Abstract

Cette invention se rapporte à des plastiques imitant le granite, qui peuvent servir comme revêtements et dans toutes les formes de techniques de moulage et de thermoformage. Ces plastiques imitant le granite contiennent une multitude de granulés formés par une combinaison de thermoplastique et de plastique thermodurcissable, suspendue à l'intérieur d'une matrice. La matrice peut être constituée soit par un thermogel soit par une résine thermoplastique pouvant contenir des charges additionnelles.
