Results of joint research on cellulose nanofibers published online in the U.S. scientific journal Science Advances

第一工業製薬, Osaka University, the University of Tokyo, the Japan Agency for Marine-Earth Science and Technology, and others jointly developed a method for turning aggregates of cellulose nanofibers (CNF) into a plastic-like material that can be molded using heat. The results are scheduled to be published in the online edition of the US scientific journal Science Advances on 16 May 2026.

The reasons the company gives

The company's own explanation, not something inferred from the numbers.

CNF has excellent properties, including high strength, low thermal expansion and high thermal conductivity. However, it has traditionally lacked thermoplasticity, making it difficult to mold into complex shapes or products with large cross-sectional areas.
