What Sino Polymer does

Sino Polymer Co., Ltd. (华东理工大学华昌聚合物有限公司) is a Shanghai-headquartered specialty polymer resin manufacturer that originated in 1958 as an enterprise affiliated with East China University of Science and Technology and is majority-owned by state-affiliated Shanghai Huayi Group. The company develops and produces high-performance matrix resins — including the proprietary MFE epoxy vinyl ester resin line (first industrially applied in mainland China in 1975), MERICAN specialty epoxy systems, CIPP trenchless rehabilitation resins, phenolic resins including nuclear-pure grades for 4th-generation reactors, polysulfone resins, and waterborne/solvent-free coatings — across five production bases with approximately 180,000 tonnes of total annual capacity.

The company sells into industrial anti-corrosion, new energy vehicles and hydrogen storage, rail transportation (carbon fiber metro and high-speed rail), ships and marine engineering, aerospace, wind power, photovoltaic, CIPP pipeline rehabilitation, municipal construction, and health/environmental applications. It serves customers such as CRRC Qingdao Sifang, CSIC 725 Research Institute, Sinopec, PetroChina, top-tier Chinese NEV OEMs, Northern European wind turbine OEMs, and Middle Eastern desalination equipment manufacturers, through direct project-based sales combined with a global network of 35 dealers across 35 countries and technology brand licensing arrangements in five countries.

Sino Polymer generates revenue through negotiated, project-specific quotations on customized resin formulations, recognizing revenue upon product delivery. FY2024 revenue reached 689 million RMB (+11.7% YoY), with MFE vinyl ester resin volumes exceeding 22,000 tonnes and export revenue of 170 million RMB (+21% YoY). The company maintains an R&D center and pilot-scale facilities at the Longwu Road headquarters and partners with ECUST, the Shanghai Carbon Fiber Composite Innovation Research Institute, and France's Mäder Group via a 49%-owned joint venture (Shanghai Lili New Materials). Strategic positioning is reinforced by IATF16949, FDA, RoHS, EN 45545-2, TUV Rheinland, CCS, and Lloyd's Register certifications, plus national-level recognition as a "Specialized, Refined, Distinctive, Innovative" small giant enterprise.
