KPPC Advanced Chemicals started work on Phase I of a $120 million chemical manufacturing plant in Casa Grande. The project will be built at the Sonoran Valley Industrial Park.

With the initial Phase 1 investment, the facility will produce ultrapure chemicals and proprietary functional chemicals used throughout semiconductor fabrication, wafer cleaning, etching, CMP, photolithography, and advanced packaging. Production is anticipated to begin in late 2027. The construction phase will also generate hundreds of contractor and supplier opportunities across Pinal County and Greater Phoenix.

KPPC expects the Casa Grande site to grow into a full semiconductor chemical campus, with total investment projected to reach approximately $500 million by 2035.

Upon startup, the UAP facility will supply TSMC, Intel, Micron, and other world-class chipmakers across the United States with high-purity materials required for the next generation of logic and memory technologies.
