Abstract :
This work explores the thermal behavior of silicone rubber filled at different concentrations with alumina trihydrate (ATH) and silica. Three particle sizes, 1.5 μm, 5 μm and 10 μm, were employed in the sample preparation. A near-infrared laser was used to heat the samples. The concentration of the filler plays a major role on improving thermal conductivity when compared to particle size. Nevertheless, better thermal conductivity could be distinguished at 5 μm for ATH and 1.5 μm for silica, at all concentrations.
