Biomass Nanofiber

BiNFi-s: Biomass Nanofiber

 "BiNFi-s" is a biomass nanofiber with a diameter of about 0.02 μm and length of a few μm. It is produced by processing cellulose, chitin, and chitosan using our unique Ultrahigh-pressure water jet technology.
 This biomass-derived nanofiber makes use of features such as a low linear thermal expansion coefficient, high elastic modulus, transparency, biocompatibility, anti-bacterial properties, and improvement effects of physiological functions. Applied development of this nanofiber is progressing in various fields including the chemical, medical, pharmaceutical, and health food fields.

 Compared with the raw materials, "BiNFi-s" provides an increase in the specific surface area of over a hundred times and a maximum viscosity of more than 70,000 mPa sec. It exhibits useful effects in various applications and possesses characteristics such as a porous structure, high strength, high crystallization, and low linear thermal expansion. In addition, one major feature is the fact that the nanofibers are produced using water alone without any acid or alkali.
 "BiNFi-s Cellulose" makes use of various features such as having the same low linear thermal expansion characteristics as quartz glass, a high strength that is five times that of steel like aramid fibers, and a transparency provided by fibers with a diameter less than 1/10 the visible wavelength. It is being used as a functional material to improve the resin strength by mixing it with the resin, and to improve the film barrier properties, etc. Furthermore, "BiNFi-s Chitin" and "BiNFi-s Chitosan" are also being applied in cell culture substrates, wound covering material, and health foods due to their excellent biocompatibility characteristics.
 Sugino Machine manufactures and sells BiNFi-s cellulose, chitin, and chitosan products in concentrations of 2, 5, and 10%. In addition, we also provide a variety of fibers for food and other products.

Features

  1. Gentle on the environment and the human body
    This nanofiber creates harmony with the environment and the human body since it uses only water and biomass.
  2. Excellent and diverse properties
    It has excellent properties such as a high strength, low thermal expansion, deposition, transparency, and porosity.
  3. High aspect ratio and high degree of crystallinity
    A high aspect ratio and a high degree of crystallinity is achieved using our unique ultrafine technology.
