Abstract
Ces compositions de poudre qui sont fluides lorsqu'on les soumet à une agitation ou ventilation mécanique, se déposent sous la forme d'un solide compacté lorsque cesse cette agitation/ventilation. Lorsqu'on les soumet à une ventilation, ces compositions ne forment sensiblement pas de bouchons en se fluidisant, et ne présentent sensiblement pas d'effet de canalisation et ni de turbulences. De manière typique, ces compositions sont des compositions pour toner, comprenant un matériau thermoplastique synthétique particulaire comportant au moins un oxyde métallique réfractaire.
