Six polyacrylamide families — all CAS 9003-05-8, ISO 9001 production. Every grade ships with batch COA; TDS downloads are on the Downloads page.
Polyacrylamide (PAM) is a water-soluble synthetic polymer made from acrylamide monomer. By varying molecular weight and ionic character, one chemistry serves sedimentation, clarification, dewatering and mobility control. Choose by your water chemistry and separation goal — or send us a sample and we will choose for you.

Anionic Polyacrylamide (APAM)
White granular powder, 25 kg kraft bag
High-molecular-weight anionic polyacrylamide for sedimentation and clarification. Long polymer chains bridge fine particles into large, fast-settling flocs — the workhorse for tailings thickening, red mud settling, sand washing and industrial wastewater. Supplied in low, medium and high anionicity grades.
Typical applications
- Mining tailings sedimentation
- Alumina red mud settling
- Sand & gravel washing water
- Industrial wastewater clarification
- River dredging slurry
Typical specifications
| Molecular weight | 8–20 million |
|---|---|
| Anionic (hydrolysis) degree | Low / medium / high, 10–35% |
| Solid content | ≥ 90% |
| Residual acrylamide monomer | ≤ 0.05% |
| Dissolution time | ≤ 60–90 min (grade dependent) |
| pH range of solution | 5–14 (best in neutral to alkaline) |

Cationic Polyacrylamide (CPAM)
White granular powder, 25 kg kraft bag
Cationic polyacrylamide for sludge dewatering and organic-rich wastewater treatment. Positive charges neutralize negatively charged colloids and organic matter, forming tight, shear-resistant flocs that release water efficiently on belt presses, centrifuges and screw presses. Charge degrees from 10% to 60%.
Typical applications
- Municipal sludge dewatering
- Paper mill sludge & fiber recovery
- Food & beverage wastewater
- Paint / dye wastewater color removal
- Oil emulsion breaking
Typical specifications
| Molecular weight | 5–12 million |
|---|---|
| Cationic charge degree | 10–60% (graded series) |
| Solid content | ≥ 90% |
| Residual acrylamide monomer | ≤ 0.05% |
| Dissolution time | ≤ 60 min |
| Bulk density | 0.65–0.85 g/cm³ |
HK-N series · CAS 9003-05-8
Nonionic Polyacrylamide (NPAM)
White granular powder, 25 kg kraft bag
Nonionic polyacrylamide keeps its performance where ionic grades collapse: acidic to neutral pH and high-salinity waters. Preferred for textile sizing and finishing, acidic mining water, metallurgical separation and some drinking-water treatment duties.
Typical applications
- Textile sizing & finishing
- Acidic mine water
- Metallurgical separation
- Construction piling slurry
- Clarification of low-alkalinity water
Typical specifications
| Molecular weight | 8–15 million |
|---|---|
| Hydrolysis degree (ionicity) | < 5% |
| Solid content | ≥ 90% |
| Residual acrylamide monomer | ≤ 0.05% |
| Dissolution time | ≤ 60 min |
| pH range of solution | 1–8 (best in acidic to neutral) |
HK-P series · CAS 9003-05-8
PHPA (Partially Hydrolyzed Polyacrylamide)
White granular powder, 25 kg bag / 750 kg big bag
Partially hydrolyzed polyacrylamide engineered for oilfield chemistry: polymer flooding for enhanced oil recovery (EOR), drilling fluid additive and slickwater friction reducer. Ultra-high molecular weight with controlled hydrolysis gives brine tolerance at reservoir salinity and temperature.
Typical applications
- Polymer flooding (EOR)
- Drilling fluid viscosifier & shale inhibitor
- Slickwater fracturing friction reducer
- Profile control & water shutoff
Typical specifications
| Molecular weight | 16–24 million (ultra-high) |
|---|---|
| Hydrolysis degree | 20–30% |
| Solid content | ≥ 90% |
| Filtration factor (EOR grade) | ≤ 1.5 |
| Dissolution time | ≤ 120 min |
| Brine tolerance | grades for 10,000–100,000 mg/L TDS |

Emulsion Polyacrylamide
Milky inverse-phase emulsion, 200 kg drum / 1,000 kg IBC
Inverse-emulsion polyacrylamide that dissolves in minutes instead of hours — no overnight hydration, no fish-eyes. Ideal for plants without dissolution skids, for emergency dosing, and for automated polymer preparation units. Cationic and anionic grades with the same active chemistry as our powders.
Typical applications
- Rapid make-down dewatering
- Emergency clarifier dosing
- Automated polymer units
- Mobile water treatment plants
- Space-constrained facilities
Typical specifications

|---|---|
| Type | Cationic / anionic inverse emulsion |

HK-W series · CAS 9003-05-8
Water Treatment Powder Grade
White fine powder, 25 kg bag with PE liner
High-purity powder grade for potable and municipal water treatment. Low residual monomer and tight viscosity consistency give reliable flocs at very low dosages, with fine particle size for fast, complete dissolution in automated dry-feed systems.
Typical applications
- Raw water clarification (potable)
- Municipal WWTP primary settling
- Automated dry-feed dosing
- Stormwater clarification
