Abstract

La présente invention concerne un procédé d'amélioration d'un indice de fluidité à chaud initial d'une composition de recyclat de polyoléfine. Le recyclat de polyoléfine est un mélange de polyoléfine contenant du polypropylène recyclé (PP) et du polyéthylène recyclé (PE) et ledit procédé comprend la formation d'un mélange d'un recyclat de polyoléfine et la soumission du mélange à des conditions de mélange. En particulier, la composition de polyoléfine composée est soumise à un traitement thermique à une température supérieure ou égale à 300 °C. L'article ainsi produit comprenant la composition de recyclat de polyoléfine trouve son application dans des applications légères, l'isolation thermique et acoustique, le blindage électromagnétique, l'ingénierie tissulaire, le nettoyage de déversement d'hydrocarbures, et les matériaux souples et à mémoire de forme.
