PriceSeek analysis of propylene oxide, long-short score: -1. The ex-factory price of propylene oxide decreased by 100 yuan per ton to 7,700 yuan per ton compared to the previous day, with the unit operating normally, indicating stable market supply but weak demand or relatively sufficient supply, which generally exerts bearish pressure on spot prices. The price decline reflects supply-demand pressure in the spot market, possibly due to weakening downstream demand or intensified industry competition, increasing the risk of downward pressure on spot prices in the short term.
