High-performance natural material (additive): cellulose nanofiber slurry
It is a natural-derived high-performance additive that has functions such as high viscosity and high transparency, which are superior to conventional additives that do not exist in traditional products.
"AUROVISCO" is a water dispersion of ultra-fine wood fiber cellulose nanofiber (CNF) with a fiber width of 3nm. By adding a small amount to water-based liquid agents, the following outstanding functions are expected to be imparted. <Functions> - High transparency - High viscosity - dispersion stability - Water retention - Coating stability function - Thixotropy <Applications> - Thickening and dispersing agents for paints and inks: dispersion stability of pigments and additives / coating film stability - Cleaning and disinfectant solutions: dispersion of abrasives, etc., and coating film stability after application of liquid agents - Ceramic products such as concrete: reinforcing effect for ceramic products *The Oji Group has adopted the "phosphate esterification method" as an effective technique to reduce the energy required for fine processing during manufacturing. This method has enabled the production of high-quality (high transparency, high viscosity, thixotropic) cellulose nanofibers with higher production efficiency compared to conventional methods. In 2017, the cellulose nanofiber production facility began operation at the Oji Paper Tomioka Plant.
