Title (EN) FLAME RETARDED STYRENIC POLYMER FOAMS
(FR) MOUSSES A BASE DE POLYMERE DE STYRENE IGNIFUGEES
Abstract: front page image
(EN)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.
(FR)La présente invention a trait à des mousses, notamment des mousses de polystyrène extrudé et de polystyrène expansé, ignifugées au moyen d'un ou de plusieurs additifs de bis(bromoalkyl)bromophtalate ignifugeants, de préférence de bis(2,3-dibromopropyl)tétrabromophtalate. De manière inattendue, la distribution de grains de mousse de polystyrène expansé dans la plage de dimensions commerciales souhaitée s'est accrue par l'utilisation de bis(2,3-dibromopropyl)tétrabromophtalate.
