SOLARTRON functional polymer membranes

SOLARTRON.Founded in 2010 and headquartered in Ningbo, China, SOLARTRON is a world-leading high-tech enterprise specializing in functional polymer membranes, integrating original technology, core patents, and the R&D, production, and sales of core products. The company has consistently aligned itself with national development strategies and industrial policies, adhering to an innovation strategy of “import substitution, global leadership, and top-tier performance.” It promotes the deep integration of scientific and technological innovation with industry, focusing on the development of key functional membrane materials that are heavily reliant on imports and urgently require domestic substitution in specific application scenarios, thereby serving the development of the nation’s strategic emerging industries. In 2012, SOLARTRON entered the optical reflective film market, achieving major breakthroughs in materials, processes, and equipment. The company independently designed and constructed production lines, with products whose comprehensive performance reached internationally leading levels. This successfully filled a domestic gap and broke the technological monopoly held by Japanese and South Korean companies in this field. In 2017, the company surpassed Toray Industries of Japan in market share and has since maintained its leading position as the global market leader (2017–2024). By 2024, its global market share for optical reflective films had exceeded 50%, and its position as the global leader in this segment remained firmly established. Leveraging its robust R&D and industrialization capabilities, SOLARTRON has continuously expanded its product portfolio, which now encompasses optical reflective films, solid-state electrolyte ion-conducting membranes, optical base films, lithium-ion battery separators, and other specialty functional films, providing critical material support for cutting-edge industries such as displays, new energy, and semiconductors.
