PURPOSE: A silicon fluid rubber composition is provided to have excellent injection moldability when manufacturing large or complicated products by improving flow. CONSTITUTION: A silicon fluid rubber composition in chemical formula 1 having a mixture viscosity of less than 30 Pa.s, and comprises: an alkenyl radical of 0.001-5mmol/g viscosity in the both ends of polymer or branched chains; linear polyorganosiloxane of 100-150,000,Pa.s viscosity at 25°C; polyorganohydrogensiloxane, which is in chemical formula2, having hydrogen of 0.1-20mmol/g in branched chain; polyorganohydrogensiloxane, which is in chemical formula3, having hydrogen of 0.05-5.0mmol/g in the both ends; a strengthening silica in which the specific surface area is 50m/g or greater; titanium dioxide having over 90% purity; a carbon black on amorphous powder; an azo compound; a platonic compound; and a hardening retarding agent. |
