Title (EN) EXTRUSION AGENT FOR POLYOLEFINS
(FR) AGENT D'EXTRUSION POUR POLYOLEFINES
Abstract:
(EN) The invention relates to the use of a composition as an extrusion agent for the production of an extruded product, wherein: - the extruded product comprises a polyolefin, as well as fillers in a concentration greater than or equal to 15% by weight; - the composition used comprising a fluorinated polymer having a viscosity less than or equal to 15 kP at a temperature of 232 °C and a shear rate of 100 s-1. The invention also relates to an extrusion method for a polyolefin supplemented with fillers, in the presence of such an extrusion agent.
(FR) L'invention concerne l'utilisation d'une composition en tant qu'agent d'extrusion pour la fabrication d'un produit extrudé, dans laquelle: –le produit extrudé comprend une polyoléfine, ainsi que des charges dans une teneur supérieure ou égale à 15 % en poids; –la composition utilisée comprend un polymère fluoré présentant une viscosité inférieure ou égale à 15 kP à une température de 232°C et à un taux de cisaillement de 100 s-1. L'invention concerne aussi un procédé d'extrusion d'une polyoléfine additionnée de charges, en présence d'un tel agent d'extrusion.
