Abstract

L'invention concerne un appareil pour la coextrusion de polymères à des températures différentes, comprenant au moins deux extrudeuses, lesquelles sont raccordées à une tête d'extrusion qui comporte une zone d'isolation et au moins une zone de refroidissement et une zone de chauffage, un ensemble filière/porte-filière étant montés à la tête d'extrusion. L'invention porte aussi sur un procédé de coextrusion de deux polymères ou plus, à des températures différentes, qui consiste à façonner les polymères séparément les uns des autres, jusqu'à ce qu'il se rejoignent à proximité de la plaque avant de la filière, où les polymères sont mis en contact et un extrudat est formé.
