As China's semiconductor industry accelerates, the localization of key components has become a focal point. Shanghai Xinmi Technology Co., Ltd. has recently entered the inquiry stage for its IPO on the STAR Market. Its core products—semiconductor-grade perfluoroelastomer seals and high-performance fluorosilicone materials—have attracted widespread attention across the industry chain. In the front-end process of chip manufacturing, sealing the vacuum reaction chamber is critical. Beyond breakthroughs in perfluoroelastomers, Xinmi Technology's product line deeply covers key base materials such as Liquid Fluorosilicone Rubber and Solid Fluorosilicone Rubber. These materials are indispensable in wafer manufacturing processes due to their excellent chemical corrosion resistance and high-temperature tolerance. To enhance material purity and processing performance, the industry is placing increasingly stringent requirements on upstream raw materials. High-quality Fluorosilicone Raw Gum, as the base polymer, has molecular weight distribution control that directly determines the final seal's resistance to plasma etching. Additionally, to meet lubrication and release agent needs for different processes, high-purity Ethyl Silicone Oil and Fluorosilicone Oil are widely used in semiconductor equipment auxiliary systems to ensure cleanliness and stability in the production environment. Industry experts point out that with the expansion of domestic foundry capacity, demand for high-performance Fluorosilicone Rubber and its upstream Fluorosilicone Raw Gum will continue to rise. The maturation of the local supply chain will provide a solid guarantee for national semiconductor security.
