Abstract: L'invention concerne le domaine des matériaux isolants, et en particulier des plaques en liège. Afin de s'affranchir de la fabrication traditionnelle, par compression, d'une plaque de liège tout en proposant un panneau rigide composé essentiellement de liège ayant toutes les propriétés du liège expansé ou naturel, la présente invention propose une plaque composite rigide comprenant des grains de liège seulement agglomérés par un liant et enrobant une armature rigide ajourée, ainsi qu'une méthode pour fabriquer une telle plaque.

Abstract: A method for manufacturing a closure constructed for being inserted and securely retained in a portal-forming neck of a product-retaining container is provided. Such method may include intimately combining a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including one or more thermoplastic polymers, optionally in combination with other constituent(s) to form a composition, heating the composition to form a melt, extruding or molding a closure precursor from the melt to provide a specified water content range, and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure for a product-retaining container includes a plurality of particles comprising cork and having a specified particle size distribution with a plastic material including at least one thermoplastic polymer, optionally with other constituent(s). A closure produced from the composition and use of a closure are also provided.
