Polydisperse Silica Microspheres 1.67g/cc d50=4-8um - Porous Silica Beads
Polydisperse Silica Microspheres 1.67g/cc d50=4-8um - Porous Silica Beads

Polydisperse Silica Microspheres 1.9-2.2g/cc, Optional Dimethylpolysiloxane Coating

Product Line: SiO2MS-PD

Polydisperse silica microspheres are porous ceramic spherical beads. Uncoated silica spheres exhibit excellent dispersibility, good oil absorbancy, and good fluidity. They are used in emulsion and make-up products, as anticaking agents and additive and perfume carriers. Optional silicone coating makes the spheres very hydrophobic, transparent, easy to disperse, resistant to acids and alkalis, resistant to UV and moisture.
