Abstract

L'invention est relative à des objets moulés à base de cellulose hydratée, caractérisés en ce qu'ils sont essentiellement formés de cellulose hydratée, d'esters assurant une plastification permanente à base de composés organiques dont la molécule contient au moins deux groupes alcooliques dont au moins un est estérifié par un acide monocarboxylique aliphatique de préférence saturé contenant de 9 à 24, de préférence de 16 à 18 et en particulier 17 atomes de carbone, ou de mélanges d'esters de ce genre, ainsi que d'eau et éventuellement de plastifiant chimique secondaire. L'invention concerne également un procédé pour la fabrication de ces objets.
