Title
(EN) METHOD AND FORMULATION FOR RENEWABLE POLYETHYLENE FOAMS
(FR) PROCEDE ET FORMULATION POUR MOUSSES DE POLYETHYLENE RENOUVELABLE
Abstract
(EN) A method of making a foam using a renewable resource and a foam thereof is disclosed. The foam is made using green polyethylene polymers made from renewable sugarcane ethanol. The use of these polymers to make foam has the potential to reduce carbon dioxide gas emissions by more than half. The foam can be used in a variety of applications and can also be made with blends of renewable LDPE and non-renewable LDPE.
(FR) L'invention concerne un procédé de fabrication d'une mousse à l'aide d'une ressource renouvelable et une mousse associée. La mousse est fabriquée à l'aide de polymères de polyéthylène vert produit à partir d'éthanol de canne à sucre renouvelable. L'utilisation de ces polymères pour fabriquer une mousse a le potentiel de réduire les émissions gazeuses de dioxyde de carbone de plus de la moitié. La mousse peut être utilisée dans diverses applications et peut également être préparée avec des mélanges de LDPE renouvelable et de LDPE non renouvelable.
