In May 2025, the Board of Directors of Asahi Kasei Corporation decided to exit the businesses of methyl methacrylate (MMA) monomer, cyclohexyl methacrylate (CHMA), polymethyl methacrylate (PMMA) resin (product names: DelpetT and DelpowderTM), and styrene-butadiene latex, and to reallocate its acetonitrile supply framework (closing its refining plant in Kawasaki, Japan).
One of the fundamental strategies of Asahi Kasei's current mid-term management plan for fiscal years 2025-2027, "Trailblaze Together," is to improve investment efficiency through structural transformation and increased productivity. This decision is part of a broad review of the business portfolio and a reallocation of operating resources in accordance with this fundamental strategy.
Asahi Kasei's PMMA resin, styrene-butadiene latex, and acetonitrile businesses began in 1963, and its MMA monomer business started in 1974. These products were all manufactured at the company's plant in Kawasaki, Japan, and have been supplied to customers worldwide for over half a century.
In recent years, high raw material costs and declining market competitiveness have led to a continued slump in these businesses, with factory operating rates remaining consistently low. Ultimately, Kawasaki's factory decided to cease production of these products. Upon hearing this news, industry peers across the supply chain expressed regret.
