On December 30, Shandong Zhuohang New Materials (Heze) Co., Ltd. announced a price reduction of 50 yuan/ton for propylene glycol, down from its original price of 5350 yuan/ton. PriceSeek analyzed the situation with propylene glycol and gave a negative score of -1. The report indicates that the supply side has taken the initiative to lower the quoted price of propylene glycol by 50 yuan/ton to 5350 yuan/ton, likely due to weak demand or increased inventory pressure, which will negatively impact spot prices. Although the decrease is only about 0.93%, it reflects a short-term market supply and demand imbalance, suggesting that spot prices are expected to face downward pressure.
