SIDISTAR® for polymers

;
Improving flame retardancy with SIDISTARĀ® 

SIDISTARĀ® is an amorphous (non-crystalline) material, composed of ultrafine spheres of silicon dioxide. It is produced in a gas-phase condensation multi-step process. Elkem has specifically developed SIDISTARĀ® for polymer applications.The median particle size is about 0,15 micron (150 nm), with a low surface area of BET 20 m2/g.

Important application areas

  • Sidistar improving flame retardancy (rubber, plastics)
  • Sidistar improving plate out (plastics)
  • Sidistar improving dynamic fatigue
  • Sidistar improving processing (extrusion)
  • Sidistar improving (fibre) dispersion
