Material Safety Data Sheet - Amorphous Silica
Microspheres and Nanospheres
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.
Coating: Optional Silicone Coating (Dimethylpolysiloxane)
