Chongqing Double Elephant Electronic Materials Co., Ltd. was established in November 2019. It is a technical production enterprise specializing in the research and development, production, and sales of high-quality sulfuric acid. It has a newly built electronic-grade sulfuric acid project with an annual output of 1 million tons. It covers an area of about 120 acres and has 3 newly built sulfuric acid production lines. The main products are electronic grade sulfuric acid, 98% sulfuric acid, and 104.5% oleum. It can produce 1 million tons of sulfuric acid per year. Electronic-grade sulfuric acid, also known as high-purity sulfuric acid and ultra-pure sulfuric acid, is an ultra-clean and high-purity reagent and is an indispensable key basic chemical reagent in the development of microelectronics technology. Electronic-grade sulfuric acid is widely used in microelectronics industries such as large-scale integrated circuits (ICs) and semiconductors as cleaning and etching agents. With the rapid development of China's microelectronics industry, the demand for electronic-grade sulfuric acid is increasing day by day.

    The company is the second step in the strategic development of Chongqing Changshou Production Base and plays a key role in connecting the past and the future. It provides high-quality sulfuric acid products to Chongqing Yixiang, develops the field of electronic acid itself, and provides steam and other public works for subsequent projects such as microfiber materials. . It can not only solve the needs of its own downstream enterprise Chongqing Yixiang, but also drive the development of the park and local economy.
