Research and Development
Cellulose NanoFiber (CNF), a wood pulp-derived high functional material, weighs only one fifth of steel but possesses five times the strength of steel. It holds promise for application to various fields, such as automotive parts, films, filters and paper. Businesses and research institutions are competing in a development race for applications of CNF. Daio Paper is working to develop applications and overcome cost barriers toward commercialization of the new material.
