Explore our premium grade chemical solutions engineered for maximum flocculation efficiency, rapid sedimentation, and tailored molecular weights.
Anionic Polyacrylamide (APAM) powder represents a cornerstone of modern industrial separation technology. As global environmental regulations tighten and resource extraction requires higher efficiency, high-grade polymers serve as essential catalysts for industrial growth.
Polyacrylamide (PAM) is a synthetic, water-soluble linear polymer formed from acrylamide subunits. Anionic Polyacrylamide (APAM) is produced by copolymerizing acrylamide with acrylic acid or sodium acrylate, imparting negative electrical charges along the polymer backbone. This molecular structure enables exceptional charge neutralization and interparticle bridging during solid-liquid separation processes.
As a premier manufacturer based in the Free Trade Zone of Qingdao, China, Qingdao Oubo Chemical Co., Ltd. (established in 2011) leverages advanced biological enzymatic methods for monomer synthesis. This proprietary process yields higher molecular weights, ultra-low monomer residues, and superior thermal stability compared to conventional chemical synthesis techniques.
Engineered for precise performance customization. Match charge density and molecular weight to your specific industrial slurry characteristics.

Our O'brien brand polyacrylamide products are tailored for complex environmental and chemical process demands globally.
APAM acts as a high-efficiency flocculant in solid-liquid separation. It accelerates particle sedimentation in primary clarifiers, reduces turbidity, and enhances dewatering in dissolved air flotation (DAF) systems.
Polyacrylamide plays a critical role in secondary and tertiary oil recovery. By increasing sweep efficiency in reservoir flooding, APAM significantly boosts crude oil production.
Mining operations generate vast amounts of slurry. APAM accelerates settling rates in thickeners and clarification units across various ore processing circuits.
APAM acts as an essential wet-end chemical additive, enhancing paper sheet uniformity, tensile strength, and machine retention efficiency.
Meeting international industrial requirements through robust supply chain logistics, verified quality control, and competitive total cost of ownership (TCO).
Unlike traditional chemical synthesis, our patented biological enzymatic process produces acrylamide monomer at room temperature. This minimizes toxic impurities (such as unreacted acrylamide monomer ≤ 0.05%) and delivers extremely long polymer chains for superior performance.
Strategic purchasing of raw chemical materials directly from global energy leaders like SINOPEC and Eni guarantees pristine purity. Coupled with automated manufacturing lines, every batch exhibits batch-to-batch consistency.
In accordance with ISO 9001:2008 standards, every consignment undergoes triple-point analytical testing prior to shipment: raw material verification, real-time polymerization monitoring, and final product performance testing (viscosity, insolubles, charge density).
Customized packaging options designed to preserve powder integrity against moisture degradation during ocean freight and multi-stage transit.
Neutral 25kg PE/PP bags suitable for distributor private labeling.
Standard 25kg multi-wall kraft paper bag with inner plastic liner.
