Title
(EN) POLYOLEFIN FOAM BEADS AND PROCESS FOR PRODUCING THE SAME
(FR) BILLES DE MOUSSE DE POLYOLÉFINE ET PROCÉDÉ POUR LA PRODUCTION DE CELLES-CI
Abstract
(EN) The present disclosure relates to polyolefin foam beads comprising one or more polyolefin interpolymers, wherein the foam bead has a gel content of higher than or equal to 80% and a tan delta at 1 rad/s of lower or equal to 0.11 and a process for producing the same. The present disclosure further relates to an element prepared from the foam beads, a product comprising the element, and use of the foam beads in bead-filling applications.
(FR) La présente invention concerne des billes de mousse de polyoléfine comprenant un ou plusieurs interpolymères de polyoléfine, la bille de mousse ayant une teneur en gel supérieure ou égale à 80 % et une tangente delta à 1 rad/s inférieure ou égale à 0,11 et un procédé pour la production de celles-ci. La présente invention concerne en outre un élément préparé à partir des billes de mousse, un produit comprenant l'élément et l'utilisation des billes de mousse dans des applications de garnissage par des billes.
