Thermal insulation improvement of polypropylene using silica aerogel nanoporous

Silica aerogel nanoporous can be used as thermal insulation material in specific applications. Polypropylene(PP) is used widely in many applications at high capacity. However in some industrial applications it is required toimprove thermal stability. The purpose of this study is to improve thermal insulation of polypropylene (PP) by addingaerogels. Silica aerogel nanoporous was used for improving the thermal insulation of polymers. In this study, PP/silicaaerogel composites were prepared and their thermal properties were studied. PP/silica aerogel composites were preparedvia melt compounding method using an internal mixer. The SEM images confirm the homogenous mixing of thecomponents. The measurement of thermal conductivity of samples indicated that adding only 5% of silica aerogel (SA)can increase considerably the thermal insulation of PP.
