Abstract

L'invention concerne l'extrusion de matériaux thermodurcissables et de matériaux thermoplastiques. Le procédé consiste à effectuer l'extrusion d'un matériau en présence de substance abaissant le frottement externe du bain de fusion. Pour un rapport du frottement interne au frottement externe du bain de fusion compris entre 1,5 et 4,0 à une vitesse d'extrusion de 20 à 300 m/mn, la viscosité du bain du matériau thermodurcissable est de 50.10**6 à 300.10** 6 poises alors que l'indice du fusion du matériau thermoplastique est de 0,01 à 0,1 g/10 mn. Application : fabrication de granulés en matériau thermodurcissable.
