## About

Based in Tianjin, China and founded in 2024 by Kang Liu, Tianjin Huaxin Sealing Technology Co., Ltd., trading as Huaxin Sealing Technology, is a high-end sealing material developer, primarily engaged in the research and development of high-end perfluoroethylene sealing materials for the semiconductor and opto electronic display industries.
In September 2026, Huaxin Sealing Technology raised a Series A funding led by Shangshi Fund and other investors, with participation from Shanghai State-owned Capital Investment.
Its main products include perfluoroethylene seals, static seals, pipeline seals, pendulum valve seals, and other specialized sealing products for semiconductor/panel manufacturing processes, applied in high-end manufacturing industries such as semiconductor integrated circuits, LCD panels, and opto electronic displays.
The company generates revenue by doing R&D, and providing perfluoroethylene sealing materials and other related products.
The Series A funding round will be used to expand production lines for FFKM (perfluoroelastomer) sealing materials, validate products against semiconductor SEMI standards, enlarge the R&D team, and drive market expansion, thereby helping to break the overseas monopoly on high-end seals.
