Polyacrylamide (PAM) is a synthetic resin prepared by polymerizing acrylamide. It is a white, solid, water-soluble polymer of acrylamide, mostly used as a flocculant, coagulant, and filtration aid in a whole range of applications determined by its physical form and ionic type (nonionic, anionic, cationic, and Mannich).
It is utilized in secondary oil recovery, as a thickening agent, a flocculant, and an absorbent. Moreover, polyacrylamide is also employed to separate macromolecules of different molecular weights across diverse industrial processes.
Positively charged; ideal for sludge dewatering and municipal wastewater treatment.
Negatively charged; widely used in mining, papermaking, and oil field applications.
No ionic charge; effective in acidic environments and textile processing.
Modified cationic; enhanced performance in complex industrial wastewater scenarios.
Our comprehensive PAM product line delivers perfect solutions across water treatment, oil & gas, mining, agriculture, paper, textiles, and more. Every batch is triple-tested before delivery.

Oubo PAM products provide perfect solutions across a broad spectrum of industrial applications — from municipal water treatment to oilfield operations and mining.
As a flocculating agent, PAM is mainly used in industrial solid-liquid separation processes, including settlement, clarification, concentration, and sludge dewatering. Polyacrylamide plays an important role in municipal sewage treatment and industrial wastewater treatment. Increasingly stringent regulations continue to promote the development of the water treatment industry.
For municipal sewage treatment, PAM is also widely used in leather, papermaking, citric acid, vegetable protein extraction, dyeing, pharmaceutical, and fragrance industries.
In the paper industry, PAM can be used as dry strength agents, retention agents, and filter aids. They greatly improve paper quality, enhance the physical strength of paper, reduce fiber loss, and can be used in white water treatment. In the deinking process, PAM plays a significant flocculation role.
Paper Retention Agent: Significantly improves the retention rate of short fiber filler and filling material, improving dewatering rate and reducing raw material consumption costs.
Anionic Garbage Capture Agent: Interacts with anionic garbage and fillers to neutralize anionic charge, balancing the wet part and increasing retention rates of fillers, fibers, and chemical accessories.
Paper Strength Agent: Fully ionized across the entire pH range; directly adsorbed onto pulp fiber through ionic linkage and covalent bonds to improve binding strength between fibers.
Paper Dispersant Agent: Promotes fiber dispersion and improves paper appearance; enhances pulp evenness, paper softness, and toughness.
From oilfield operations to sugar refining and textile manufacturing, Oubo PAM delivers measurable performance improvements across every sector.
Polyacrylamide is widely used in oil exploration, profile control, plugging agents, drilling fluids, and fracturing fluid additives. It plays a critical role in Enhanced Oil Recovery (EOR), reducing drilling fluid loss, and stabilizing shale formations.
Polyacrylamide is widely used in mining — not only for separating minerals and ore, but also as a flocculant for wastewater treatment and sealing mining pipes. Our full range covers non-ionic, anionic, and cationic products at varying molecular weights.
Polyacrylamide can be used in the clarification and flotation stages of the sugar-making process, improving the efficiency of juice purification and reducing impurities in final sugar products.
PAM drilling fluid additives for drop in fluid loss, shale inhibition, dilution, plugging, cooling, and lubricating drill bits and strings.
Effective solid-liquid separation by filtration and centrifugation for gold, silver, iron, nickel, and copper mineral processing.
Full range polymer products — non-ionic, anionic, and cationic — at varying molecular weights to suit the varied needs of the mining industry.
PAM can be used as a textile sizing agent, finishing agent, and fabric treatment agent. It improves the strength and smoothness of textile fibers during processing, reduces breakage, and enhances the overall quality of finished fabric products.
Polyacrylamide could be used in clarification and flotation of the sugar-making process, helping to purify juice, remove impurities, and increase the efficiency of sugar crystallization in both cane and beet sugar production.
