进入2026年，在供需矛盾缓和及出口表现向好等因素支撑下，丁酮市场触底反弹，华东地区丁酮现货报 价集中于6300～6350元(吨价，下同)。然而，本轮涨势并非市场筑底完成的信号，在核心矛盾难以化解 的前提下，丁酮市场或将复制2025年的疲软走势，全年市场均价存在创近年新低的风险。 供应弹性或成常态 生意社分析指出，丁酮市场持续处于近年低位区间的核心原因，在于供应面始终保持充裕。2025年，国 内丁酮总有效产能已攀升至109.7万吨，创下历史新高。其中，正丁烯水合法产能为84.7万吨/年，醋酸 仲丁酯法产能为25万吨/年。 相较于前几年，正丁烯水合法丁酮企业的利润空间已明显收缩。通常情况下，只有当市场价格逼近成本 线时，主要生产企业才会被迫降负荷运行或停车检修，行业借此实现短期好转，丁酮利润也仅在局部时 段出现一定修复。而另一工艺路线——醋酸仲丁酯法丁酮企业的盈利能力更弱，2025年多数时间处于亏 损状态，因此这类企业多以切换生产醋酸仲丁酯为主。 金联创分析师杨广智认为，2026年醚后碳四大概率延续弱势运行态势。丁酮企业成本压力减轻的同时， 个别时段或存在获利空间扩大的可能，但盈利改善将刺激存量产能满负荷释放及 ...

Core Viewpoint - Caprolactam is primarily used for producing nylon, with continuous growth in nylon capacity since 2011 driving the sustained establishment of caprolactam capacity in China. By 2024, China's caprolactam capacity is expected to reach approximately 6.94 million tons per year, with a production of 6.543 million tons and a consumption of 6.49 million tons per year. Entering 2025, the downstream demand for caprolactam is expected to slow significantly, leading to "weak costs, weak demand, and high inventory" pressures, causing prices to drop to a low point. In response, the caprolactam industry has initiated a "de-involution" process, with industry association members agreeing to implement a 20% production cut and raise product prices by 100 yuan per ton. It is believed that with the continued execution of "de-involution" measures, the supply-demand structure of the caprolactam industry is expected to improve [1][4]. Production and Demand Summary - In 2024, China's caprolactam capacity is projected to be around 6.94 million tons per year, with a production of 6.543 million tons and a consumption of 6.49 million tons per year. New capacity additions in 2024 will total 1.15 million tons per year, including new installations from Hunan Petrochemical (300,000 tons/year), Luxi Chemical (300,000 tons/year), Hubei Sanning (400,000 tons/year), and Hualu Hensheng's capacity expansion [2][3]. - The compound annual growth rate (CAGR) for caprolactam consumption from 2021 to 2025 is 13.5%, although demand growth rates will vary by year. Demand growth is expected to be robust in 2023-2024, but will significantly slow in 2025, leading to pressures of "weak costs, weak demand, and high inventory" [2][3]. Industry Response - The caprolactam industry has initiated a "de-involution" process due to increasing issues of overcapacity and price chaos. An industry meeting on November 5, 2025, confirmed the urgency of this initiative, with participants agreeing to implement a 20% production cut and raise prices by 100 yuan per ton. As of late October to early November, the caprolactam supply side has seen increased maintenance of some facilities, reducing capacity utilization to around 86%, and the weekly supply-demand balance has turned negative, alleviating some inventory pressure [3][4].
