Process for manufacturing parts having the appearance of natural stones from a composition consisting of a coloured or uncoloured matrix of thermoplastic resin and, per 100 parts by volume of this matrix, 0.2 to 80 parts by volume of at least two fillers chosen from among natural fibres, carbon fibres and mineral or vegetable fillers having different grain sizes or dimensions. By selecting the colour of the matrix and the number, proportion, grain size and colour of the various fillers it is possible to imitate the general appearance and colours of natural stone. The parts obtained after shaping can be used for their esthetic qualities, in particular in packaging cosmetics.
Procédé de fabrication de pièces ayant un aspect de pierres naturelles à partir d'une composition comprenant une matrice colorée ou non en résine thermoplastique et, pour 100 parties en volume de cette matrice, 0,2 à 80 parties en volume d'au moins deux charges choisies parmi les fibres naturelles, les fibres de carbone et les charges minérales ou végétales ayant une granulométrie ou des dimensions différentes. En choisissant la couleur de la matrice et le nombre, la proportion, la granulométrie et la couleur des différentes charges, on peut imiter l'aspect général et les teintes d'une pierre naturelle. Les pièces obtenues après mise en forme sont utilisables pour leur aspect esthétique, notamment dans des conditionnements de produits cosmétiques.
