Title: Wenzhou Yingyue New Materials Expands High-Purity Hydrogen Sulfide Production Capacity to Meet Global Semiconductor Demand

Release Date: May 21, 2026

WENZHOU, China – Wenzhou Yingyue New Materials Co., Ltd. (www.yycheme.com), a leading specialty gas manufacturer and supplier based in Zhejiang Province, has announced a significant expansion of its high-purity hydrogen sulfide (H₂S) production facilities. The company is investing RMB 20 million in new production lines that will increase its annual capacity of 5N (99.999%) high-purity hydrogen sulfide to 800 tons by the end of 2026.

This expansion comes in response to the surging global demand for high-quality specialty gases in semiconductor manufacturing, where even trace impurities can compromise wafer quality and device performance. As chip manufacturers transition to smaller node sizes below 7nm, the requirement for ultra-high-purity process gases has become increasingly stringent.

"Our advanced distillation purification technology allows us to consistently produce 5N (99.999%) grade hydrogen sulfide, which meets the mainstream specifications of the global semiconductor industry," said a spokesperson for Wenzhou Yingyue New Materials. "We are continuing to invest in R&D to further improve product stability and purity levels, and are working closely with industry partners to validate our products in real-world manufacturing environments."

In addition to hydrogen sulfide, the company produces a comprehensive range of specialty gases including hydrogen bromide (HBr), sulfur dioxide (SO₂), boron trifluoride (BF₃), nitrogen trifluoride (NF₃), and various industrial gases. All products are manufactured in accordance with international quality standards and are exported to over 25 countries worldwide.

The company's state-of-the-art facilities in Shandong and Zhejiang provinces feature clean production workshops and rigorous quality control systems. Wenzhou Yingyue New Materials also provides complete gas handling solutions, including specialized steel cylinders, valves, and accessories designed for safe and efficient gas delivery.
