Abstract
La présente invention concerne des articles expansés moulés par rotation ainsi que leur procédé de fabrication. On prépare ces articles en introduisant des agents gonflants dans des micro-pastilles. Ces articles fabriqués selon ce procédé possèdent une structure cellulaire et une uniformité améliorées qui conduisent à des propriétés améliorées et généralement uniformes de l'article, y compris par exemple les valeurs d'isolation et la résistance aux chocs.
