Process for the continuous production of granules based on thermoplastic polymers comprising at least one expandable agent and, optionally, other polymers or additives, among which inorganic pigments insoluble in the Polymeric matrix, wherein a first main stream (21) is prepared, in the molten State, and a second stream (22) in the molten State, which englobes the additives (16) and which is added to the first stream. The mixture is extruded through a die (37) which is cooled by means of water jets from nozzles positioned behind the cutting blades.
L'invention concerne un procédé de production continue de granulés à base de polymères thermoplastiques comprenant au moins un agent expansible et, éventuellement, d'autres polymères ou additifs, parmi lesquels, des pigments inorganiques insolubles dans la matrice polymère. dans ce procédé, un premier flux principal (21) est préparé à l'état état fondu, et un second flux (22) est également préparé, à l'état état fondu, lequel le second flux comprenant des additifs (16) et étant ajouté au premier flux, puis ce mélange est extrudé par une matrice (37) qui est refroidie à l'aide de jets d'eau provenant d'ajutages montés derrière des lames de coupe.
