Fujian Xinrui secures investment to scale supercritical TPU foaming
The company is expected to use the RMB 100 million (approximately USD 14 million) RMB 100 million (approximately USD 14 million) investment to further scale its supercritical TPU and elastomer foaming operations for both domestic and export markets.
China’s supercritical foaming sector has attracted fresh capital after Putian Furui Xincai Industrial Fund, managed by Huafu Capital, completed an investment of nearly RMB 100 million (approximately USD 14 million) in Fujian Xinrui New Material Technology. The transaction marks the first deployment of capital by the newly established Furui Xincai Industrial Fund, which targets strategic emerging materials industries.
Founded in 2016 and based in the Xianyou Economic Development Zone in Fujian Province, Fujian Xinrui focuses on supercritical fluid physical foaming technologies. The company develops and manufactures polymer foaming beads based on materials including TPU, TPEE and nylon elastomers, as well as steam-molded “popcorn” midsoles and injection-molded supercritical foam components.
Supercritical CO₂ foaming is increasingly used in performance footwear and lightweight structural applications, delivering fine cell morphology, reduced density and improved rebound compared with conventional chemical blowing processes. Fujian Xinrui states it is the first company globally to achieve large-scale mass production of certain dry supercritical foaming materials.
The new investment is intended to accelerate technology development and expand production capacity. Fujian Xinrui has completed construction of a 91-acre production base which, once fully operational, is expected to deliver annual capacity of 20,000 tonnes of microporous foaming beads and 50 million moulded parts.
The company has invested RMB 750 million in total and holds more than 20 invention patents and 33 utility model patents covering its “Gongyu” product series. It operates a joint laboratory with Shandong University dedicated to supercritical fluid microfoaming research and materials development.
The deal reflects continued efforts within China to strengthen domestic capabilities in advanced polymer processing technologies. For the polyurethane sector, supercritical TPU bead foaming represents a growing competitive segment, particularly in athletic footwear and high-performance consumer products, where lightweight elasticity and energy return are key performance drivers.
With new funding in place, Fujian Xinrui is expected to further scale its supercritical TPU and elastomer foaming operations for both domestic and export markets.
