Polyacrylamide(PAM)
Overview of PAM
Polyacrylamide (PAM) is a high-molecular-weight polymer used globally in B2B settings for flocculation, thickening, and water clarification. Available in anionic, cationic, nonionic, and amphoteric forms, it helps industrial buyers improve processes in water treatment, oil & gas, and more. Key benefits include cost-effective performance and low residual toxicity, with typical packaging in 25kg bags for easy export. For compliance, products often align with ISO 9001 for quality and REACH for safety in international markets.
Choosing the Right Grade
Match PAM grade to your application’s pH and material charge: anionic for alkaline wastewater, cationic for acidic sludge. Typical specs include solid content over 89% and dissolution under 90 minutes. Start with low dosages (e.g., 0.1-5 mg/L) and adjust based on testing.
Safety and Handling Tips
Store in cool, dry areas with a 2-year shelf life. Use gloves and masks during handling; it’s non-toxic but slippery when wet. Follow local regulations like RoHS for electronics-related uses.
