CAB-O-SIL® M-7D Fumed Silica

CAB-O-SIL® M-7D Fumed Silica by Cabot is a medium-high surface area silica that reinforces silicone rubber. It is the densed form of CAB-O-SIL® M-5 fumed silica. The higher bulk density enables faster incorporation and easier handling. It offers high purity, low bulk density, aggregated structure, hydrophilic surface and submicron particle size. It is suitable for use in the reinforcement of silicone rubbers, including heat-cured rubber, high temperature vulcanizing or high consistency rubber (HTV or HCR) and liquid silicone rubber (LSR). It provides increased hardness, tensile strength and elongation. Due to the hydrophilic surface of CAB-O-SIL® M-7D Fumed Silica further modification of its surface is necessary to prevent crepe hardening.

CAB-O-SIL® MS-75D Fumed Silica

CAB-O-SIL® MS-75D Fumed Silica by Cabot is a medium-high surface area fumed silica that reinforces silicone rubber. It is the densed form of CAB-O-SIL® MS-55. It enables faster incorporation and easier handling. It possesses high purity, low bulk density, aggregated structure, submicron particle size and hydrophilic surface chemistry. It imparts a significant increase in hardness, tensile and elongation. The higher bulk density facilitates faster wet-in or incorporation into viscous polymer systems. CAB-O-SIL® MS-75D Fumed Silica is suitable for use in the reinforcement of silicone rubbers, including heat-cured rubber, high temp vulcanizing or high consistency rubber (HTV or HCR) and liquid silicone rubber (LSR). Due to the hydrophilic surface further modification of its surface is necessary to prevent crepe hardening.
