For procurement managers and R&D scientists in the chemical industry, understanding product specifications is paramount to making informed purchasing decisions. Polyacrylamide (PAM) is no exception. This versatile polymer is used in a myriad of applications, from water treatment to papermaking and mining. When you decide to buy Polyacrylamide, a thorough grasp of its key specifications will ensure you select the most suitable grade for your needs. NINGBO INNO PHARMCHEM CO.,LTD. is a leading manufacturer and supplier of high-quality PAM and is committed to educating its clients.

Key Specifications of Polyacrylamide (PAM)

When sourcing PAM, you will encounter several critical parameters that define its performance:

  1. Type (Anionic, Cationic, Non-ionic): This refers to the charge of the polymer chain. The choice depends heavily on the application and the nature of the materials being treated. For example, in wastewater treatment, the charge of suspended particles dictates whether APAM or CPAM is more effective.
  2. Molecular Weight: PAM is available in a wide range of molecular weights, from a few million to tens of millions g/mol. Higher molecular weights generally lead to more effective bridging and stronger floc formation, which is beneficial for applications like sludge dewatering or sedimentation. However, very high molecular weights can also increase solution viscosity, making handling more difficult.
  3. Ionic Charge / Degree of Hydrolysis (for APAM): For Anionic Polyacrylamide (APAM), the degree of hydrolysis (or ionic charge) indicates the percentage of ester groups that have been converted into carboxylate groups. This parameter significantly influences its interaction with positively charged particles. A common range is 20-30%.
  4. Ion Degree (for CPAM): For Cationic Polyacrylamide (CPAM), the ion degree represents the percentage of quaternary ammonium groups. This determines its cationic strength and its effectiveness in flocculating negatively charged materials like organic sludge. Typical ion degrees range from 10% to 50%.
  5. Solid Content: This indicates the percentage of active polymer in the product. Higher solid content means more active polymer per unit mass, which can be more economical.
  6. Insoluble Matter: The percentage of material that does not dissolve in water. Lower insoluble matter is desirable for cleaner performance.
  7. Residual Monomer: Acrylamide monomer is the building block of PAM. Residual monomer content is a critical safety and environmental parameter. Reputable manufacturers, like NINGBO INNO PHARMCHEM CO.,LTD., ensure very low residual monomer levels (e.g., ≤0.05%).
  8. Appearance: PAM is typically supplied as a white granular powder or bead.
