Elkem Silicones Materials (Zhongshan) Co., Ltd., located in the Zhongshan Torch Hi-Tech Industrial Development Zone, Guangdong Province, is a wholly owned subsidiary established by Elkem AS of Norway in China. Elkem AS was fully acquired by China Baowu Steel Group in 2021 and is now part of the Elkem Global system. Founded in 2006, the company specializes in the research, development, production, and sales of high-performance silicone monomers, intermediates, and functional materials, operating as a manufacturing enterprise within the advanced fundamental materials and critical strategic materials sectors. Its core business covers five application areas: encapsulation adhesives for new-energy-vehicle power battery packs; long-lasting sealing materials for photovoltaic modules; electronic-grade silicone adhesives for 5G communications; medical-grade silicone rubber; and green building energy-saving sealing systems. Its clients include leading domestic and international enterprises such as Contemporary Amperex Technology Co., Limited (CATL), BYD, Sungrow Power Supply Co., Ltd., China Energy Investment Corporation, Bosch, and Samsung SDI. The company’s core capabilities encompass end-to-end process development and industrialization—from chloromethane to methylchlorosilanes to DMC/D4 and finally to formulated end-use adhesives—supported by an intelligent production line with an annual capacity exceeding 80,000 metric tons of silicone intermediates and deep-processed products. Full-process traceable quality control is achieved via an integrated digital system combining Distributed Control System (DCS), Manufacturing Execution System (MES), and Quality Management System (QMS). The company holds 17 authorized invention patents and 9 utility model patents. Key technologies include optimization of highly selective direct synthesis of methylchlorosilanes and controllable crosslinking of low-VOC high-temperature vulcanizing (HTV) silicone rubber. Its “Two-Component Addition-Cure Liquid Silicone Rubber for Power Battery Modules” received certification as a Guangdong Provincial High-Tech Product in 2024. The company has obtained integrated certification under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018; holds the “National Industrial Product Production License” (for silicone products) and the “Level-II Standardized Enterprise for Work Safety” certificate; complies with EU REACH SVHC regulations; and has passed the IATF 16949 automotive supply chain audit (for designated automotive-grade production lines). Representative achievements include supporting CATL and BYD’s power battery packaging solutions for over 120 GWh of production capacity from 2023 to 2025; completing industrial validation of the sub-project “Development of Highly Reliable Silicone Encapsulation Materials” under China’s National Key R&D Program; and implementing a demonstration project for domestic substitution of photovoltaic power station sealing materials for China Energy Investment Corporation (with outdoor performance verification meeting 15-year service-life requirements). The company serves all provincial administrative regions across mainland China and exports UL/VDE/TÜV-certified industrial-grade and electronic-grade silicone materials to Thailand, Vietnam, South Korea, and Germany.
