Chempricehub analysis of diethylene glycol, bullish-bearish score: 2. The article indicates that Sinopec East China raised its diethylene glycol offer by 650 yuan/ton, with Shanghai Petrochemical at 3,870 yuan/ton, Yangzi Petrochemical at 3,900 yuan/ton, and Yangba Petrochemical at 3,900 yuan/ton. Concurrently, plant operating rates are low, with a run rate of only about 40%, indicating severe tightness on the supply side. This significant increase directly reflects a shortage in the spot market supply, which will drive up spot prices for diethylene glycol, representing a major positive impact. It is expected that spot prices will rise significantly in the short term, and the tight supply-demand situation in the market is unlikely to ease.
