Solvay doubles electronic grade H2O2 capacity in Zhenjiang

Solvay officially opened a significant expansion at its Zhenjiang, China, facility, doubling its production capacity for electronic grade hydrogen peroxide (H2O2) annually. This investment underscores Solvay’s commitment to supporting the semiconductor industry, which relies on this ultra-pure chemical for integrated circuit manufacturing.

Solvay has doubled its electronic grade hydrogen peroxide capacity at its Zhenjiang, China site, reinforcing support for the fast-growing semiconductor industry.
The ultra-pure H2O2 is vital for chip cleaning and etching, with purity at parts per trillion levels.
Opened September 15, 2025, the expansion strengthens Solvay’s global leadership in electronic chemicals.

Electronic grade H2O2 is essential for critical cleaning and etching in semiconductor chip production. Achieving its requisite purity is extraordinarily challenging, with impurities measured in single-digit parts per trillion (similar to finding a grain of salt in a soccer fi eld). Only a select number of companies worldwide possess the advanced capabilities and manufacturing processes required to meet these exacting specifications.

This expansion builds upon Solvay’s initial launch of electronic grade H2O2 production at this site in 2018 and directly addresses the escalating demand for these vital materials, as electronic devices continue to advance and the industry strives to keep pace with the number of transistors on integrated circuits doubling approximately every two years.

“This significant capacity increase demonstrates our agility and dedication to customers in the rapidly expanding electronics sector,” stated Carlos Silveira, President of Solvay’s Peroxides business. “Thanks to Zhenjiang’s well-established business environment and specialized support, this expansion strategically positions us to continue supplying critical materials for the next generation of technological innovation. Our INTEROX Pico grades offer industry-leading purity and uniformity, supported by identical manufacturing processes across our global production facilities, which is a crucial factor for semiconductor producers seeking worldwide consistency.”

The inauguration event on September 15, 2025, was attended by Zhenjiang Economic and Technological Development Zone leaders, Solvay CEO Philippe Kehren, and Peroxide GBU President Carlos Silveira. This new expansion, which joins other investments in the US, Europe, and China, further consolidates Solvay’s leadership in the electronic chemicals market, serving critical applications in semiconductors, flat panel displays, photovoltaics, and MEMS/LED fabrication.
