Semiconductor industry demand drives Solvay’s major capacity increase for electronic grade hydrogen peroxide in China

(IN BRIEF) Solvay has doubled production capacity for electronic grade hydrogen peroxide at its Zhenjiang facility in China, responding to surging demand from the semiconductor industry. The ultra-pure material, used for cleaning and etching in chip manufacturing, requires precision down to parts per trillion. The expansion builds on Solvay’s original 2018 investment in Zhenjiang and ensures consistent global supply through identical production processes across its facilities. Executives including CEO Philippe Kehren and Peroxides President Carlos Silveira joined local leaders at the inauguration, which strengthens Solvay’s global position in electronic chemicals for semiconductors, displays, photovoltaics, and LEDs.

(PRESS RELEASE) BRUSSELS, 16-Sep-2025 — /EuropaWire/ — Solvay has officially inaugurated a major expansion at its Zhenjiang facility in China, doubling annual production capacity for electronic grade hydrogen peroxide (H₂O₂). This milestone reinforces Solvay’s role as a key partner to the global semiconductor industry, which depends on this ultra-pure material for critical cleaning and etching processes in integrated circuit manufacturing.

Producing electronic grade H₂O₂ requires extraordinary precision, with impurities measured in parts per trillion—comparable to finding a single grain of salt in an entire soccer field. Only a handful of companies worldwide possess the advanced capabilities to meet such standards, and Solvay’s INTEROX® Pico grades are recognized for their unmatched purity and uniformity.

This expansion builds on Solvay’s initial launch of electronic grade H₂O₂ production in Zhenjiang in 2018 and directly addresses the semiconductor sector’s growing demand, driven by continual advances in electronic devices and the pace of Moore’s Law. Identical production processes across Solvay’s global facilities ensure consistency of supply to semiconductor customers around the world.

“This capacity increase highlights both our responsiveness to the market and our long-term commitment to supporting customers in the fast-evolving electronics sector,” said Carlos Silveira, President of Solvay’s Peroxides business. “With Zhenjiang’s strong business ecosystem and dedicated support, we are well-positioned to supply the ultra-pure materials needed to enable the next generation of technology.”

The opening ceremony on September 15, 2025, was attended by senior leaders from the Zhenjiang Economic and Technological Development Zone, Solvay CEO Philippe Kehren, and Carlos Silveira. The investment adds to Solvay’s ongoing expansion in the United States, Europe, Taiwan, and China, reinforcing its leadership in the electronic chemicals market, which also serves flat panel displays, photovoltaics, MEMS, and LED fabrication.

By scaling production capacity at Zhenjiang, Solvay is addressing the semiconductor industry’s urgent needs while further consolidating its global position as a trusted supplier of critical high-purity materials.
