- Anhui Estone Materials Technology Co., Ltd. (688733.SS) engages in the research, development, production, and sale of advanced inorganic non-metallic composite materials, primarily serving the new energy, electronics, and communications sectors. The company offers lithium battery coating materials for cell diaphragms and electrodes, including boehmite-based products that enhance thermal management and safety; electronic communication functional filling materials such as boomstone, silica powder, spherical aluminum powder, 5G high-frequency copper clad laminate fillers, thermal conductive interface materials, and electronic ink additives; and low-smoke halogen-free flame-retardant materials, including smoke suppression agents, ceramic flame retardants, and B1-rated sheathing solutions. Its products support applications in new energy vehicles, consumer electronics, artificial intelligence, high-speed rail, aeronautics, and chip manufacturing, with exports to international markets and key clients including CATL.
Founded in 2006 and headquartered at No. 10, Jinhe Road, Huaiyuan Economic Development Zone, Bengbu City, Anhui Province, China, the company listed on the Shanghai Stock Exchange STAR Market in August 2021. It operates primarily in China with a global market presence, particularly holding approximately 42% share in boehmite shipments as of 2024.
In recent developments, the company achieved 31,000 tonnes of boehmite shipments in 2024, up 34% year-over-year, and projects over 40,000 tonnes in 2025 amid improved product structure and capacity utilization. It advanced new product initiatives, including construction of a 20,000 tpa high-purity quartz (HPQ) production line for single-crystal applications, multi-batch verification of low-α spherical alumina leading to anticipated small-batch shipments in 2025, and progress on solid-oxide fuel cell (SOFC) stack pilot production with demonstration projects planned for 2025. On November 24, 2025, its Board of Directors authorized a share buyback plan, while R&D breakthroughs extended to brain-computer interface materials like non-invasive gel electrodes integrated with AI for industrial and healthcare uses.
