Polyacrylamide (PAM) Series
CPAM • APAM • NPAM • Emulsion PAM
Direct global manufacturer of ultra-high molecular weight water-soluble linear polymers located in Shandong. Engineered for high-efficiency municipal sewage sludge dewatering, industrial wastewater clarification, and oilfield EOR.
Cationic Polyacrylamide (CPAM)
Synthesized by copolymerizing cationic monomers with acrylamide, CPAM is a linear organic polymer with positive electric charges. It excels in organic sludge dewatering, rapid clarification, and solids-liquid separation across municipal and industrial applications.
- High charge density and adaptable to varying wastewater conditions.
- Customizable ionic degree (Low, Medium, High) for specific belt or centrifuge presses.
- Manufactured by Shandong Hongtai Chemical under stringent ISO quality controls.
| Appearance | Solid Content | Molecular Weight | Ionic Degree | Dissolution |
|---|---|---|---|---|
| White Granules | ≥ 88% | 5 – 17 Million | Low / Medium / High | ≤ 60 Mins |
Anionic Polyacrylamide (APAM)
APAM is an ultra-high molecular weight polymer (exceeding 30 million Daltons) produced by copolymerizing acrylamide and acrylate salts. It exhibits exceptional adsorption, bridging, and charge neutralization capabilities for inorganic particle flocculation.
- Extremely fast settling velocity and clear supernatant water clarity.
- Low residual monomer content (<0.05%) – safe and environmentally friendly.
- Widely applied in Tertiary Oil Recovery (EOR) and sand washing.
| Appearance | Solid Content | Molecular Weight | Hydrolysis Degree | Dissolution |
|---|---|---|---|---|
| White Granules | ≥ 88% | 4 – 35 Million | Low / Medium / High | ≤ 60 Mins |
Non-ionic Polyacrylamide (NPAM)
NPAM is a homopolymer of acrylamide featuring high purity, neutral charge, and high molecular weight. Because its chain carries almost no ionic charges, its flocculation efficiency is virtually unaffected by water pH levels or dissolved salt concentrations.
- Superior flocculation under acidic conditions compared to hydrolyzed APAM.
- Acts as a high-performance soil moisturizer and desert sand-fixation film-former.
- Versatile industrial uses: textile sizing agent and coating binder.
| Appearance | Solid Content | Molecular Weight | Ionic Degree | Dissolution |
|---|---|---|---|---|
| White Granules | ≥ 88% | 3 – 13 Million | ≤ 5% | ≤ 90 Mins |
Emulsion-Type Polyacrylamide (W/O Liquid)
Produced using advanced Water-in-Oil (W/O) emulsion technology, these high-concentration liquid PAM flocculants are available in Anionic, Cationic, and Non-ionic types. They feature rapid dissolution, uniform molecular weight distribution, and effortless automated dosing.
- Ultra-Fast Dissolution: Fully dissolved in just 5 to 15 minutes.
- Eliminates powder dust hazards and prevents dissolution equipment clogging.
- Ideal for high-throughput automated dosing plants.
| Product Type | Solid Content | Viscosity | pH Value | Dissolution |
|---|---|---|---|---|
| Anionic W/O Emulsion | 30% – 50% | 3 – 9 | 5 – 8 | 5 – 10 Mins |
| Cationic W/O Emulsion | 35% – 50% | 1 – 6 | 3 – 7 | 5 – 15 Mins |

Frequently Asked Questions (FAQ)
Powder PAM should be stored in a cool, dry, and well-ventilated warehouse protected from moisture and direct sunlight. Emulsion PAM should be stored sealed between 5°C and 30°C to prevent freezing or thermal degradation.
Dry powder granules maintain stable chemical performance for up to 24 months from the manufacturing date. Emulsion-type liquid PAM has a recommended shelf life of 12 months under proper storage conditions.
Emulsion-type PAM features ultra-fast dissolution within 5 to 15 minutes. Solid Cationic (CPAM), Anionic (APAM) dissolve within ≤ 60 minutes, while Non-ionic PAM (NPAM) requires ≤ 90 minutes.
