Dow Permanently Shuts UK Silicone Monomer Plant, Creating Huge Supply Gap in European Silicone Market

Keywords: Dow UK silicone plant shutdown, European silicone supply gap, overseas silicone capacity withdrawal, China silicone export to Europe, DMC export substitution

Key Sentence: Dow’s permanent closure of its 145,000-ton UK silicone monomer factory cuts nearly one-third of Europe’s base silicone capacity, bringing massive export opportunities for domestic silicone manufacturers. On July 16, 2026, Dow Chemical confirmed full shutdown of its Wales silicone monomer plant in the UK, with all production lines completely halted in mid-2026. Persistently high European natural gas costs and aging equipment are core shutdown drivers, removing about 87,000 tons of annual DMC supply from the European market雪球. The plant’s output previously met nearly 88% of China’s total silicone raw material exports to Europe, forming a large supply vacuum. European downstream sealant, electronic and automotive silicone buyers accelerate supplier audits of Chinese manufacturers to fill the gap. Industry institutions forecast China’s silicone product export volume to Europe will rise over 22% in Q4 2026. Domestic factories with REACH-compliant low-D4 silicone formulas will gain priority bulk orders, while the long-term supply pattern of Europe relying on Asian silicone imports is further solidified.
