CABOT CAB-O-SIL M-5 FUMED SILICA – CAB-O-SIL M-5 fumed silica is widely used to provide thickening, thixotrophic (shear thinning), and anti-settling behavior in liquid systems. CAB-O-SIL M-5 fumed silica is most efficient in non-polar to medium polarity systems. For more
polar systems, treated fumed silicas are more effective. This product offers an excellent balance of thickening efficiency and dispersibility. CAB-O-SIL M-5 fumed silica is a medium surface fumed silica which enables a significant increase in viscosity in liquid systems, free flow of powders and reinforcement of silicone and organic rubbers. Product is sold by the 10lb. bag.
All untreated fumed silicas are characterized by:
- High purity
- Aggregated structure
- Submicron particle size
- Low bulk density
- Hydrophilic surface
