CAB-O-SIL® LM-150 Fumed Silica

CAB-O-SIL® LM-150 by Cabot is a low surface area fumed silica. It imparts a moderate increase in viscosity and reinforcement in liquid and polymer systems. It possesses high purity, aggregated structure, submicron particle size, low bulk density and hydrophilic surface chemistry. It provides the best balance of dispersibility, thixotropy and reinforcement in RTV-1 and RTV-2 silicone sealants. It imparts a moderate increase in hardness, tensile and elongation for the reinforcement in silicone rubbers.
