New Cyclo Olefin Polymer production plant

Zeon holds groundbreaking ceremony for construction of new Cyclo-Olefin Polymers production plant to be completed in first half of fiscal 2028 Zeon Corporation (Zeon; head office: Chiyoda-ku, Tokyo; President and CEO: Tetsuya Toyoshima) will begin construction of a new production plant for Cyclo-Olefin Polymers (COP) at its business site in Yuka Town, Shunan City, Yamaguchi Prefecture. The new plant will produce COP in anticipation of growing demand based on its expanding use in medical and semiconductor applications in addition to its optical applications. Full-scale construction will begin in March 2026 toward completion in the first half of fiscal 2028, increasing Zeon’s annual production capacity for COP by about 30% from current levels. In addition, we’ve decided to name this new site the Tokuyama East Plant, and together with our existing Tokuyma Plant (Shuna City, Yamaguchi Prefecture; Plant Manager: Akira Honma), we aim to further expand our operations in the Shunan area.
