solid, hollow and nanoporous glass microspheres with sol-gel technology

for paints, coatings, plastics and energy applications.


Disruptive process

Using sol-gel technology.

Customization options

Numerous customization options : specific formulations, organic/inorganic hybrids…

Low-carbon footprint

Unlike conventional glass microspheres manufacturing, our ambient temperature process has a low-carbon footprint.


Glass microspheres are of two types, solid (also known as glass beads) or hollow (also known as glass bubbles) ; they are used as fillers across various industries, including transportation, building and construction, cosmetics, paper…

Beyond the usual functions of use, such as lightweighting and abrasion resistance, imagine how our microspheres can enhance your product properties. They can be designed and developed to meet your specific needs and technical requirements.
