摘要
Expandable particle composite material suitable for the preparation of expanded materials having a density lower than 40 g/l and a content of closed cells of at least 60%, including heterophase cavities and/or heterophase domains, whose matrix is a synthetic thermoplastic resin having at least 60% by weight of a vinyl aromatic polymer and in which an expanding system is contained, together with a heterogeneously distributed graphite material, having a graphitization degree, calculated by means of the Maire and Mering formula, of at least 0.2.
