CAB-O-SIL® Grade M5 Untreated Fumed Silica - 10 lb Bag

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.

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.

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.
