- Hunan Zhenghong Science and Technology Develop Co.,Ltd. (000702.SZ) engages primarily in the research, development, production, and sale of electronic chemicals and new materials, with a focus on high-purity reagents and precursors for semiconductors, displays, and solar applications. The company offers core products including high-purity electronic gases such as silane, ammonia, and boron trifluoride; wet chemicals like hydrogen peroxide, sulfuric acid, and photoresist removers; and specialty gases and precursors under brands tailored for LED epitaxy, photovoltaic cells, and flat-panel displays; it also provides semiconductor cleaning agents, coating materials, and lithium battery electrolyte solvents. Headquartered in Zhuzhou, Hunan Province, China, the company was founded in 1996 and operates primarily in China, serving domestic semiconductor manufacturers, panel producers, and new energy firms, with expanding distribution through subsidiaries in key industrial zones.
In recent developments, Hunan Zhenghong has pursued strategic expansions including a 2024 partnership with a leading domestic semiconductor equipment maker to co-develop next-generation precursor gases; completed a RMB 500 million funding round in early 2025 led by state-backed investors to scale production capacity for OLED display materials; and launched new high-purity tungsten hexafluoride products in late 2024 to capture growing demand in 5nm chip fabrication. The company acquired a minority stake in a Hunan-based rare earth chemicals firm in mid-2025 to secure supply chains for advanced materials; reorganized its R&D division into a dedicated new materials institute to accelerate innovation in perovskite solar cells; and expanded operations with a new facility in Changsha targeting export markets in Southeast Asia. These initiatives position Hunan Zhenghong within the electronic chemicals segment of China's burgeoning semiconductor and new energy industries, targeting enterprise customers in electronics manufacturing and renewable energy sectors.
