Abstract

Procédé pour la fabrication d'une structure alvéolaire expansée à base d’une polyoléfine, selon lequel : on mélange une polyoléfine ayant un MFI supérieur à 10 dg/min à un agent d'expansion pour former une composition apte à l'expansion on extrude en continu, des feuilles parallèles de ladite composition à l'intérieur d'une chambre de reftoidissement ayant des compartiments situés de part et d'autre des feuilles on réalise alternativement, dans chaque chambre, une injection de fluide de refroidissement sous pression et une dépression, les deux compartiments situés des deux côtés d'une même feuille étant pour l'un soumis à l'action du fluide sous pression et pour l'autre, àl'action de la dépression, et inversement lors de l'alternance suivante, fin de réaliser la déformation des feuilles et leur soudage deux à deux avec formation d'alvéoles perpendiculaires à la direction d'extrusion.
