February 25 News: On February 24, Hualu Hengsheng's BDO units will undergo scheduled rotation maintenance: the first-line 120,000-ton/year unit is planned to be shut down by the end of February 2026, with a maintenance period of approximately 20 days; the second unit will undergo rotation maintenance as scheduled, with an expected period of about 20 days. Chempricehub analysis of 1,4-butanediol, long-short rating: 1.5. Hualu Hengsheng's BDO unit rotation maintenance (first-line 120,000-ton/year unit shut down for 20 days, second unit rotation maintenance for 20 days) will significantly reduce the spot supply of 1,4-butanediol. Tight supply may drive up spot prices, as demand remains relatively stable, with strong positive factors. However, the maintenance period is short and partially planned, and market expectations have been partially digested, hence the rating of 1.5 (between moderate and significant positive impact).
