Qingdao Oubo Chemical Co, Ltd is highly committed to quality, service excellence, and pays rigorous attention to environmental sustainability during polymer synthesis and field applications.
Oubo specializes in supplying high-performance Cationic Polyacrylamide (CPAM), Anionic Polyacrylamide (APAM), and Nonionic Polyacrylamide (NPAM). Equipped with advanced automated synthesis lines and an elite chemical engineering staff, we ensure every order meets exact molecular parameters. Our annual polyacrylamide production capacity surpassed 50,000 Metric Tons in 2018, backed by an ISO9001:2008 quality management certification. We proudly stand behind every batch of chemical flocculants we supply worldwide.
Oubo Chemical maintains an unyielding commitment to green synthesis. By integrating patented biological enzymatic acrylamide production methods, we achieve ultra-low residual monomer content (<500 ppm), safeguarding aquatic ecosystems while delivering peak flocculation efficiency to global industrial clients.
Polyacrylamide (PAM) is a linear, water-soluble synthetic resin prepared through the radical polymerization of acrylamide monomers. Cationic Polyacrylamide (CPAM) is synthesized by copolymerizing acrylamide with positively charged cationic monomers—most notably DAC (Acryloyloxyethyltrimethyl ammonium chloride) or DMC (Methacryloyloxyethyltrimethyl ammonium chloride)—or through post-polymerization chemical modification (Mannich reaction).
Ranging from 6 Million to over 15 Million Daltons. Higher molecular weights maximize inter-particle bridging, essential for high-shear decanter centrifuges and belt filter presses.
Engineered from 10% to 80% mole fraction. Low charge CPAM targets inorganic-rich sludges; medium-to-high charge CPAM effectively neutralizes organic-heavy municipal and biological sludges.
Oubo leverages advanced biological enzymatic monomer synthesis. This proprietary process prevents unwanted branching, producing hyper-linear polymer chains with exceptional shear resistance.
Oubo Chemical PAM products provide reliable, tailored solutions across a wide spectrum of industrial and municipal activities worldwide:
As a primary flocculating agent, CPAM is deployed in solid-liquid separation processes including sedimentation, clarification, thickening, and sludge dewatering. Increasingly stringent worldwide environmental regulations drive higher performance standards in wastewater handling.
For municipal sewage, CPAM destabilizes biological sludge flocs. It is also widely used in specialized industrial effluents including leather processing, paper production, citric acid synthesis, vegetable protein extraction, textile dyeing, pharmaceuticals, and incense manufacturing.
In the paper industry, polyacrylamide serves as a retention agent, drainage aid, dry strength agent, and filter aid. It drastically enhances paper sheet quality, boosts physical tensile/burst strength, and reduces fiber loss during wet-end operations while clarifying white water and flocculating ink waste during deinking.
Polyacrylamide is vital in oil production, drilling fluid rheology, profile control, plugging agents, and hydraulic fracturing fluids. It drastically reduces fluid loss, inhibits shale swelling, cools and lubricates drill bits, and carries drill cuttings efficiently to the surface.
Key application sub-sectors include: Enhanced Oil Recovery (EOR), Hydraulic Fracturing Fluid Additives, Drilling Mud Friction Reducers, and Oil Sands Tailings Flocculants.
Polyacrylamide accelerates solid-liquid separation in mineral processing, slurry thickening, and wastewater clarification. Oubo supplies nonionic, anionic, and cationic polymers engineered for specific pH levels and ore charge profiles across Coal Washing, Tailings Dewatering, Filtration/Centrifugation, and Precious Metal Extractive Metallurgy (Gold, Silver, Copper, Iron, Nickel).
In sugar manufacturing, polyacrylamide acts as a high-clarity settling agent in sugarcane juice clarification and flotation syrup purification, producing sparkling liquor with minimal sugar loss.
PAM is applied as an efficient textile sizing agent, fabric finishing agent, and anti-static protective layer. It simultaneously serves as the primary decolorizing flocculant for textile dyeing wastewater.
Procurement officers and chemical engineers worldwide are shifting focus from simple unit-price evaluation to Total Cost of Ownership (TCO) strategies. The key performance metrics driving modern bulk procurement include:
Global environmental directives demand ultra-low residual monomers and biodegradable synthetic chains. Oubo's bio-acrylamide technology meets EU REACH standards and rigorous North American aquatic toxicity limits.
Sludge disposal costs correlate directly to water mass. Selecting custom-charge CPAM elevates dewatered sludge cake dryness by 3%–8%, saving municipal operators millions in transport and incineration expenses.
Fast-dissolving dry powders (<45–60 minutes dissolution rate) eliminate polymer fish-eyes, prevent chemical pump clogging, and reduce mixing energy consumption across automated dosing units.
Qingdao Oubo Chemical operates at the intersection of chemical synthesis innovation and raw material integration. Located in the Free Trade Zone of Qingdao, our infrastructure ensures unmatched logistics access and supply security.
All key precursor chemicals are procured directly through strategic long-term agreements with global petrochemical giants including SINOPEC and Eni, insulating our clients from international market price volatility.
Our production lines are completely automated, featuring continuous online monitoring. Every production batch undergoes three distinct laboratory quality tests before final release by our internal QC team.
Our dedicated chemical engineering team participates directly across pre-sales selection, sample laboratory bench testing, site jar-testing, and post-sales dosing optimization.

Oubo Chemical provides flexible, highly durable packaging options engineered to prevent moisture degradation and ensure long shelf life during transit:
Neutral, unbranded 25kg multi-wall kraft paper bags with inner PE lining for OEM distributors.
Standard O'Brien brand 25kg moisture-proof woven bags built for international shipping.
Custom multi-language printed bags or 750kg/800kg jumbo super-sacks for automated dosing plants.
Fumigated ISPM-15 compliant pallets wrapped in heavy-duty shrink film for maximum stack stability.
Selection depends primarily on the volatile suspended solids (VSS) ratio and organic content of the sludge. High-organic biological sludges (e.g., municipal activated sludge, food processing effluent) require higher cationic charge density (40%–60%). Inorganic-heavy industrial sludges respond best to low-to-medium charge polymers (10%–30%). Oubo Chemical offers lab-scale jar testing to identify the exact optimum grade.
Prepare a solution at 0.1% to 0.3% concentration using clean tap water (pH 6–8, temperature 20°C–35°C). Slowly sprinkle dry powder into the vortex created by low-shear mechanical stirring (200–400 RPM). Maintain agitation for 45–60 minutes until completely dissolved. Avoid high-shear pumps (such as high-speed centrifugal pumps) which break long polymer chains.
Dry polyacrylamide powder has a shelf life of 24 months when stored in unopened original packaging in a cool, dry, well-ventilated area away from direct sunlight and humidity. Aqueous polymer solutions should be consumed within 24–48 hours for optimal flocculating power.
Our enzymatic bio-synthesis yields higher molecular purity, higher linear chain consistency, and ultra-low residual monomer content (<500 ppm). This ensures higher shear resistance during high-speed centrifuge dewatering and reduced environmental toxicity in discharge water.
