Title (EN) PROCESS FOR PREPARING A POLYOLEFIN COMPOSITION
(FR) PROCÉDÉ DE PRÉPARATION D'UNE COMPOSITION DE POLYOLÉFINE
Abstract:
(EN) A process for preparing a polyolefin composition comprising supplying a bimodal or multimodal polyolefin in form of a polyolefin powder having a mass-median-diameter D50 in the range from 300 μm to 2500 μm and one or more additives to a mixing device, mixing the polyolefin powder and the additives at a temperature from 10°C to 120°C, transferring the mixture into an extruder device, melting and homogenizing the mixture within the extruder device to form a molten polyolefin composition, and pelletizing the molten polyolefin composition, wherein one of the additives is an organic peroxide.
(FR) L'invention concerne un procédé de préparation d'une composition de polyoléfine, comprenant les étapes consistant à fournir à un dispositif mélangeur, une polyoléfine bimodale ou multimodale se présentant sous la forme d'une poudre de polyoléfine bimodale ou multimodale possédant un diamètre moyen en masse D50 dans la plage de 300 µm à 2500 µm et un ou plusieurs additifs, à mélanger la poudre de polyoléfine et les additifs à une température de 10 °C à 120 °C, à transférer le mélange dans un dispositif extrudeur, à faire fondre et à homogénéiser le mélange au sein du dispositif extrudeur en vue de former une composition de polyoléfine fondue, et à transformer en granulés la composition de polyoléfine fondue, un des additifs étant un peroxyde organique.
