Silicone/titanium dioxide (TiO2) composite sheets were prepared from TiO2 particles and silicone elastomer by a compression-molding process at 140 °C. The particles were produced through sol-gel method, and emulsion technique consecutively. The prepared composite sheets with thickness of 0.8 mm had ultraviolet radiation protection property such that the transmission of ultraviolet (UV) B ray through the sheets was less than 1%. The UVA ray transmitted the sheets in the range of 0.02–4% at 320 nm and 2–43% at 400 nm, depending on the amount of TiO2 emulsion presented in the silicone elastomer. The composite sheets still remained transparent since the transmission of the visible light through the sheets was up to 60%. On the other hand, the transmissions of UVB ray, UVA ray, and visible light through the pure silicone elastomer sheets were in the range of 47–58%, 58–71%, and 71–88%, respectively. Comparable with silicone elastomer sheets, the addition of TiO2 emulsion resulted in the composite sheets with higher strain and lower modulus; however, these differences in tensile properties were up to the amount of the emulsion in the silicone elastomer.
