Preparation of Silica Aerogels Modified Foamed Polypropylene for Thermal Insulating Applications

Abstract:

The foamed polypropylene (PP) with excellent thermal insulating property was prepared by using the nanosilica (SiO₂) aerogels as nucleators, followed by mould pressing foam in cross-link. The weight ratio of SiO₂/ PP, which was at the range of 0~ 2%, significantly affected the morphology and thermal insulating properties of the foamed PP. The results showed that the foamed PP can get excellent properties when the weight contents of SiO₂ aerogels was 1 %. The foamed PP with low density as 0.43 g/cm³and thermal conductivities at the range of 0.046~0.507 W.(m.K^-1) was obtained by using this method.
