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. All untreated fumed silicas are characterized by: - high purity
- aggregated structure
- submicron particle size
- low bulk density
- hydrophilic surface chemistry
Application Information:
Rheology Control for Coatings, Adhesive and other Liquid Systems: 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.
Free-flow of Powder Systems: When blended into sticky and poorly flowing powder systems, CAB-O-SIL M-5 fumed silica reduces the angle of repose and improves powder flow. During storage of powder systems, CAB-O-SIL M-5 fumed silica can reduce caking and blocking.
Reinforcement of Silicone and Organic Rubber: CAB-O-SIL M-5 fumed silica can be used for reinforcement of silicone and organic rubbers. It imparts increases in hardness, tensile strength and elongation.Information provided by Cabot Corporation |
