PS FOAMS HAVING LOW METAL CONTENT

摘要

The present invention relates to an expandable styrene polymer, comprising at least one flame retardant as component (A), 0.0001 to 2 wt.%, in relation to component (A), of at least one metal as component (B), and athermanous particles as component (C), to a method for the production of said expandable styrene polymer, to an expanded styrene polymer particle, comprising at least one flame retardant as component (A), 0.0001 to 2 wt.%, in relation to component (A), of at least one metal as component (B), and athermanous particles as component (C), to a method for the production of said expanded styrene polymer particle, to a foam that can be produced from said expandable styrene polymer, to a method for the production of said foam, and to the use of said foam for heat insulation, for the thermal insulation of machines and household appliances, and as a packaging material.
