About This Product

Cellulose NanoFiber (hereinafter referred to as CNF) is wood fiber (pulp) that has been refined to nano-order (one millionth of 1 mm). CNF is an excellent material that is transparent, light, durable, resistant to deformation, and has a high thickening effect, and is used in many fields such as replacing plastics, carbon black, and other conventional materials, and adding new functions. We look forward to seeing you in action. Cellulose nanofiber (CNF) is a biomass material made from wood fibers, the raw material for paper, that have been refined down to the nanometer (nm) level.

■Phosphate esterified CNF

We have adopted the ``phosphoric acid esterification method'' as an effective method to reduce miniaturization energy during manufacturing. This method has made it possible to produce CNF of high quality (high transparency, high viscosity, and thixotropy) with higher production efficiency than conventional methods. We started operating our CNF demonstration manufacturing facility in 2017. Currently, we are manufacturing a variety of CNF, including transparent CNF slurry "AUROVISCO" and coarse CNF slurry, and are actively providing samples and developing applications for commercialization. Because CNF is extremely hydrophilic, it is difficult to mix with organic solvents and resins. We have developed a "hydrophobic CNF powder" that uses proprietary technology to reduce the water content of CNF and increase the solid content to a maximum of 90wt%. As a result, we succeeded in dispersing CNF in various organic solvents, which was previously difficult. Like an aqueous dispersion, this dispersion is highly transparent and highly viscous, so it is expected to be applied to improve the elastic modulus by combining with resin, improve the rheology of paints and inks, and synthesize various organic solvents. .
