Zeon invests in Mizushima GPI facility to strengthen C5 business competitiveness

This will increase the production capacity of dicyclopentadiene (DCPD) by approximately 20% from current levels. DCPD is the main raw material for Cyclo-Olefin Polymers (COP) and COP optical film, which are key products and growth drivers of Zeon’s C5 business, as well as other products. As a result of this investment, we will be able to secure a stable supply of DCPD without increasing production of piperylene and other materials used in commodity chemicals. The new facility will also utilize previously unused components, thereby contributing to the reduction of CO2 emissions. Construction will begin the second half of fiscal 2026 and is scheduled for completion in September 2028.
