Fumed Silica

Grades: Industrial
Form: Solid
Category: Products
synonyms: Glut
CAS#: 112945-52-5
Packing: Bags, Super Sacks


Fumed silica also known as pyrogenic silica because it is produced in a flame, consists of microscopic droplets of amorphous silica fused into branched, chainlike, three-dimensional secondary particles which then agglomerate into tertiary particles. The resulting powder has an extremely low bulk density and high surface area. Its three-dimensional structure results in viscosity-increasing, thixotropic behavior when used as a thickener or reinforcing filler.

Minimum orders are typically one drum for liquid materials and pallets for materials that ship in bags. Availability varies. Please call for details.
