Explore high-performance Anionic Polyacrylamide (APAM), Partially Hydrolyzed Polyacrylamide (PHPA), Cationic, and Nonionic Formulations engineered for maximum industrial throughput.
Polyacrylamide (PAM) represents a versatile class of synthetic water-soluble polymers synthesized from acrylamide monomers through free-radical polymerization. In industrial applications, particularly within the petroleum extraction, mining, and liquid-solid separation sectors, Anionic Polyacrylamide (APAM) and Partially Hydrolyzed Polyacrylamide (PHPA) dominate due to their unique molecular chain dynamics, high molecular weight, and charge density customization capabilities.
The molecular backbone of APAM is formed by copolymerizing acrylamide with acrylic acid or sodium acrylate, resulting in negative carboxylate charges along the linear hydrocarbon chain ($[-CH_2-CH(CONH_2)-]_x[-CH_2-CH(COO^-Na^+)-]_y$). Alternatively, PHPA is manufactured through the partial alkaline hydrolysis of pure polyacrylamide, converting a controlled ratio of amide groups ($-CONH_2$) into carboxylic groups ($-COO^-$). This hydrolysis ratio—typically calibrated between 5% and 40%—directly dictates the polymer's charge density, conformation in aqueous media, and affinity toward mineral particles or formation clays.
Ranging from 5 Million to upwards of 25 Million Daltons. Extended molecular lengths provide superior inter-particle bridging, creating robust flocs rapidly in high-turbidity systems.
Precision-tuned anionic charge (5%–40%) allows exact electrostatic matching to suspended solids, clay platelets, and reservoir mineral surfaces.
Utilizing microbiological enzymatic catalysts for acrylamide monomer synthesis yields ultra-pure monomers free of copper or chemical residue, preventing structural chain degradation.
At Qingdao Oubo Chemical Co., Ltd (established in 2011 within the Qingdao Free Trade Zone), our production methodology leverages patented biological enzymatic processes. Traditional chemical synthesis methods utilizing copper catalysts often leave trace metal contaminants that act as free-radical initiators, leading to polymer degradation over time. Our bio-enzymatic synthesis yields hyper-pure acrylamide monomers, ensuring exceptionally long polymer chain lengths, enhanced thermal stability, and prolonged shear resistance in harsh field conditions.
By preventing chemical thermal degradation during polymerization, Oubo's PHPA maintains an ultra-high molecular weight (>22 Million Daltons) with tight molecular weight distribution curves. This translates into 30% lower dosing requirements in Enhanced Oil Recovery (EOR) and oilfield drilling mud formulations compared to standard chemically-catalysed alternatives.
Comprehensive technical coverage across water treatment, hydrocarbon extraction, mining, and industrial process engineering.
In drilling fluids, PHPA serves as a fundamental shale inhibitor, viscosity builder, friction reducer, and fluid loss control agent. Its high-affinity anionic carboxylic groups adsorb onto positive edge charges of clay particles, encapsulating shale cuttings to prevent swelling, bit balling, and wellbore collapse.
APAM acts as an indispensable primary coagulant aid and flocculant for inorganic suspended solids. In municipal sewage plants and heavy industrial effluent treatment (petrochemical, tannery, plating, paper), APAM accelerates charge neutralization and bridges colloidal particles into macro-flocs.
Mineral processing circuits require efficient liquid-solid separation to recover valuable metals and recycle process water. Oubo APAM formulations are specialized for mineral slurries across gold, copper, iron, alumina (Bayer process red mud), and coal washing operations.
In modern high-speed paper manufacturing, APAM functions as a crucial retention aid, drainage promoter, dry strength agent, and anionic trash catcher. It bridges fine pulp fibers and fillers (titanium dioxide, calcium carbonate) to the sheet structure.

Purchasing bulk polyacrylamide globally involves evaluating Total Cost of Ownership (TCO), active polymer content, shelf-life integrity, and logistics security. Situated in the Qingdao Free Trade Zone, Oubo Chemical profits from immediate deep-water port connectivity, allowing rapid containerized ocean freight movement to North America, South America, the Middle East, Southeast Asia, and Europe.
Polyacrylamide powders are highly hygroscopic. Store bags in a cool, dry, ventilated warehouse at temperatures between 5°C and 35°C. Avoid exposing opened bags to ambient humidity. When preparing stock solutions, slowly sprinkle powder into the vortex of agitated water (turbulent mixing at 200-400 RPM) to prevent the formation of undissolved agglomerates ("fish-eyes").
