Polyacrylamide PAM Powder for Paper Mill White Water, Retention and Drainage Applications
Water-soluble polyacrylamide powder candidate for paper mill wet-end retention, drainage, white water recovery and sludge-related process checks. Buyer review should prioritize CAS verification, ionic type selection, molecular weight and charge density confirmation, residual acrylamide limits, solid content, solubility, particle size, export documents and packing suitability before RFQ placement.

Package and route
Packing notes
Source packing options include 25 kg kraft paper bag and 25 kg PE bag
Request pallet configuration, liner details, moisture protection and container loading quantity for export shipments
Confirm bag labeling language, batch number visibility, production date and shelf-life marking
Ask whether neutral export packing, branded packing or buyer-specified labels are available
For humid routes, request details on anti-caking controls, sealed inner bags and desiccant policy if applicable
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
Paper machine wet-end retention program screening
Drainage improvement trials for high-speed paper production
White water suspended solids flocculation and fiber/filler recovery evaluation
Papermaking sludge dewatering aid selection
Replacement or alternate-source qualification for existing PAM grades
Distributor portfolio expansion for paper mill additives
How we compare
Sourcing options
Request anionic PAM, cationic PAM and nonionic PAM samples for comparative jar testing
Ask for grade matching against the buyer's current PAM specification or COA
Source by molecular weight, ionic degree, residual monomer limit and particle size rather than product name alone
Start with lab sample, then pilot lot, then container-level order after performance and document review
Request export-ready documentation package before confirming purchase order
Consider long-term supply agreement if batch consistency and lead time meet mill requirements
Human review
Compliance notes
Verify correct CAS number, product name and polymer identity across quotation, COA, SDS, TDS, invoice and customs documents
Request current SDS in the buyer-required language and format before shipment
Confirm residual acrylamide monomer specification and test method, as acrylamide-related impurity limits may affect buyer acceptance and local compliance review
Confirm HS code; source lists HS 39069010, but importer should validate final classification with customs broker
Check DG status with the latest SDS and carrier review; PAM powder is often shipped as non-dangerous cargo, but dust, moisture sensitivity and local classification still require document confirmation
For papermaking applications, request confirmation of suitability for the intended paper grade, furnish system and wet-end chemistry without relying on general performance claims
If used in regulated paper grades or water-related systems, buyer should request applicable declarations such as food-contact, heavy metals, SVHC/REACH, RoHS, ZDHC or regional statements where relevant
No regulatory approval, import clearance or end-use acceptance should be assumed from marketplace listing data
