Polyester thermal conductivity

WebSep 7, 2024 · Unsaturated polyester resin (UPR)/titanium dioxide (TiO 2) nanocomposites were obtained by the incorporation of TiO 2 nanoparticle surface modified with titanate in the UPR. The mechanical properties, thermal behavior, anti-ultraviolet aging properties and composite microstructure were tested. WebFigure 1 shows the setup used to determine the thermal conductivity of a material by DSC. The heat flow from the sensor to the pure metal depends not only on the thermal resistance of the sample, but also on the thermal resistances at the sensor-sample (R 1) and sample-metal (R 2) interfaces.
