- 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.
- What are the different types of polyacrylamide water treatment?
- Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.
- Why did polyacrylamide (PAM) prices increase in Q4?
- Prices of Polyacrylamide (PAM) increased effectively during this quarter across North America region, supported by firm offtakes from the downstream sectors. The demand for Polyacrylamide remained firm throughout the quarter, taking support of firm offtakes from paper pulp and water treatment sector.
- Why is the polyacrylamide (PAM) market declining?
- North America The Polyacrylamide (PAM) market in North America during the fourth quarter of 2023 witnessed a declining trend, primarily due to reduced demand in key downstream industries such as industrial water treatment and the Oil Gas Enhanced Oil Recovery (EOR) sector.
