Title
(EN) IMPROVED EXPANDABLE VINYL AROMATIC POLYMERS
(FR) POLYMÈRES AROMATIQUES DE VINYLE EXPANSIBLES AMÉLIORÉS
Abstract
(EN) The present invention is related to expandable vinyl aromatic polymers comprising comminuted coke, said comminuted coke having an average stack height (Lc) of carbon crystallites less than 4 nm, a volume median particle diameter (D50) comprised between 0.8 and 4 µm and being characterized by a span (D90 – D10)/D50 below 2.5. Molded parts produced from the expandable vinyl aromatic polymers prove low thermal conductivities for a low foam density.
(FR) La présente invention concerne des polymères aromatiques de vinyle expansibles comprenant du coke broyé, ledit coke broyé ayant une hauteur moyenne d'empilement (Lc) de cristallites de carbone inférieure à 4 nm, un diamètre médian de particule en volume (D50) compris entre 0,8 et 4 µm et est caractérisé par un span (D90-D10)/D50 inférieur à 2,5. Les pièces moulées produites à partir des polymères aromatiques de vinyle expansibles selon l'invention présentent de faibles conductivités thermiques pour une mousse basse densité.
