Silica Microparticles

In addition to the polymer based particles we now offer a range of silica particles offering unique properties:

  • Density: 1.8-2 g/cm3
  • Refractive Index: 1.37
  • Hydrophilic anionic surface
  • Narrow size distribution
  • Temperature resistance up to 1000°C
  • Good mechanical stability 
  • Stable in organic solvents
  • Soluble in strong bases and in hydrofluoric acid
