Description
Polyacrylamide (PAM) is a high molecular weight, water-soluble polymer made from acrylamide monomers. It is widely used as a flocculant, coagulant aid, and thickening agent in various industries. Depending on its ionic character, PAM is available in anionic, cationic, non-ionic, and amphoteric grades. Its ability to enhance solid-liquid separation makes it essential in water treatment, papermaking, oil recovery, and mineral processing.
Specifications
| Grade Type | Description | Typical Molecular Weight (Da) | Ionicity (%) |
|---|---|---|---|
| Anionic PAM | Ideal for municipal/industrial wastewater with suspended solids | 8–20 million | 10–30% |
| Cationic PAM | Best for sludge dewatering and organic-rich wastewater | 5–12 million | 5–60% |
| Non-Ionic PAM | Suitable for low-turbidity and neutral pH systems | 5–12 million | <5% |
| Amphoteric PAM | Contains both cationic and anionic groups, used in complex wastewater | 8–15 million | Customized |
| Emulsion Grade | Liquid form for easy handling and rapid dissolution | 5–12 million | As specified |
| Customized Grade | Ionic strength, particle size, solubility tailored to client requirements | As requested | As requested |
