Possessing the CAS number 9003-05-8, this compound is synthesized from acrylamide monomers and is supplied primarily in a convenient powder form.
It finds extensive utility across numerous industrial sectors due to its ability to efficiently separate solids from liquids and modify rheological properties.

The functional mechanism of Polyacrylamide is rooted in its chemical structure.
The presence of amide groups (-CONH2) along the polymer chain allows PAM to form hydrogen bonds with suspended particles in aqueous systems.
This interaction facilitates the adsorption of the polymer onto multiple particles simultaneously, creating a 'bridging' effect.
These bridges aggregate the smaller particles into larger, heavier flocs, which settle out of the suspension more readily.
This process is fundamental to clarification and dewatering applications.

Polyacrylamide is not a single entity but comes in various types, each tailored for specific applications and charge conditions.
The main classifications include Anionic Polyacrylamide (APAM), which is negatively charged and effective in systems where particles carry a positive charge; Cationic Polyacrylamide (CPAM), positively charged, ideal for negatively charged particles or sludge dewatering; and Nonionic Polyacrylamide (NPAM), which carries minimal or no charge and is often used where charge interactions are not dominant or in high salinity environments.
The choice of Anionic, Cationic, or Nonionic PAM is critical for optimizing performance in a given process.

The applications of Polyacrylamide are vast and impactful across diverse industries.
In Water Treatment, PAM is indispensable for clarifying raw water, treating municipal and industrial wastewater, and facilitating sludge dewatering.
Its ability to quickly aggregate suspended solids significantly improves the efficiency of sedimentation, filtration, and centrifugation processes, leading to cleaner effluent and reduced disposal costs.
In the Oil and Gas industry, PAM is used in drilling fluids to control viscosity and reduce friction, in enhanced oil recovery (EOR) as a mobility control agent to improve sweep efficiency, and in fracturing fluids.
The Paper Making industry utilizes PAM as a retention and drainage aid, improving fiber and filler retention on the paper machine, enhancing dewatering, and increasing dry and wet paper strength.
It is also used in the treatment of paper mill wastewater and deinking processes.

Further applications include Mining and Coal Washing, where it is used as a clarifier for wastewater and tailings.
In the Textile industry, PAM serves as a sizing agent and antistatic additive.
The Sugar Making process benefits from PAM's ability to accelerate the sedimentation of impurities, aiding in the clarification of sugar juice.
It also finds use in applications like soil stabilization, incense making, and leather processing wastewater treatment, demonstrating its wide-ranging utility as a versatile industrial chemical.

Effective use of Polyacrylamide typically involves preparing a dilute solution, often between 0.1% and 0.3% (W/W), before dosing into the system.
The optimal dosage varies widely depending on the specific application, the nature of the wastewater or suspension, and desired outcome, usually ranging from 0.1 to 10 ppm.
Jar tests are commonly employed to determine the most effective type and dosage for a particular situation, ensuring efficient flocculation and rapid sedimentation.
Proper handling minimizes dusting, and storage in cool, dry conditions is essential to maintain product quality, with a typical shelf life of two years under recommended conditions.
Packaging commonly includes 25kg bags or larger bulk bags.

Sourcing high-quality Polyacrylamide (PAM) powder is essential for achieving optimal performance in any application.
Finding a reputable manufacturer and supplier is a key step in securing a consistent and reliable source.
Factors such as the Polyacrylamide PAM price, product specifications (like ionic charge and molecular weight), and packaging options are important considerations when looking to buy Polyacrylamide (PAM).
Establishing a strong relationship with a trusted partner simplifies the purchase of Polyacrylamide and ensures technical support and product consistency are available.
Reliable manufacturers provide detailed product data sheets and application guidance, helping users maximize the benefits of this essential industrial polymer.
