CelluloSysTM :
  • Proprietary CNF technology
  • A unique solution for a variety of applications

CNF is a material composed of nanosized cellulose fibrils with a high aspect ratio (length to width ratio). Typical fibril widths are 5–20 nanometers with a wide range of lengths, typically several micrometers. The fibrils are isolated from any cellulose contain-ing source including wood-based fibers (pulp fibers) through high-pressure, high temperature and high velocity impact homo-genization, grinding or microfluidization.

Cellulose, the unfibrillated material, is an important structural component of the primary cell wall of most plants and one of the most abundant natural polymer that is bio-compatible and even edible. Cellulose is only used to mainly produce paperboard and paper. Smaller quantities are converted into a wide variety of de-rivative products such as cellophane and rayon. Conversion of cellulose from energy crops into biofuels such as cellulosic et-hanol is under development as a renewable fuel source. Above these usages, high-end applications can be realized when it is converted into CNF.

What is unique about our CNF materials?

Inorganic nanomaterials (SiO2, TiO2, ZnO, ZrO2, FeOx, others)
Cellulose nanofiber
According to our technology, inorganic nanomat-erials are in-corporated on the surface of CNF under controlled chemical reaction condition. This new material called mCNF, a mineralized CNF, provides well-dispersion without making aggreg-ation upon plastic composition and high stability during high temperature thermal processing. In addition, a special property can be harnessed by properly choosing the inorganic species adopted.
