Product Information

CAB-O-SIL M-5 is a medium surface fumed silica that imparts a significant increase in viscosity in liquid systems, free flow of powders, and reinforcement of silicone and organic rubbers.


Increase Viscosity
CAB-O-SIL M-5 is widely used to provide thickening, thixotropic (shear-thinning), and anti-settling behavior in liquid systems. M-5 is most efficient in non-polar to medium polarity systems. For more polar systems, treated fumed silicas are more effective. M-5 offers the best balance of thickening efficiency and dispersibility.


Free-Flow of Powder Systems
When blended into sticky and poorly flowing powder systems, M-5 reduces the angle of repose and improves powder flow. During storage of powder systems, M-5 reduces caking and blocking.


Reinforcement of Silicone and Organic Rubber
CAB-O-SIL M-5 can be used for reinforcement of silicone rubber and can be used to reinforce organic rubbers. It imparts good increase in hardness, tensile, and elongation.
