Polyacrylamide (PAM), CAS 9003-05-8, is a water-soluble acrylamide polymer supplied in anionic, cationic, non-ionic and amphoteric grades, as powder (approximately 88-92% active) or emulsion, for water and wastewater treatment, sludge dewatering, mineral processing, papermaking and oilfield use. Drinking-water grades are available with controlled residual acrylamide, and every batch ships with a COA and SDS.
Grades in this range: anionic, cationic, non-ionic and amphoteric, plus drinking-water grades.

Packaging, documentation and compliance
| Item | Supply | Confirm before ordering |
|---|---|---|
| Packaging | 25 kg paper sacks with PE liner; 750 kg / 1000 kg bulk bags on request; emulsion in drums or IBC | Bulk-bag unloading capability, and a frost-free store if you take emulsion |
| Grade | Ionic type, molecular weight band and charge density agreed against a jar test on your own stream | The exact grade code you will re-order – trial and repeat orders must match |
| MOQ and lead time | Confirmed per grade, packing and destination | That the delivery window fits your plant schedule or tender |
| Documentation | Batch COA (solid content, viscosity or molecular weight, residual monomer where applicable) and GHS-format SDS | That measured values – not just “conforms” – appear on the COA |
| Drinking-water grade | Grades with controlled residual acrylamide on request | Residual monomer limit and certification status for potable projects |
| Regulatory | TSCA (US) and REACH (EU) status confirmed on enquiry | Your own registration and tonnage band, since that is what has to match |
Polyacrylamide is bought on performance, not on a single number. Tell us the stream, the solids, the target clarity and the pump you use, and the grade recommendation will follow from that – a cheaper grade that needs a higher dose, or a new make-down pump, is not cheaper.
