Dioctyl phthalate (DOP) prices have softened in parts of Asia, weighed down by sluggish downstream demand sentiment. Market participants reported that slower offtake from flexible PVC processing, particularly in construction-linked applications, has put downward pressure on prices in the region during October 2026.

Despite firm feedstock costs in some markets, weak buying interest and ample supply have limited sellers’ ability to hold price levels. Traders noted that converters are operating conservatively, purchasing only on a need-basis while monitoring broader economic conditions. The cautious tone reflects ongoing uncertainty in end-use demand, with many market participants expecting prices to remain range-bound until clearer signs of demand recovery emerge.
