In this work, the melt strength of PP matrix was reinforced by crosslinking-modified PP (CM-PP) which was yielded by peroxide-initiated crosslinking of linear PP with butyl acrylate (BA). The nano-silica aerogel (nano-SiO2) worked as a nucleating agent for foaming. The effects of CM-PP with the various contents of BA on the foaming behavior and thermal property of PP were studied by measurements of density, thermal conductivity, Vicat softening temperature and SEM. The results showed that the foamed PP got the best properties when the crosslinking PP modified with the weight ratio of butyl acrylate was 10 wt %. The density of the obtained foamed PP with uniform closed cells was as low as 0.23 g/cm3, the thermal conductivity was 0.044 W/(m K), and the Vicat softening temperature was 120 °C. © 2016 Wiley Periodicals, Inc.
