Description
Anionic polyacrylamide (APAM) is a water-soluble polymer used to support flocculation and solid–liquid separation. It can be evaluated for industrial wastewater clarification, sedimentation and mineral slurry treatment. The appropriate grade and dose depend on the feed and should be confirmed by representative testing.
CAS 9003-05-8 and the repeat-unit formula above are generic PAM references, not verified identifiers for every APAM grade. Check the exact-grade SDS and product documentation.
Our APAM product range includes grades with a stated molecular-weight range of 12–18 million. Available combinations depend on the grade; confirm the molecular-weight measurement basis in the grade-specific TDS.

| Water-insoluble matter | ≤0.3% |
Request the current specification and relevant documentation for the grade and shipment.
Suitability and working dose should be established with representative tests.
Prepare and dose the polymer according to the selected grade and process conditions. Compare suitable grades on representative water or slurry; there is no universal APAM dose.
Keep the package sealed in a cool, dry place away from moisture and direct sunlight. Follow the applicable product TDS, SDS and site safety procedures.
