Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. 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). 2. The styrene polymer according to claim 1 , which is a styrene homopolymer or a styrene copolymer having up to 40% by weight, based on the weight of the polymer, of at least one further ethylenically unsaturated monomer. 3. The styrene polymer according to claim 1 , wherein the at least one flame retardant is an organic bromine compound. 4. The styrene polymer according to claim 1 , wherein the at least one metal has been selected from the group consisting of iron, copper, molybdenum, zirconium, and mixtures thereof. 5. The styrene polymer according to claim 1 , wherein the at least one flame retardant is hexabromocyclododecane (HBCD). 6. The styrene polymer according to claim 1 , wherein the athermanous particles are graphite. 7. A process for the production of the expandable styrene polymer according to claim 1 , via mixing of the expandable styrene polymer, of the at least one flame retardant as component (A), and of the athermanous particles as component (C), where from 0.0001 to 2% by weight, based on component (A), of at least one metal is present as component (B). 8. 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). 9. A process for the production of 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), the process comprising foaming an expandable styrene polymer according to claim 1 . 10. A foam, capable of production from the expandable styrene polymer according to claim 1 . 11. A process for the production of a foam according to claim 10 , via production of 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) and foaming of this expandable styrene polymer. 12. A thermal insulation, including that of machines and of household devices, or a packaging material comprising the foam according to claim 10 .
