Polyacrylamide (PAM) is a remarkable synthetic polymer with a vast array of industrial applications, primarily recognized for its exceptional flocculation, thickening, and binding properties. As a leading polyacrylamide manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. provides high-quality PAM to diverse sectors, from water treatment and mining to oil & gas and papermaking. Understanding PAM’s fundamental properties and types is key to leveraging its full potential.

At its core, polyacrylamide is a water-soluble polymer formed from acrylamide monomers. Its chemical formula is (C₃H₅NO)n, and it is commercially available in forms such as white powder, granules, or solutions. Its water solubility and ability to form strong hydrogen bonds contribute to its versatility. The CAS number for polyacrylamide is 9003-05-8.

Key Properties of Polyacrylamide

  • Water Solubility: PAM readily dissolves in water, forming viscous solutions.
  • Flocculation: It effectively aggregates suspended particles, facilitating their removal in water treatment and other separation processes.
  • Thickening Agent: PAM increases the viscosity of liquids, valuable in applications like EOR and drilling fluids.
  • Stability: PAM exhibits good thermal and chemical stability, making it suitable for various industrial conditions.
  • Adaptability: It can be modified to have anionic, cationic, or non-ionic properties, tailoring its performance to specific applications.

Types of Polyacrylamide

The functionality of PAM is largely determined by its ionic character:

Anionic Polyacrylamide (APAM): Characterized by a negative charge, APAM is ideal for treating water with positively charged impurities, such as mineral suspensions in mining or industrial wastewater. We are a premier anionic polyacrylamide powder supplier, offering excellent performance.

Cationic Polyacrylamide (CPAM): Possessing a positive charge, CPAM is effective in treating negatively charged particles, commonly found in organic sludge, municipal sewage, and paper mill wastewater. Its ability to bind to organic matter makes it crucial for sludge dewatering.

Non-ionic Polyacrylamide (NPAM): Lacking a net charge, NPAM is suitable for specific applications where ionic interactions might be undesirable. While less common for general flocculation, it finds use in specialized industrial processes.

Broad Industrial Applications

The versatility of PAM makes it a staple across many industries:

  • Water Treatment: For purification of raw water, treatment of industrial wastewater, and dewatering of sludge.
  • Mining and Mineral Processing: For efficient solid-liquid separation, tailings thickening, and mineral recovery.
  • Oil & Gas: In Enhanced Oil Recovery (EOR), drilling fluids, and friction reduction for hydraulic fracturing.
  • Papermaking: As retention aids, drainage aids, and strength enhancers for paper production.
  • Textile Industry: As sizing agents and thickeners for printing pastes.
