Tokuyama Strengthens Electronic High-Purity IPA Production Capacity in Taiwan

Tokuyama Corporation decided at its board of directors meeting today to construct a second plant for electronic high-purity isopropyl alcohol (hereinafter "high-purity IPA") at its consolidated subsidiary, Formosa Tokuyama Advanced Chemicals Co., Ltd. (hereinafter "FTAC").

Since establishing FTAC in October 2020 as a joint venture with Formosa Plastics Corporation for the manufacturing and sales of high-purity IPA, the company has developed its business in Taiwan. As the miniaturization and stacking of semiconductor manufacturing processes advance, customer demand for the quality and stable supply of high-purity IPA has further intensified. By leveraging the Tokuyama Group's three strengths in the high-purity IPA business—"proprietary manufacturing technology," "high analytical capability," and "strict quality control know-how"—the company aims to further enhance its market presence by strengthening its stable supply system through the expansion of production capacity.
