Medium surface fumed silica
CAB-O-SIL® M-5 by Cabot is is a medium surface fumed silica. Provides thickening, thixotrophic (shear thinning), and anti-settling behavior in liquid systems. It offers an excellent balance of thickening efficiency and dispersibility and enables a significant increase in viscosity in liquid systems, free flow of powders and reinforcement of silicone and organic rubbers. It imparts increases in hardness, tensile strength and elongation. CAB-O-SIL® M-5 is most efficient in non-polar to medium polarity systems.
