Applications
1. For Water And Wastewater Treatment: Polyacrylamide (PAM, CAS 9003-05-8) is a widely used water-soluble polymer flocculant that bridges and aggregates suspended particles in municipal and industrial wastewater, accelerating sedimentation and filtration while supporting efficient sludge dewatering.
2. For Papermaking: In paper manufacturing, PAM works as a retention and drainage aid and a paper strength enhancer, improving fiber and filler retention, increasing sheet strength and helping mills run cleaner, more efficient production lines.
3. For Oilfield And Drilling Applications: In oil and gas operations, polyacrylamide is used in drilling fluids and enhanced oil recovery (EOR) as a viscosifier and friction reducer, helping control fluid loss, improve wellbore stability and raise recovery efficiency.
4. For Mining And Mineral Processing: PAM serves as a flocculant in mineral processing, coal washing and tailings treatment, speeding up solid-liquid separation and reducing water consumption and environmental load in concentrator operations.
5. For Textile And Industrial Formulations: In textile processing, PAM is used for sizing and color fixation, and it also acts as a thickener and stabilizer in various industrial formulations, giving manufacturers a versatile water-soluble polymer across multiple sectors.
Quality Assurance
Every batch of chemicals leaves our factory with complete laboratory documentation — not a promise, but verifiable test data. From incoming raw material inspection to finished-goods release, each batch is tested against published specifications, and a Certificate of Analysis (COA) accompanies every single shipment. What you order is exactly what we test — and what we ship.
Tested by our in-house ISO 9001:2015 laboratory. Verified independently by third-party labs on request (SGS / BV / Intertek). Traceable from raw material to your warehouse.
