polymer based flocculants review of water purification,for instance, in the case of kaolinite suspensions with neutral ph, any pam flocculant, independent of mw or charge type and concentration, can accomplish successful flocculation; however, only a small number of pam flocculants with very precise properties (e.g., very high mw, anionic medium charge) can stimulate flocculation of oil sands

  • How much does polyacrylamide cost in the US?
  • North America The prices of Polyacrylamide declined in the USA market during the third quarter of 2022, with cost ranging at USD 2252/tonne Polyacrylamide Anionic Grade FOB Texas with a quarterly decline of 11.1% as per recorded by ChemAnalyst pricing team data.
  • Why did polyacrylamide prices remain firm in India?
  • In India, the prices of Polyacrylamide remained firm, driven by the global uptrend on the raw material front. Trade momentum remained muted amid volatile raw material prices in July and pressured demand fundamentals.
  • Why is the demand for polyacrylamide declining in China?
  • The decline in demand from the downstream Wastewater, Paper, and Pulp industries has deteriorated the market sentiments of Polyacrylamide in the domestic region of China. On the upstream cost front, the Acrylonitrile and Acrylic Acid prices have tumbled, diminishing the manufacturing costs of PAM.
  • What is the price of polyacrylamide anionic grade FOB Qingdao?
  • The latest price of polyacrylamide anionic grade FOB Qingdao, China, was $1120/ton in the fourth quarter of 2023. Overall, the market dynamics of PAM in the Asia-Pacific region are affected by the reduction in global crude oil production, oversupply of products, and weakening demand from key industries.
