This daily report, based on the method of mean difference analysis and a comprehensive assessment of the latest spot quotes and industry chain data, concludes: The current DOP price is at a high point in its 1-year cycle. In the short term, the trend shows a strong rebound with a bias towards volatility. The continuous decline observed in late September has temporarily halted. Going forward, it will be crucial to closely monitor changes in the prices of upstream raw materials such as 2-ethylhexanol and phthalic anhydride, as well as the demand for DOP as a plasticizer in downstream PVC applications.
