Core Viewpoint - The recent price increases of MDI (Methylene Diphenyl Diisocyanate) by major chemical companies are driven by rising raw material costs, production disruptions, and increased demand for lightweight materials in various industries [3][4]. Price Increases - Major chemical companies including BASF, Huntsman, Wanhua Chemical, and Dow Chemical have announced significant price hikes for MDI products across Europe, Asia, and Africa, with increases reaching up to €350 per ton [3]. - Specific price adjustments include BASF raising prices by $200 per ton in South Asia, Wanhua Chemical increasing prices by $200 per ton in Southeast Asia and South Asia, and Huntsman announcing a €350 per ton increase in Europe, Africa, and the Middle East [3]. Reasons for Price Increases - The price hikes are attributed to several factors: fluctuations in international oil prices raising core raw material costs, increased transportation and energy costs, and compliance pressures [4]. - Additionally, 45% of China's MDI production capacity is undergoing maintenance, which includes major plants from Wanhua and BASF, leading to reduced output [4]. - The demand for MDI is also supported by trends in building insulation materials, a recovery in home appliance exports, and the growing need for lightweight materials in the electric vehicle sector [4]. Capacity Expansion - Wanhua Chemical is accelerating its MDI capacity expansion project in Fujian, expected to add 700,000 tons of capacity by Q2 2026, potentially increasing its global market share to 42% [4]. - Mitsui Chemicals announced plans to further increase its MDI production capacity by 10,000 tons per year, following a recent expansion that brought its total capacity to 610,000 tons [5]. Environmental Considerations - Mitsui Chemicals is also focusing on reducing greenhouse gas emissions by utilizing a recovery system during its capacity expansion, aligning with global efforts to improve building insulation performance and combat climate change [5]. Supply Chain Developments - The production process for MDI at Mitsui Chemicals has been enhanced through the implementation of advanced technology, which has improved the efficiency of chlorine production and reduced waste [6].
