Title (EN) METHOD FOR PRODUCING STRUCTURAL FOAM AND PRODUCTS CONTAINING STRUCTURAL FOAM
(FR) PROCÉDÉ POUR LA PRODUCTION DE MOUSSE STRUCTURÉE ET PRODUIT CONTENANT DE LA MOUSSE STRUCTURÉE
Abstract:
(EN) The invention provides a method for generating structural foam having a density in the range of 0.4-0.75 gr/cm3. A gas is generated in a plastic melt melt under conditions inhibiting bubble formation in the melt. The melt is injected into a mold and the volume of the mold is varied to produce a structural foam having a density in the specified range. The invention also provides a sheet of structural foam having a density in the range of.4-0.75 gr/cm3 produced by the method of the invention and a panel comprising a sheet of structural foam of the invention. The invention also provides a structure comprising two or more panels according of the invention. The structure may be, for example, a cabinet, cupboard, shed or piece of furniture.
(FR) L'invention porte sur un procédé pour la production de mousse structurée ayant une masse volumique dans l'intervalle de 0,4 à 0,75 g/cm3. Un gaz est produit dans une masse fondue de matière plastique dans des conditions inhibant la formation de bulles dans la masse fondue. La masse fondue est injectée dans un moule et le volume du moule est amené à varier pour produire une mousse structurée ayant une masse volumique dans l'intervalle spécifié. L'invention porte également sur une feuille de mousse structurée ayant une masse volumique dans l'intervalle de 0,4 à 0,75 g/cm3 produite par le procédé de l'invention et sur un panneau comprenant une feuille de mousse structurée de l'invention. L'invention porte également sur une structure comprenant deux ou plus de deux panneaux selon l'invention. La structure peut être, par exemple, un meuble de rangement, un placard, un abri ou un meuble.
