On February 2, Sinopec North China provided no quotation for diethylene glycol. Tianjin Petrochemical's 42,000-ton/year unit remained shut down, while Yanshan Petrochemical's 80,000-ton/year unit had no restart plan, and both units have been completely removed from production capacity. PriceSeek's analysis of diethylene glycol shows a long-short score of 1.5. The article indicates that Tianjin Petrochemical's 42,000-ton/year unit is shut down, and Yanshan Petrochemical's 80,000-ton/year unit is out of operation with its capacity removed, resulting in a total supply reduction of 122,000 tons/year. Combined with Sinopec North China's lack of quotations, this suggests a significant tightening of market supply. The supply shortage is expected to drive up the spot price of diethylene glycol, as reduced supply amid stable or increasing demand reinforces bullish expectations, benefiting the spot market.
