Direct Factory Wholesale Supply from Qingdao Free Trade Zone | Certified ISO9001:2008 & Bio-Catalytic Standard
Founded in 2011 within the Qingdao Free Trade Zone, Qingdao Oubo Chemical Co., Ltd. (operating under the internationally respected brand O'brien) has risen to become a premier global manufacturer of 99% purity Polyacrylamide (PAM). Our state-of-the-art chemical synthesis infrastructure leverages advanced biological enzymatic methods to achieve unprecedented monomer conversion efficiency and minimal residual acrylamide content.
By enforcing a rigorous 3-tier QC verification protocol across automated production lines, Oubo Chemical supplies high-performance Cationic, Anionic, and Nonionic water-soluble polymers across North America, Europe, Southeast Asia, and the Middle East. With annual production exceeding 50,000 metric tons in 2018 and continuous double-digit expansion, our technical solutions protect local ecosystems while driving operational efficiency for the world's most demanding industrial operators.
Our global supply chain sources premium raw materials from world-class petrochemical leaders including SINOPEC and Eni. Every batch undergoes triple laboratory testing before dispatch, guaranteeing strict adherence to ISO 9001:2008 standards.
Understanding Molecular Weight Distribution, Ionic Charge Densities, and Rheological Mechanics
Unlike traditional chemical synthesis which introduces unwanted trace metallic residues and unreacted monomer impurities, our patented biological enzymatic method yields pure linear acrylamide chains. This technique ensures high purity solid content (99%) with residual monomer (AMD) strictly controlled below 0.05% (500 ppm).
Oubo PAM products feature ultra-high molecular weight profiles ranging from 5 Million to upwards of 25 Million Daltons. High molecular weight polymers extend long molecular bridges across suspended colloidal particles, accelerating particle aggregation and dramatically increasing settling velocities.
We synthesize distinct ionic charge variations: Anionic PAM (carboxylate charged via acrylic acid copolymerization), Cationic PAM (quaternary ammonium sites via DAC/DMAEA monomers, 5-80% mole charge), and Nonionic PAM (homopolymer amide groups) to match any zeta potential requirement.

Expert Guidance on Selecting, Dissolving, and Dosing Polyacrylamide Powder
Anionic Polyacrylamide (APAM) contains negatively charged carboxylate groups and excels in clarifying inorganic mineral suspensions and wastewater with high pH. Cationic Polyacrylamide (CPAM) carries positive quaternary ammonium charges and is specifically engineered for organic sludge dewatering in municipal sewage plants. Nonionic Polyacrylamide (NPAM) carries neutral charges and is ideal for acidic industrial effluent treatments and soil conservation.
PAM dry powder must be slowly sprinkled into a agitated water tank to avoid "fish-eye" agglomerates. Dissolution concentrations are typically between 0.1% and 0.3% (w/v). Use clean tap water with neutral pH (6.5-7.5) at temperatures below 50°C. Mechanical stirring speed should be maintained between 200-400 RPM for 45-60 minutes until fully hydrated.
Acrylamide monomer (AMD) is a known neurotoxin. High-purity PAM requires minimal AMD residual content. Oubo's bio-enzymatic synthesis process guarantees residual acrylamide levels well below 0.05% (500 ppm), satisfying international environmental safety standards for industrial effluent discharge and municipal treatment processing.
In dry powder form, Oubo Polyacrylamide has a shelf life of 24 months when stored in original sealed packaging in a cool, dry, well-ventilated warehouse below 35°C. Once diluted in aqueous solution, the polymer solution should be consumed within 24 to 48 hours to prevent viscosity degradation caused by molecular chain hydrolysis or microbial growth.
