February 27th News: On February 27th, Zhuhai Changcheng's 50,000-ton/year acetone-based isopropanol plant was shut down, with the specific restart time yet to be determined. Chempricehub's analysis of isopropanol indicates a bullish-bearish score of 1. The shutdown of Zhuhai Changcheng's 50,000-ton/year acetone-based isopropanol plant has resulted in a reduction of approximately 50,000 tons/year in production capacity, and the uncertain restart time has increased market supply uncertainty. This directly benefits the spot price of isopropanol, as the supply contraction may drive up short-term prices, especially given stable downstream demand. Although the scale of the shutdown is not particularly large, regional supply gaps could lead to procurement tightness, supporting the upward trend in spot prices.
