Recently, the cost of Phthalic Anhydride in China has been affected by the weakening prices of crude oil, ortho-xylene, and industrial naphthalene, leading to reduced support. The demand for downstream plasticizers is weak, and prices have been declining slightly for several consecutive days. Current indicators suggest that Phthalic Anhydride is in a short-term Weak Rebound (bearish) fluctuation pattern, with prices at a high point in the 1-year cycle. The potential for further price increases is limited. It is recommended to closely monitor the price fluctuations of upstream raw materials and changes in the operating demand of the downstream plasticizer industry.
Data Explanation
The latest available Phthalic Anhydride data for China is up to November 8, 2026. It is recommended to refer to real-time data.
I. Table of Finite Differences
| Mean Difference Indicator | Value on November 8, 2026 | Value on November 7, 2026 | Direction of Change |
|---|---|---|---|
| 5-Day Mean Difference (D5) | -70 | -116.66 | + |
| 10-Day Mean Difference (D10) | -75 | -50 | - |
| 20-Day Mean Difference (D20) | 6.67 | 22.5 | - |
II. Signal State Determination
When the three consecutive divided differences change in the direction combination (+,-,-), it constitutes a Weak Rebound (Bearish) signal.
III. Conclusion on Trend Direction
The short-term price trend is oscillating (with a bearish bias), because the changes in the three mean differences from the previous day are not entirely consistent, meeting the criteria for an oscillating market. The corresponding signal is Weak Rebound with a bearish bias, indicating a higher probability of downward movement in the short term.
4. Location and Spatial Reference
Phthalic Anhydride prices are at moderate-to-high levels on the 60-day cycle, and at high levels on both the 3-month and 1-year cycles, leaving limited room for further increases and subjecting them to significant downward pressure.
VI. Fundamental Analysis Support
Recent crude oil prices have been fluctuating and declining, with the prices of raw materials such as phthalic anhydride and industrial naphthalene weakening, leading to a reduction in cost support for phthalic anhydride. The operating load of phthalic anhydride manufacturers in China has increased, and the supply of spot goods is stable. However, the demand from the downstream plasticizer industry has weakened, and there is insufficient support from rigid demand. Since November, phthalic anhydride quotes in regions such as Shandong and Jiangsu have been continuously reduced.
