Title (EN) FOAMED ARTICLES
(FR) ARTICLES EXPANSES
Abstract:
(EN) A foamed article having a closed cell structure formed from: (i) a polymer blend comprising at least 80 % by weight of a styrenic polymer and up to 20 % by weight of an acrylic polymer; and (ii) a gaseous blowing agent such that the thermal conductivity of the foamed article is no more than 97 % of that of a foamed article formed from the styrenic polymer alone.
(FR) Article expansé présentant une structure à cellules fermées constitué de: i) un mélange polymère comprenant au moins 80 % en poids d'un polymère styrénique et jusqu'à 20 % en poids d'un polymère acrylique; et ii) un agent gonflant gazeux, tel que la conductivité thermique de l'article expansé est égale au plus à 97 % de celle d'un article expansé constitué du polymère styrénique uniquement.
