Non-Ionic Polyacrylamide NPAM Powder, CAS 9003-05-8, Oilfield and Water Treatment Flocculant
Buyer-facing sourcing candidate for non-ionic polyacrylamide NPAM powder listed as CAS 9003-05-8 with formula (C3H5NO)n. The listing positions the material for oilfield additives, emulsifier/stabilizer systems, industrial flocculation, and circulating water treatment. Before RFQ or sampling, buyers should verify polymer type, molecular weight range, hydrolysis or ionic degree, residual acrylamide monomer, moisture, insolubles, viscosity, and whether the quoted 99% specification refers to active polymer, dry basis, or another internal standard.

CAS No.: 9003-05-8, to be confirmed against product COA and SDS
Chemical formula listed: (C3H5NO)n
Polymer type: non-ionic polyacrylamide requested; confirm NPAM versus APAM or CPAM
Appearance: white powder or white crystalline powder as listed; confirm actual particle form and granule size
Purity or active content: listed as 99%; confirm test basis and method
Water solubility: listed as soluble in water; request dissolution time and insoluble matter limits
Density at 20 °C: listed as 1.302 g/cm³; confirm whether this is bulk density or true density
Shelf life: listed as 2 years; confirm storage condition assumptions on supplier documents
Key missing checks for procurement: molecular weight range, viscosity, degree of hydrolysis, ionic charge, residual acrylamide monomer, moisture, ash, pH, insoluble content, and particle size distribution

Package and route
Packing notes
Listed transport package: 25 kg; request bag type, liner details, palletization, and container loading quantity
Listing also shows package size 58 cm x 58 cm x 90 cm and gross weight 220 kg, which appears inconsistent with a 25 kg package and should be clarified
Supplier states regular and customized packing may be available
For export RFQ, ask whether neutral packaging, OEM labeling, batch coding, and pallet stretch wrapping are available
For samples or small orders, listing suggests express or air transport; for mass orders, sea container transport is suggested
Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Oilfield additive formulation where non-ionic polymer profile is specified by the buyer
Industrial wastewater flocculation procurement after jar-test validation
Circulating water treatment chemical supply programs
Sludge dewatering chemical trials
Mining tailings or process-water clarification trials
Paper and textile wastewater treatment chemical sourcing
How we compare
Sourcing options
Request NPAM powder sample with full COA and SDS for lab screening
Compare non-ionic, anionic, and cationic PAM grades based on jar-test or field-test performance
Source 25 kg bags for trial order before container-scale procurement
Ask for customized packaging, buyer label, or mixed-container shipment if documentation and labeling are compliant
Use third-party inspection for batch identity, packaging condition, and key specification checks before shipment
Human review
Compliance notes
Request current SDS, COA, TDS, product specification sheet, packing list template, commercial invoice template, and certificate of origin if required
Confirm exact CAS, HS code, polymer classification, and export declaration description before shipment
Listed HS code is 3402410000, which may not match all destination customs interpretations for polyacrylamide; importer should verify locally
Check residual acrylamide monomer limits against buyer country, end-use, and customer specifications
Do not rely on the listing alone for regulatory status, food-contact suitability, drinking-water use, oilfield approval, or wastewater discharge compliance
DG status should be confirmed from the supplier SDS and freight forwarder; polymer powders may require dust and packaging review even when not shipped as regulated dangerous goods
Page text contains a material-name inconsistency referencing etidronic acid while listing CAS 9003-05-8 and formula (C3H5NO)n; this must be resolved before procurement
