February 5th News On February 5th, Shandong Fuyu Petrochemical Co., Ltd. restarted its 180,000-ton phenol-ketone unit, with premium-grade products expected to be produced. Currently, there is no quotation for bisphenol A. Chempricehub Analysis: **Acetone** Bull-Bear Score: -1 The restart of Shandong Fuyu Petrochemical's 180,000-ton phenol-ketone unit and the production of premium-grade products will significantly increase acetone supply. As the primary product of the unit, the rise in supply will directly exert downward pressure on spot prices, potentially leading to inventory accumulation and price competition. Considering current market demand, this event is generally bearish for acetone spot prices. **MIBK** Bull-Bear Score: -0.5 The restart of the phenol-ketone unit increases acetone supply, which may lower the production cost of MIBK, a downstream derivative of acetone. However, the unit restart does not directly involve MIBK production, and there is a lack of clear positive support on the demand side. Overall, the impact on MIBK spot prices is slightly bearish. The downside price risk is limited, and attention should be paid to subsequent raw material cost transmission.
