WSG-H100 cellulose is a kind of high-performance nanofiber, which has the properties of thickening thixotropy, regulating flow and forming film. WSG-H100 is made by depolymerization, sodium modification, etherification, purification, physical oscillation and other processes of specific plant fibers, with the minimum oscillation size reaching nanometer level. WSG-H100 has excellent mechanical stability, thermal stability and acid-base tolerance, and is suitable for use in emulsion and paste.
