In modern industrial liquid-solid separation, municipal sludge dewatering, and enhanced oil recovery (EOR), selecting high-performance polyelectrolytes with precise molecular weight distribution and charge density is critical. International procurement standards frequently reference benchmark polymers such as SNF FLOERGER 923 SH / 926 SH (cationic and anionic polyacrylamide formulations). As a premier global manufacturer, Qingdao Oubo Chemical Co., Ltd delivers synthetic water-soluble polymers engineered to match and exceed the exact chemical, physical, and rheological performance parameters of the 923 and 926 series.
Polyacrylamide (PAM) (CAS Registry Number 9003-05-8) is a linear synthetic polymer derived from polymerized acrylamide monomers. By synthesizing acrylamide via eco-friendly biological enzymatic catalytic processes, Oubo Chemical produces polyacrylamide powders characterized by ultra-low monomer residual content (<0.05%), superior structural stability, high molecular weights (ranging from 6 million to 22 million Daltons), and customizable ionic charges (Cationic CPAM, Anionic APAM, and Nonionic NPAM).
| Technical Parameter | Global Industry Benchmark (923 / 926 Grade) | Oubo Chemical Equivalent Grade | Operational Benefit |
|---|---|---|---|
| Ionic Type & Charge Density | Low-to-Medium Cationic / Anionic (10% - 40% mol) | Customizable Cationic / Anionic (10% - 80% mol) | Exact Charge Matching Optimizes zeta potential neutralization |
| Molecular Weight (MW) | 8.0 - 15.0 Million Daltons | 8.0 - 18.0 Million Daltons | Enhanced bridging flocculation & shear resistance |
| Dissolution Speed | 45 - 60 minutes | 30 - 45 minutes (Micro-Granular) | Saves dissolution energy & eliminates fisheyes |
| Residual Monomer (AMD) | ≤ 0.05% (500 ppm) | ≤ 0.025% (250 ppm Ultra-Pure) | Meets strict drinking water & environmental standards |
| Apparent Viscosity (0.1% Sol) | 300 - 800 mPa.s | 350 - 950 mPa.s | Lower dosage required per dry ton of solids |
| Form & Physical Appearance | White Free-Flowing Granular Powder | White Micro-Granular Solid Powder | Dust-free, non-hygroscopic handling |
Global environmental regulatory frameworks (including the EU Water Framework Directive and US EPA Effluent Guidelines) are forcing chemical processing, textile, and mining sectors to adopt ZLD practices. This shifts demand toward polyacrylamide grades equal to 923/926 that deliver rapid solid-liquid separation and higher cake dryness in centrifugal and belt filter dewatering.
Procurement directors and wastewater engineers are increasingly shifting away from single-source chemical brands. Purchasing high-purity equivalent polymers directly from Tier-1 Chinese manufacturers allows enterprises to reduce raw material operational expenses by 18% to 35% without sacrificing flocculation kinetics or equipment uptime.
Traditional chemical catalytic synthesis of acrylamide leaves traces of residual monomer and copper ions. Oubo Chemical utilizes advanced bio-catalytic enzymatic technology, producing high molecular weight PAM with clean polymer chain structures, zero metallic contamination, and minimal toxicity for sensitive water treatment and sugar refining.

As an advanced organic flocculating agent, Oubo PAM is widely used in industrial solid-liquid separation processes including primary sedimentation, clarification, effluent concentration, and sludge dewatering. Stringent environmental regulations drive modern municipal sewage treatment and industrial wastewater purification across leather, paper making, citric acid, vegetable protein, dyeing, and pharmaceutical plants.
Utilized as high-efficiency dry strength agents, retention aids, and filter aids. Oubo PAM dramatically improves paper sheet formation, enhances physical mechanical strength, reduces fine fiber loss, recovers white water solids, and acts as a potent flocculant during deinking flotation cycles.
Extensively deployed in oil exploration, profile control, plugging agents, drilling muds, and hydraulic fracturing fluids. Oubo PAM controls fluid loss, stabilizes shale, lubricates drill bits, carries cuttings to the surface, and drives tertiary oil recovery (Enhanced Oil Recovery - EOR).
Essential for solid-liquid separation in coal washing, mineral tailings sedimentation, pipe sealing, and filtration. Our full range of anionic, cationic, and nonionic polymers separates high-density ores including gold, silver, iron, copper, nickel, and alumina slurries.
Specially formulated food-grade anionic flocculants speed up juice clarification and mud flotation during sugarcane and sugar beet juice processing, ensuring crystal-clear syrup extraction and low turbidity.
PAM functions as an economical textile sizing agent, fabric finishing treatment, and rapid color-decolorizing flocculant for complex organic textile mill wastewater effluent streams.
Ideal for organic sludge dewatering in municipal sewage, brewery, paper mill, and tannery wastewater. Charges range from 10% to 80% cationic degree.
High molecular weight (up to 22 Million) polymer for mineral processing, coal washing, steel plant effluent clarification, and sugar juice refining.
Excellent stability in highly acidic or saline wastewater conditions. Widely used in soil conservation, acid leach mining, and textile sizing.
