In order to look into the internal structure and the properties in the silicone rubbers added reinforcing fillers; silica $additives(O{sim}140phr)$, and to examine the behavior of charged particles, the properties of thermally stimulated current(TSC) and X-Ray diffraction are investigated, respectively. And then, from the TSC which are formed by applying the electric field of $2{sim}5kV/mm$ to specimen at the temperature range from -150 to $260^{circ}C$, the results are as follwing: In the case of non-filled specimen, four peaks of ${delta},;{gamma},;{eta};and;{alpha}$ are obtained at the temperature of $-120^{circ}C,;-60^{circ}C,;20^{circ}C;and;130^{circ}C$, respectively and the case of filled specimen, three peaks of ${delta},;{alpha}_2;and;{alpha}_1$ are observed at the temperature of $-120^{circ}C,;80^{circ}C;and;130^{circ}C$, respectively. The origins of these peaks are that, the ${delta}$ peak seems to the result from the contribution of side chain methyl radical, and the ${gamma}$ peak from the depolarization of space charge polarization owing to be added impurity during manufacturing specimens, and the ${eta}$ peak from the orientation of $Si-CH_3$ dipole, and the ${alpha}_2$ near the temperature of $80^{circ}C$ from hydroxyl in carboxylic radical, and finally, the ${alpha}_1$ peak near the temperature of $130^{circ}C$ from carboxyl acid that is formed by the thermal oxidation of high temperature.
