Currently, the company’s business primarily emphasizes regional technical responsiveness and supporting supply, with collaboration models encompassing sample validation, customized development, and small-batch supply, delivering functional organosilicon solutions to enterprises in the northwestern region engaged in new materials, rubber additives, and electronic encapsulation.

Jiangyin Huali Industrial Gases Co., Ltd. is located at No. 38 Xinggang Road, Gangkou Subdistrict, Jiangyin City, Jiangsu Province. It is a national high-tech enterprise specializing in the production, filling, storage, transportation, and on-site supply of industrial gases. Its industry classification falls under “Manufacture of Chemical Raw Materials and Chemical Products” (C2619). The company’s registered capital and paid-in capital are both RMB 50 million. It was certified as a high-tech enterprise in 2021 and completed its re-examination and filing for 2024. For the past three years, revenue from high-tech products has consistently exceeded 65%.  

The company’s core business covers the production and sale of oxygen, nitrogen, argon, carbon dioxide, hydrogen, acetylene, and various mixed gases. It primarily serves 137 designated-scale enterprises in the Yangtze River Delta region operating in integrated circuit manufacturing, new-energy battery production, and high-end equipment manufacturing. Among its clients are 19 A-share listed companies. Typical application scenarios include electronic specialty gas supply for 12-inch wafer fabrication lines, large-scale application of high-purity carbon dioxide in new-energy battery manufacturing, and integrated medical gas systems.  

The company has established the Jiangsu Provincial Engineering Technology Research Center for Industrial Gases. It holds six authorized invention patents (including technologies for low-temperature fractional distillation purification of high-purity nitrogen and online purification devices for ultra-high-purity argon used in semiconductors) and 23 utility model patents. Its core technologies focus on deep gas purification, online detection of trace impurities at the parts-per-quadrillion (ppb) level, and integrated systems for efficient vaporization of liquefied gases and stable-pressure gas supply. Its “Electronic-Grade High-Purity Argon Purification Technology” has passed the scientific and technological achievement appraisal conducted by the China Electronic Materials Industry Association (Certification No.: ZDCLJZ [2023] No. 017).  

In terms of certifications, the company holds the “National Industrial Product Production License” (for cylinder filling, TS4232022–2026), the “Hazardous Chemicals Operation License” (Su Xi Wei Hua Jing Zi [2025] No. 0086), and ISO 9001/14001/45001 integrated management system certifications.
