  • Product Detail
  • Inquiry


FSUNTM  low specific surface area fumed silica  is a specially designed white-color process modifier consisting of spherical, nano and submicron particles of amorphous silicon dioxide. The nature of the product allows excellent dispersion of these particles in the polymer matrix. This leads to improved distribution of all compound ingredients and a better flow, allowing higher extrusion speeds, better compression set, better resilience and smoother surface of the end product. 


It is mainly used as polymer additive products for  rubber compounds, thermoplastics and coatings. 

Packaging, storage and transportation

Tons of bag packaging, 150kg-600kg specifications.  According to non-toxic, non-dangerous goods storage and transportation.
