In-depth breakdown of material safety parameters, chemical composition, physical properties, and handling safety.
Anionic Polyacrylamide (APAM) is a linear water-soluble high polymer synthesized via copolymerization of acrylamide and acrylic acid monomer units, neutralized with sodium hydroxide. The degree of anionicity (hydrolysis level) varies based on application requirements, ranging from low (5%) to high (80%) negative charge density.

Patented biological enzymatic polymerization technique ensuring superior polymer stability and environmental safety.
Our bio-catalytic enzyme method produces high-purity acrylamide monomers without heavy metal contamination (such as copper catalyst residues), maintaining free monomer content under 0.05% for demanding MSDS standards.
Biological polymerization yields ultra-high molecular weight chains (up to 25 Million Daltons) with narrow molecular weight distribution, maximizing bridging flocculation efficiency in heavy solids separation.
Superior polymer chain integrity resists mechanical degradation during high-shear agitation, making Oubo APAM exceptionally stable in high-salinity oilfield flooding and deep mining slurry decantation.
Oubo Anionic Polyacrylamide provides high-performance performance across diverse global sectors.
As a high-efficiency primary flocculant and coagulation aid, Anionic Polyacrylamide neutrallizes positively charged particulate suspensions, forming robust micro-flocs that settle rapidly. It is extensively applied in primary sedimentation, secondary clarification, and centrifuge or belt filter press sludge dewatering across municipal sewage plants, chemical facilities, and metal plating effluents.
In the wet-end section of paper manufacturing, APAM functions as a high-performance dry strength agent, retention aid, and drainage accelerator. By creating ionic bonds between pulp fibers and inorganic fillers (calcium carbonate, titanium dioxide), it drastically cuts fiber loss while improving sheet uniformity and burst strength.
In tertiary oil recovery, high molecular weight APAM acts as a mobility control agent, increasing water phase viscosity to optimize sweep efficiency in subterranean reservoirs. Furthermore, in drilling fluid engineering, APAM serves as a shale inhibitor, fluid loss reducer, and lubricant to protect drill bits under high-temperature and high-pressure (HTHP) conditions.
Mineral processing generates vast volumes of mineral slurry. Oubo APAM accelerates counter-current decantation (CCD), thickener sedimentation, and tailings filtration across coal washing plants, gold cyanidation, copper solvent extraction, and iron ore processing circuits, ensuring rapid recycling of process water.
