1. Product Overview
Polyacrylamide (PAM) is a high-molecular-weight, water-soluble synthetic polymer built from acrylamide units (C₃H₅NO)ₙ. It is supplied as white granular powder or emulsion and is the most widely used organic flocculant in the world, operating by adsorption and bridging of suspended particles across a huge molecular-weight range — from a few million up to more than 20 million Daltons.
PAM's performance is tuned by two dials: molecular weight and charge. Nonionic, anionic and cationic grades carry different charge densities to match the particles being treated, which is why one polymer family serves municipal sludge dewatering, industrial wastewater, papermaking, oil recovery and mineral processing. Its long, flexible chains adsorb onto particles and link them into fast-settling flocs — the physical basis of almost every PAM application.
A single polymer family, four core value propositions:
Water & Wastewater Treatment:
● the standard flocculant and sludge dewatering aid for municipal and industrial plants;
Papermaking:
● a retention, drainage and strength aid for paper and board production;
Oilfield & Mining:
● a polymer-flooding agent for enhanced oil recovery and a flocculant for mineral processing;
Textile & Specialty Uses:
● a sizing, thickening and soil-conditioning polymer for diverse industrial applications.

3. Key Features & Benefits
● Fast floc formation and settling: produces dense, fast-settling flocs that clarify water and thicken sludge quickly.
● Effective sludge dewatering: dramatically improves cake dryness and reduces dewatering cost in belt presses and centrifuges.
● Retention and drainage in paper: raises filler/fines retention and machine drainage, cutting furnish cost and energy use.
● Versatile across industries: one product family serving water, paper, oilfield, mining, textile and soil applications.
4. Main Applications
4.1 Water & Wastewater Treatment (Core Application)
PAM is the workhorse flocculant of the water industry:
● Sludge dewatering: cationic grades condition municipal, paper and industrial sludge for belt presses, filter presses and centrifuges;
● Industrial wastewater: anionic and nonionic grades clarify steel, electroplating, metallurgical, coal-washing and dyeing effluent;
● Drinking-water treatment: low-residual-monomer grades serve as coagulant aids in clarification;
● Clarification and settling: accelerates particle settling in clarifiers, thickeners and ponds.
4.2 Papermaking
● Retention and drainage aid: retains fine fibers, fillers and pigments on the wire while speeding up drainage;
● Dry-strength agent: improves paper strength and formation uniformity in specialty grades;
● Process water treatment: clarifies white water and effluent in the paper mill.
4.3 Oilfield & Mining
● Enhanced oil recovery: polymer flooding and profile control thicken injected water to sweep more oil from reservoirs;
● Drilling fluids: viscosity and filtration-control additive in water-based drilling muds;
● Mineral processing: flocculates tailings and concentrates in coal, copper, gold and iron ore beneficiation.
4.4 Textile & Specialty Applications
● Textile sizing: film-forming size for warp yarns, reducing breakage in weaving;
● Thickening and rheology control: stabilizer and thickener for aqueous formulations and drilling/cementing fluids;
● Soil conditioning: improves water retention and erosion resistance of sandy and disturbed soils;
● Friction and drag reduction: reduces pipeline friction in water-transfer systems.
5. Packaging, Storage
Packaging (customizable):
● 25 kg multi-wall paper bag with PE liner, or 500 kg – 1,000 kg FIBC;
● Moisture-barrier lining standard for powder grades.
Storage:
● Keep in a cool, dry, well-ventilated area away from direct sunlight and heat;
● Keep powder containers tightly closed — PAM absorbs moisture and can agglomerate;
● Recommended storage temperature 5 °C – 35 °C; use within shelf life (typically 12 – 24 months).
● Factory-direct supply: own production capacity, transparent pricing, no middleman markup;
● Stable quality: strict internal control, every batch tested, COA with every shipment;
● Export experience: familiar with sea/air shipping documentation for chemical commodities, complete paperwork support;
● Fast response: quotations and technical support (COA, dosage and dissolution advice) within 24 hours; small trial orders accepted.
PAM is a high-molecular-weight water-soluble flocculant. Its largest use is municipal and industrial wastewater treatment (flocculation, clarification and sludge dewatering); it is also used in papermaking as a retention/drainage aid, in oilfields for polymer flooding and drilling fluids, in mineral processing for tailings and concentrates, and in textile and soil applications.
