Polyacrylamide (PAM ANIONIC)

Description

1. Product Overview
Anionic Polyacrylamide (PAM) is a high-molecular-weight water-soluble polymer synthesized via copolymerization of acrylamide and anionic monomers. It is primarily used as a high-performance flocculant, coagulant aid, and friction reducer in industrial solid-liquid separation processes. The key value proposition is its ability to drastically reduce sludge volume and improve water clarity at lower dosages than conventional inorganic coagulants. Strategically, this product is critical for industries facing tightening environmental discharge regulations, enabling compliance while lowering total operational expenditure.

2. Key Specifications & Technical Characteristics

• Chemical Composition: Copolymer of Acrylamide (AM) and Sodium Acrylate (or other anionic monomer)

• Anionic Degree (Hydrolysis %): Available in low (5–15%), medium (15–30%), and high (30–45%) ranges; standard grade offered at 20–30% ±2%

• Molecular Weight (Mw): 15–25 million g/mol (ultra-high range for superior bridging flocculation)

• Purity Level: Active solid content ≥ 90% (minimum 88% for technical grade)

• Physical Form: White granular powder (20–80 mesh), or micro-beads (free-flowing, low dust)

• Bulk Density: 0.75 – 0.85 g/cm³

• Residual Monomer (AM): < 0.05% (food-grade / toxicologically safe standard; meets EU REACH)

• pH Stability (solution): Effective range for flocculation: pH 6.0 – 8.5; functional range: pH 5.0 – 10.0

• Solubility Time: < 45 minutes in cold water (at 0.1% concentration, 20°C)

• Packaging Options: 25 kg net multi-wall kraft paper bags (PE liner), 750 kg FIBC big bags, or 1,000–1,200 kg shrink-wrapped pallets

• Shelf Life: 24 months when stored below 35°C in original sealed packaging, away from humidity and UV

3. Core Industrial Applications

• Primary Industries: Mining & mineral processing; municipal & industrial wastewater treatment; oil & gas (EOR – enhanced oil recovery); pulp & paper; textile; food processing

• Operational Use Cases:

  • Mining (thickening & tailings dewatering): Flocculates fine suspended solids (clay, slimes) in CCD circuits and paste thickeners → achieves >60% faster settling rates vs. non-ionic PAM.

  • Wastewater treatment (primary & secondary clarifiers): Bridges suspended organic/inorganic particles → reduces sludge volume index (SVI) by 40% and lowers TSS to <30 ppm.

  • Paper making (retention & drainage): Increases fiber and filler retention by 15–20%, reduces white water solids.

• Performance advantage: Anionic PAM outperforms aluminum sulfate (alum) at neutral-to-alkaline pH without adding corrosive metals; it requires 5–10× lower dosage than inorganic coagulants for equivalent turbidity removal.

4. Competitive Advantages

• Quality consistency: Every production batch tested for molecular weight, anionic degree, residual monomer, and solubility; ISO 9001:2025 and NSF/ANSI/CAN 60 certified.

• Supply reliability: Dual-source manufacturing (Asia & Middle East) with 10,000 MT monthly capacity; safety stock held in Rotterdam, Houston, and Shanghai.

• Logistics capability: Door-to-door delivery via break-bulk, 20’/40’ containers, or flexitanks for liquid emulsions (powder version offered here).

• Price competitiveness: Direct ex-plant pricing reduces distributor markups by 18–25% compared to European and US legacy brands.

• Sustainability: 100% residual monomer controlled below 0.02%; product aids in water reuse, reducing freshwater extraction by up to 70% in closed-loop systems.

• Technical support: Free jar testing protocol, onsite pilot trials, and custom molecular weight tailoring available for orders >20 MT.
