About the product

Carbon nanofiber with high crystallinity synthesized with the vapor phase method. Superior in thermal conductivity, electrical conductivity, strength property and slidability (lubricity). Due to its fiber diameter larger than that of carbon nanotube, it can be easily handled (dispersion, etc.) and used for wider purposes.

  • With an extremely small average fiber diameter (150nm), functions as excellent filler with thermal conductivity, electrical conductivity, strength, and slidability.
  • Chemically stable, with small specific surface area and with minute amount of absorption moisture.
  • With almost 10 years of mass production performance, quality is stable.
