Proshare is a national high-tech membrane enterprise founded by a team of returnee Ph.D. scholars led by a Chinese national-level high-tier overseas talent. The company specializes in the R&D and industrialization of high-end reverse osmosis, nanofiltration, and material separation membranes based on third-generation thin-film nanocomposite (TFN) technology. Dr. Lin Xiaofeng, the founder, has been recognized as a Leading Talent in the Industrial Park, Gusu Leading Talent, Provincial Double-Innovation Talent, and was selected for the National Major Talent Program. He holds over 30 authorized patents.

Approved by the Suzhou Industrial Park Administrative Committee in Jiangsu Province, Proshare established its headquarters in 2017 at Suzhou Nano City, the world's largest nanotechnology industrial application community. The company’s membrane technology industrial park now covers an area of 31,234m2, with over 20,000m2 dedicated to R&D, production, and office space. It employs nearly 100 people, more than 30% of whom are R&D personnel.

As the core business of the company, Proshare has achieved remarkable success in the R&D and industrialization of TFN membranes. By integrating layer-by-layer self-assembly technology and nano-reinforced materials, the R&D team developed a new generation of TFN reverse osmosis and nanofiltration membranes, revolutionizing the previous thin-film composite (TFC) technology pathway. Proshare established China’s first TFN coating production line with an annual capacity of millions of square meters and took the lead in achieving mass production, becoming one of the few specialized membrane suppliers in the world.

Proshare’s TFN membrane products offer advantages such as high flux, antifouling resistance, oxidation resistance, and customized specialty membrane solutions. With a diverse product portfolio, it boasts the industry’s most comprehensive range of high-flux, acid/alkali-resistant, antifouling, oxidation-resistant, and conventional specialty membranes—all independently developed and produced. Supported by a national-level expert application team, Proshare provides industry-leading cost-effective membrane products and technical services. Its solutions have been widely deployed in over 100 industrial projects across sectors including new energy, semiconductors, petroleum and petrochemicals, synthetic biology, seawater desalination, and municipal wastewater reuse. Its clientele includes Fortune 500 companies, large central state-owned enterprises, listed companies, and industry leaders, contributing world-class professional membrane products and technical services to help customers achieve energy savings, emission reduction, resource recovery, and sustainable development.

Adhering to the core values of efficiency, professionalism, win-win sharing, and innovation, Proshare remains committed to technological R&D, continuously integrating and optimizing the upstream and downstream industrial chain, and expanding its applications and market presence. The company is dedicated to leading the development of TFN membrane technology and realizing its vision of becoming a global leader in the high-end separation membrane industry.
