ADEKA to Build TRANSPAREX Clarifier Plant in South Korea

ADEKA CORPORATION will build a new manufacturing plant for its TRANSPAREX clarifier at the Jeonju No. 3 Plant of subsidiary ADEKA KOREA CORPORATION in Wanju-gun, North Jeolla Province. The investment is 6.5 billion yen, with 5,996 square meters of total floor area, groundbreaking in December 2026, construction completion in June 2028 and commercial operation starting in November 2028. The plant supplements existing contract manufacturing to secure supply as demand grows, and the group targets a clarifier market above 50 billion yen by fiscal 2030.

Key facts

Market context

Clarifiers, also called nucleating agents, are additives blended into polypropylene to make the resin clearer and stiffer while speeding up crystallization during molding. They matter most in food packaging, medical disposables and automotive interior and exterior parts, where appearance, dimensional stability and processing speed all count. Demand also rises as brand owners and recyclers push for mono-material polypropylene packages that can be recycled without separating layers, since clarifiers help reach performance levels that multi-material structures would otherwise provide. Producers of specialty additives typically rely on a mix of in-house plants and contract manufacturing. Adding dedicated capacity reduces exposure to third-party schedules and quality control, and it can shift the competitive balance among additive suppliers that serve polyolefin compounders and converters. For buyers, supply security and consistent grade quality tend to matter as much as list price in this segment.
