Title (EN) EXPANDABLE COMPOSITIONS CONTAINING AROMATIC VINYL POLYMERS HAVING SELF-EXTINGUISHING PROPERTIES AND IMPROVED PROCESSABILITY
(FR) COMPOSITIONS EXPANSIBLES CONTENANT DES POLYMÈRES AROMATIQUES DE VINYLE PRÉSENTANT DES PROPRIÉTÉS D'AUTO-EXTINCTION ET UNE APTITUDE AMÉLIORÉE AU TRAITEMENT
Abstract:
(EN) The present invention relates to an expandable polymeric composition comprising: a) a polymeric matrix containing vinyl aromatic polymers and/or copolymers; b) from 0.1 % to 20% by weight, calculated on the polymeric matrix (a), of an athermanous agent; c) from 0.01% to 10% by weight, calculated on the polymeric matrix (a), of at least one non-polymeric brominated flame retardant additive; d) from 0.01 % to 10% by weight, calculated on the polymeric matrix (a), of at least one brominated polymer containing at least 50% bromine; e) from 0.01 % to 5% by weight, calculated on the polymeric matrix (a), of a synergistic flame retardant additive; f) from 1 % by weight to 10% by weight of at least one blowing agent.
(FR) La présente invention concerne une composition polymère expansible comprenant : a) une matrice polymère contenant des polymères et/ou des copolymères aromatiques de vinyle ; b) 0,1 % à 20 % en poids, calculés par rapport à la matrice polymère (a), d'un agent athermane ; c) 0,01 % à 10 % en poids, calculés par rapport à la matrice polymère (a), d'au moins un additif ignifuge bromé non polymère ; d) 0,01 % à 10 % en poids, calculés par rapport à la matrice polymère (a), d'au moins un polymère bromé contenant au moins 50 % de brome ; e) 0,01 % à 5 % en poids, calculés par rapport à la matrice polymère (a), d'un additif ignifuge synergique ; f) 1 % en poids à 10 % en poids d'au moins un agent d'expansion.
