CAB-O-SIL is currently backordered with no ETA. If needed immediately, please call to check our current stock. Large orders may not be able to be fulfilled in a single shipment. We do apologize for any inconvenience.
CAB-O-SIL® M-5 is a medium surface fumed silica that imparts significant increase in viscosity in liquid systems, free flow of powders, and reinforcement of silicone and organic rubbers.
CAB-O-SIL M-5 is widely used to provide thickening, thixotrophic (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 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.
