Polyacrylamide Manufacturer China — APAM, CPAM, NPAM & PHPA
ChinaPAM is a factory-direct polyacrylamide manufacturer in China, supplying anionic (APAM), cationic (CPAM), nonionic (NPAM), and oilfield (PHPA) grades from our Henan manufacturing base. For buyers comparing polyacrylamide manufacturers and suppliers in China, this page is the starting point: pick the PAM type below, review the verified buyer facts, then move to the grade-level specification pages. Powder grades use a public baseline of ≥90% solid content; exact residual monomer and other parameters should be confirmed by grade and batch COA.

Anionic Polyacrylamide
APAMCharge: Negative (anionic)
Molecular weight: 3-28 million
Best for: Municipal & industrial wastewater, raw-water clarification, coal washing, mineral tailings thickening, EOR.
Choose APAM when suspended solids are the target and the water carries mostly inorganic or negatively balanced particles.
View APAM grades & specs →Cationic Polyacrylamide
CPAMCharge: Positive (cationic)
Molecular weight: 6-16 million
Best for: Sewage sludge dewatering, belt press and centrifuge conditioning, oily wastewater, paper retention.
Choose CPAM for organic sludge with negative surface charge, where charge neutralization drives dewatering.
View CPAM grades & specs →Nonionic Polyacrylamide
NPAMCharge: Neutral (nonionic)
Molecular weight: 3-15 million
Best for: Mineral processing, acidic or high-salinity effluent, soil conditioning, and general suspended-solids removal.
Choose NPAM when the water is acidic or ion-heavy and ionic PAM would lose charge activity.

PHPA / SpecialtyCharge: Application-specific
Molecular weight: Grade-specific
Best for: Drilling fluids (PHPA), food-processing wastewater grade, and other application-matched formulations.
Choose specialty grades when the process needs viscosity control, salinity tolerance, or a specific compliance profile.

Buying Polyacrylamide Direct From the Manufacturer
Factory-direct pricing
Ordering from the manufacturing base rather than a trading layer keeps grade selection, batch documentation, and pricing in one place.
Grade matching first
We match molecular weight (APAM/NPAM) or charge density (CPAM) to your process before quoting, instead of quoting a single generic grade.
Sample before bulk
Free samples let you run jar tests on your own water or sludge before committing to a bulk order.
Export documentation
Grade-specific TDS, batch COA, and SDS support customs clearance and internal QA review. Compare the supplier profile or the MOQ and pricing guide.
Frequently Asked Questions
What is polyacrylamide (PAM) and what is it used for?
Polyacrylamide is a high-molecular-weight water-soluble polymer used mainly as a flocculant and coagulant aid. It bridges and neutralizes suspended particles so they settle or dewater faster. Core applications are municipal and industrial water treatment, sludge dewatering, mining and mineral processing, oil & gas (enhanced oil recovery and drilling), and paper making.
How do I choose between anionic, cationic, and nonionic polyacrylamide?
Anionic PAM (APAM) targets suspended solids in clarification and mining. Cationic PAM (CPAM) targets organic sludge dewatering where charge neutralization matters. Nonionic PAM (NPAM) suits acidic or high-salinity water where ionic grades lose charge. When in doubt, send your application, water chemistry, and solids data and we will recommend a starting grade before pricing.
What is the MOQ, lead time, and packaging for PAM 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 a plastic liner or 25 kg PE bags. Free samples are available before bulk confirmation.
How should I compare 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 water, slurry, or solids data before quoting. A useful PAM quote should match application and molecular-weight or charge-density range before price comparison.
What documents can I review before a bulk PAM order?
Buyer review can include grade-specific TDS, batch COA, and SDS for the exact PAM grade under discussion. Free samples are available before bulk confirmation so jar testing can happen before finalizing the order.
What is the typical dosage rate for polyacrylamide?
Dosage depends on application and grade: municipal wastewater 1-3 mg/L, raw-water clarification 0.5-2 mg/L, sludge dewatering 3-8 kg/ton of dry solids, and mining tailings 20-50 g/ton of dry solids. Always run jar tests because dosage varies with water chemistry and suspended solids concentration.
