Title (EN) PROCESS FOR PRODUCING FOAM BEADS USING A MODIFIED ETHYLENE-BASED POLYMER
(FR) PROCÉDÉ DE PRODUCTION DE BILLES DE MOUSSE À L'AIDE D'UN POLYMÈRE À BASE D'ÉTHYLÈNE MODIFIÉ
Abstract:
(EN) The present disclosure provides a process. The process includes (i) forming a composition containing a peroxide-modified ethylene-based polymer selected from the group consisting of a peroxide-modified ethylene/α-olefin multi-block copolymer, a peroxide-modified low density polyethylene, and combinations thereof; (ii) contacting the composition with a blowing agent to form a foam composition; and (iii) forming foam beads comprising the foam composition. The present disclosure also provides a foam bead produced by said process.
(FR) La présente invention concerne un procédé. Le procédé comprend (i) la formation d'une composition contenant un polymère à base d'éthylène modifié par du peroxyde, sélectionné dans le groupe constitué par un copolymère multi-séquencé d'éthylène modifié par du peroxyde/d'α-oléfine, un polyéthylène basse densité modifié par du peroxyde, et des combinaisons correspondantes; (ii) la mise en contact de la composition avec un agent d'expansion pour former une composition de mousse; et (iii) la formation de billes de mousse comprenant la composition de mousse. La présente invention concerne également une bille de mousse produite au moyen dudit procédé.
