Precipitated Silica

We have more than 45 years of experience in research, development, manufacturing and distribution of precipitated silicas, ideal for the following industries:

  • Food industry
  • Toothpaste industry
Precipitated silicas, also called silicon dioxide, are considered inert, non-toxic powders for the human being and the environment. The radiographic analysis shows the typical spectrum of a radiographically amorphous substance, which does not contain crystalline elements. At Glassven we are suppliers of this important raw material wherever your industry is. Contact us now!
