Product highlights: CAB-O-SIL LM-150D fumed silica, the densed form of CAB-O-SIL LM-150 fumed silica, is a low surface area fumed silica which provides moderate increase in viscosity and reinforcement of sealants and rubbers. The bulk density of CAB-O-SIL LM-150 fumed silica has been mechanically increased for faster incorporation and ease of handling. All untreated fumed silicas are characterized by: - high purity
- aggregated structure
- submicron particle size
- low bulk density
- hydrophilic surface chemistry
Key applications: CAB-O-SIL LM-150D fumed silica is widely used to provide thixotropy and reinforcement of sealants and reinforcement in silicone rubbers. With use of a densed, higher bulk density, silica such as CAB-O-SIL LM-150D fumed silica, using very high shear dispersion equipment is recommended to achieve adequate dispersion of the silica. The higher bulk density of CAB-O-SIL LM-150D fumed silica facilitates faster wet-in or incorporation into these viscous polymer systems.Information provided by Cabot Corporation |
