Abstract

L'invention concerne une feuille (A) de mousse de polystyrène permettant un thermoformage profond d'articles, et qui comprend 0,5 à 15 % en poids d'un composant caoutchouc, et 0,5 à 2,0 % en poids d'un agent de nucléation. Cette feuille possède une épaisseur uniforme comprise entre 0,060 et 0,250 pouces avec une tolérance de ± 0,10 pouces, une densité comprise entre 4 et 18 livres par pied cube, et une dimension alvéolaire moyenne comprise entre 0,12 et 0,34 mm. Eventuellement, on peut, avant thermoformage, revêtir ou stratifier par extrusion la feuille de mousse d'une ou plusieurs pellicules (22). Les articles ainsi obtenus ont des rapports d'étirage supérieurs à 1,0, une bonne capacité d'isolation thermique et un aspect agréable.
