CAB-O-SIL® M-5 untreated fumed silica is a synthetic,
amorphous, colloidal silicon dioxide that is generally
regarded as unique in industry because of its unusual
particle characteristics. CAB-O-SIL® fumed silica’s extremely
small particle size, its enormous surface area, its high
purity, and its chain-forming tendencies set it apart in a
class of its own. CAB-O-SIL® fumed silica is a light, fluffy
powder that is white in appearance and is used in many
applications and in a variety of industries.
