synthetic macromolecule polymer synthesized through the free-radical polymerization of acrylamide monomers ($CH_2=CH-CONH_2$). In modern industrial chemistry, pure polyacrylamide functions as a premier thickener, rheology modifier, suspension stabilizer, and flocculant. Operating across diverse liquid systems, its high molecular weight chain structure (ranging from 3 Million to over 30 Million Daltons) grants exceptional viscosity-building capabilities and particle-bridging dynamics.
The industrial versatility of Polyacrylamide is determined by its ionic charge modification, molecular weight density, and hydrolysis degree. As leading China Polyacrylamide Manufacturers & Factories, chemical synthesis processes have evolved from traditional thermal initiation to advanced biological enzymatic catalysis, yielding polymers with ultra-low residual monomers (< 0.05%) and highly controlled molecular weight distribution curves.
Unmatched supply chain resilience, advanced bio-catalytic technology, and world-class quality assurance.
Oubo utilizes patented biological enzymatic methods for monomer synthesis. This eco-friendly process prevents side-reaction impurities, ensures superior chain linearity, and achieves high purity ideal for sensitive thickener applications.
Operating under ISO9001:2008 certifications, all raw materials are directly procured from global petrochemical leaders like SINOPEC and Eni. Every batch undergoes 3 rigorous quality control tests prior to shipment.
Located in the Free Trade Zone of Qingdao, China, Oubo leverages direct maritime transport routes, ensuring optimized shipping lead times, customized container loading, and seamless international trade logistics.
From charge density (cationic degree 5%-80%, anionic degree 5%-60%) to target molecular weight selection (3M to 26M), our chemical engineers customize PAM solutions for precise customer viscosity targets.

Our technical team works alongside global industrial buyers from pre-sales technical selection and lab jar testing to post-sales field dosing optimization, driving environmental sustainability across global industries.
Understanding ionic types to optimize thickening, stabilizing, and solids-liquid separation efficiency.
Formulated without ionic functional groups on the polymer backbone. Highly effective as a rheology modifier and neutral thickener in acidic liquid environments, mineral leaching processes, and oilfield drilling muds.
Copolymerized with acrylamide and acrylate monomers carrying negative carboxylate charges ($-COO^-$). Delivers extremely high viscosity, rapid water solubility, and superior flocculation for inorganic suspensions, mineral tailings, and paper dry strength.
Copolymerized with cationic monomers (DAC/ADAME/METAC) containing positive quaternary ammonium groups. Crucial for organic sludge dewatering, municipal sewage treatment, and wet-end retention in paper manufacturing.
Pure Polyacrylamide serves as a vital functional chemical across global heavy industries and environmental projects.
Polyacrylamide acts as an indispensable primary coagulant aid and sludge dewatering polymer. It accelerates solid-liquid clarification in settlement tanks, centrifugation, and belt filter presses. Widely specified for wastewater treatment in municipal plants, leather tanneries, paper mills, food processing, citric acid extraction, vegetable protein recovery, dyeing, and pharmaceutical plants.
Functions across wet-end paper engineering as retention agents, drainage aids, and paper strength modifiers:
In tertiary oil recovery (Enhanced Oil Recovery - EOR), pure PAM increases water drive viscosity to improve sweep efficiency in subterranean reservoirs. In drilling operations, it functions as a primary drilling fluid thickener, shale inhibitor, fluid loss control agent, and drill bit lubricant under extreme temperature and shear conditions.
Essential for coal washing, tailings thickeners, and metal extraction centrifuges. Accelerates solid-liquid separation in mineral leaching circuits for Gold, Silver, Iron, Copper, Nickel, and Aluminum ores, promoting clean water recycle streams and tight tailings pond management.
Utilized during sugarcane and sugar beet juice clarification and syrup flotation processes. Pure, food-grade compliant PAM flocculates plant impurities quickly without leaving toxic residues, improving sucrose purity and crystallization yield.
Functions as a reliable textile sizing agent, fabric finishing thickener, and anti-static processing chemical. In wastewater treatment, CPAM and APAM treat complex dye effluent, removing color, chemical oxygen demand (COD), and suspended solids.
