  • How is the polyacrylamide (PAM) market performing in 2024?
  • Track polyacrylamide (PAM) price trends and forecasts for the top ten countries worldwide. North America, quarter ending March 2024 The North American polyacrylamide (PAM) market continued to decline in the first quarter of 2024, with prices falling to $2,375 per metric ton (FOB - Texas) by the end of March.
  • Why did acrylamide prices rise in China?
  • There was high-cost pressure due to rise in the raw material acrylamide costs resulting in a surge in polyacrylamide (PAM) prices in the Chinese market. China, the largest exporter of PAM, faced limited inventories, thus fewer exports. The demand of PAM from the downstream industries like water treatment, paper industry remained healthy.
  • 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.
  • How did the APAC polyacrylamide market perform in Qingdao?
  • APAC In the first quarter of 2024, the APAC polyacrylamide (PAM) market witnessed a downward price movement, with March prices settling at USD 850 per MT on FOB – Qingdao basis, indicative of a challenging quarter.
