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
