Anionic Polyacrylamide Powder for Oily Wastewater and Sludge Dewatering
Buyer-facing sourcing candidate for white powder anionic polyacrylamide used as a water-treatment flocculant in oily wastewater, sludge dewatering, raw water clarification, mining, and oilfield-related applications. Key checks before RFQ should focus on CAS confirmation, anionic charge, molecular weight range, hydrolysis degree, solid content, residual acrylamide, insolubles, packing format, COA/SDS readiness, and export classification.
Quick buying facts
Identify the grade, package, and import market before comparing suppliers.
Use this page to check the product identity, common specification points, document scope, package notes, and destination-market questions before sending a China sourcing request.
CAS number: supplier page lists 9005-05-8; buyer should verify against COA/SDS and intended polymer identity, as polyacrylamide is commonly referenced under CAS 9003-05-8Water treatment polymer / anionic polyacrylamide flocculantCandidate - document verification required
Polymer type: anionic polyacrylamide / partially hydrolyzed polyacrylamide, to be confirmed by grade
CAS number: supplier page lists 9005-05-8; buyer should verify against COA/SDS and intended polymer identity, as polyacrylamide is commonly referenced under CAS 9003-05-8
Solid content: minimum 90% as stated on source page
Ionicity / anionic degree: required for grade selection; not fully stated in source data
Molecular weight: required for RFQ; not stated in source data
Hydrolysis degree: required for PHPA/oilfield or wastewater grade selection; not stated in source data
Residual acrylamide monomer: request maximum ppm specification and test method
Insoluble matter: request maximum value
Dissolution time / particle size: request supplier specification if dosing equipment compatibility is relevant
pH range or solution pH: request test basis and concentration used
Shelf life: source page states 2 years when properly stored; confirm on COA/SDS and packaging label

Chemical importers sourcing polymer flocculants in bulk bags or 25 kg bags
Before matching
Documents to check
CAS number, grade, assay, and impurity profile
SDS, COA, TDS, HS code, and transport classification
Destination-market import documents before supplier matching
Package and route
Packing notes
Source page states 25 kg kraft paper bag and 25 kg PE bag options
Confirm whether bags include inner PE liner and moisture-resistant sealing
For export orders, request palletization details, net/gross weight, container loading quantity, and fumigation-free pallet availability
Ask whether private label, neutral packing, or buyer-specified marks are available
Confirm batch number, production date, expiry date, and grade code appear on each bag
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
Oily wastewater flocculation and clarification
Sludge thickening and dewatering
Raw water clarification
Industrial wastewater treatment
Mining tailings thickening and water recovery
Oilfield drilling or EOR-related polymer applications, subject to grade confirmation
How we compare
Sourcing options
Request anionic PAM grade with defined molecular weight and charge density
Request PHPA grade for oilfield-related use if hydrolysis degree is critical
Request wastewater-treatment grade with residual acrylamide specification
Request sample and COA for lab jar-test comparison before bulk order
Request 25 kg bag packing for distributor resale or project supply
Request full-container pricing with palletized export packing
Human review
Compliance notes
Request current SDS, COA, TDS, product label, packing list, commercial invoice, and certificate of origin before shipment
Confirm CAS number and polymer identity because the source page lists CAS 9005-05-8, which may require reconciliation with supplier documents and buyer import records
Verify HS code; source page lists HS 39069010, but buyer should confirm with customs broker based on exact grade and destination country
Confirm dangerous goods classification from SDS; many polyacrylamide powders may ship as non-DG, but this must be document-based and route-specific
For water treatment use, request residual acrylamide data and any applicable food-contact, potable-water, or wastewater-use declarations only if required by the destination market
No regulatory approval or import acceptance should be assumed from marketplace listing claims
If intended for oilfield/EOR use, confirm whether additional technical documentation, end-use statement, or destination-country controls apply
