FLAME RETARDED STYRENIC POLYMER FOAMS

Styrenic polymer foams, especially XPS and EPS, are flame retarded by use of one or more flame retardant bis(bromoalkyl)bromophthalate additives, most preferably bis(2,3-dibromopropyl)tetrabromophthalate. Surprisingly, the distribution of EPS beads in the desired commercial size range was increased...

Zusammenfassung:Styrenic polymer foams, especially XPS and EPS, are flame retarded by use of one or more flame retardant bis(bromoalkyl)bromophthalate additives, most preferably bis(2,3-dibromopropyl)tetrabromophthalate. Surprisingly, the distribution of EPS beads in the desired commercial size range was increased by the use of bis(2,3-dibromopropyl)tetrabromophthalate.
