Nonionic Polyacrylamide Factory China for Acidic Ore Processing and Coal Washing
ChinaPAM is a factory-direct nonionic polyacrylamide manufacturer in China, shipping NPAM from our Henan production base. Nonionic PAM works where anionic and cationic types cannot — in acidic environments below pH 6. For buyers comparing nonionic polyacrylamide factories in China, these grades cover gold, copper, and iron ore processing, coal washing fine coal recovery, and acid mine drainage treatment. Zero ionic charge means no interference with mineral surfaces during flotation. Powder grades use a public baseline of ≥90% solid content; exact residual monomer and other parameters should be confirmed by grade and batch COA.
Start from the polyacrylamide manufacturer hub to compare APAM, CPAM, and NPAM, or send your pH and slurry data through Request Quote for a starting grade before pricing.

MOQ 500 kg, free samples, standard lead time 7-10 days, T/T or L/C, and 25 kg kraft or PE packaging for common export orders.
Technical checks
Send your pH, slurry chemistry, solids load, and equipment so the starting molecular weight can be matched to your acidic process before pricing.
Documents
Buyer review can include TDS, batch COA, and SDS for the exact grade under discussion.

Quick NPAM Selection Guide
Use this shortlist to choose a starting NPAM direction before sample testing and final grade confirmation.
| Application | Starting Grade | Selection Focus |
|---|---|---|
| Gold / copper leaching (acidic) | Medium MW NPAM | Prioritize settling in low-pH CIL/CIP and heap leach solutions where ionic PAM loses charge. |
| Coal washing fine coal recovery | Medium MW NPAM | Balance fine coal capture and clarity of recycled process water. |
| Acid mine drainage treatment | Medium MW NPAM | Confirm dosage by jar test against pH and metal loading before scale-up. |
| Textile / acidic industrial waste | Medium MW NPAM | Match dosage to suspended solids where acidic pH rules out anionic and cationic grades. |

Frequently Asked Questions
When should I use nonionic polyacrylamide instead of anionic or cationic?
Use nonionic PAM when your water/slurry pH is below 6 (acidic conditions). Anionic and cationic PAM lose effectiveness in acidic environments because their ionic charges are neutralized. NPAM has zero ionic charge, so it works reliably at pH 4-8 — making it essential for acid mine drainage, gold/copper leaching, and acidic industrial waste.
What industries use nonionic polyacrylamide?
Primary users: gold mining (CIL/CIP tailings at pH 2-4), copper leaching (acidic heap leach solutions), coal washing (fine coal recovery), iron ore processing, and acid mine drainage treatment. Also used in textile dyeing (acidic dye baths) and food-grade applications where ionic interference must be avoided.
What is the MOQ, lead time, and packaging for NPAM export orders?
The standard trial-order MOQ is 500 kg. Common-grade lead time is usually 7-10 days after order confirmation. Standard export packaging is 25 kg kraft paper bags with plastic liner or 25 kg PE bags. Free samples are available before bulk confirmation so jar testing can happen first.
How should I compare nonionic polyacrylamide manufacturers in China?
Compare manufacturer-backed facts first: MOQ 500 kg, free sample support, T/T or L/C payment scope, 25 kg export packaging, grade-specific TDS, batch COA, SDS, and whether the supplier asks about your pH, slurry, and solids data before quoting. A useful NPAM quote should match your acidic application before price comparison.
What is the price difference between nonionic and anionic PAM?
Nonionic PAM typically costs $1,300-$2,500/ton FOB China, slightly more than standard anionic grades ($1,200-$2,800/ton) because of specialized production requirements. However, in acidic applications where APAM fails completely, NPAM is the only viable option regardless of price.
What documents can I review before a bulk NPAM order?
Buyer review can include grade-specific TDS, batch COA, and SDS for the exact NPAM grade under discussion. Free samples are available before bulk confirmation so jar testing can happen before finalizing the order.
Buying nonionic polyacrylamide from a factory-direct supplier in China
As a nonionic polyacrylamide factory rather than a trading company, ChinaPAM ships NPAM directly from our Henan production base, so bulk and wholesale buyers avoid the markup that layered suppliers add. Whether you are sourcing nonionic polyacrylamide for gold or copper leaching, coal washing, or acid mine drainage, we quote on the grade your acidic process needs, not a one-size-fits-all price. For buyers evaluating nonionic polyacrylamide manufacturers and suppliers in China, the practical comparison points are consistent: confirmed MOQ of 500 kg, free samples for jar testing, 7-10 day lead time on common grades, T/T or L/C terms, and grade-specific TDS, COA, and SDS on request.
Wholesale NPAM orders ship in 25 kg kraft or PE bags with OEM label support available. To move from comparison to a quote, share your pH, water chemistry, and solids load so we can match the right nonionic polyacrylamide grade before pricing. Not sure whether NPAM, APAM, or CPAM fits your process? Start from the polyacrylamide manufacturer hub.
