Abstract
The present invention relates to an expandable styrene polymer, comprising at least one flame retardant as component (A), from 0.0001 to 2% by weight, based on component (A), of at least one metal as component (B), and athermanous particles as component (C), to a process for the production of this expandable styrene polymer, to an expanded styrene polymer bead, comprising at least one flame retardant as component (A), from 0.0001 to 2% by weight, based on component (A), of at least one metal as component (B), and athermanous particles as component (C), to a process for the production of this expanded styrene polymer bead, to a foam, capable of production from this expandable styrene polymer, to a process for the production of this foam, and also to the use of this foam for thermal insulation, including that of machines and of household devices, and as packaging material.
