Title
(EN) POLYMER COMPOSITION FOR IMPROVED GRADE PLASTICS FROM RECYCLED MATERIAL
(FR) COMPOSITION POLYMÈRE POUR PLASTIQUES DE QUALITÉ AMÉLIORÉE À PARTIR DE MATÉRIAU RECYCLÉ
Abstract
(EN)
A polymer composition comprising: a. 60-80 wt% of a recycled polypropylene; b. 10-35 wt% of a recycled polyethylene; c. 5-20 wt% of a polyolefin elastomer (POE); d. 0.1-10 wt% styrene ethylene butylene styrene block copolymer (SEBS); wherein the wt% is relative to the total weight of the polymer composition; wherein said polymer composition comprises at least 11 wt% of polyolefin elastomer and styrene ethylene butylene styrene block copolymer.
(FR)
Une composition polymère comprenant : a. 60-80% en poids d'un polypropylène recyclé; b. 10-35% en poids d'un polyéthylène recyclé; c. 5-20% en poids d'un élastomère de polyoléfine (POE); d. 0,1-10% en poids de copolymère séquencé de styrène-éthylène butylène styrène (SEBS); le pourcentage en poids étant par rapport au poids total de la composition de polymère; ladite composition de polymère comprenant au moins 11% en poids d'élastomère de polyoléfine et de copolymère séquencé de styrène-éthylène-butylène-styrène.
