Abstract

L'invention concerne des articles moulés en mousse de polymère ayant une nouvelle structure de mousse. Les articles en mousse de polymère comprennent une matrice polymère continue qui définit une pluralité de pneumatocèles dans celle-ci, laquelle est présente dans la totalité de l'article. La région de surface est en outre caractérisée en ce qu'elle comprend des pneumatocèles comprimées. La nouvelle structure de mousse est obtenue même lors du moulage d'articles en mousse de polymère ayant une forme et un volume dans lesquels une sphère ayant un diamètre compris entre 2 cm et 1000 cm peut être insérée dans l'article à au moins un endroit sans dépasser de la surface de l'article, et l'article présente en outre un volume total supérieur à 1000 cm3. L'invention concerne également des procédés de fabrication d'une mousse de polymère fondue stabilisée, et de fabrication d'un article moulé en mousse de polymère en utilisant la mousse polymère fondue stabilisée.
