Title
(EN) A THERMOPLASTIC COMPOSITION HAVING IMPROVED MECHANICAL PROPERTIES
(FR) COMPOSITION THERMOPLASTIQUE À PROPRIÉTÉS MÉCANIQUES AMÉLIORÉES
Abstract
(EN) The invention is directed to a thermoplastic composition comprising a thermoplastic polymer component and at least one elastomer, wherein the thermoplastic polymer component comprises at least one propylene copolymer having a propylene content of at least 60 wt.-% and at least one ethylene copolymer having an ethylene content of at least 50 wt.-%. The invention is also directed to a sealing device comprising a waterproofing layer obtained by using the thermoplastic composition, to a method for producing a sealing device, to a method for waterproofing a substrate, and to a method for bonding a first substrate to a second substrate.
(FR) L'invention concerne une composition thermoplastique comprenant un constituant polymère thermoplastique et au moins un élastomère, le constituant polymère thermoplastique comprenant au moins un copolymère de propylène ayant une teneur en propylène d'au moins 60 % en poids et au moins un copolymère d'éthylène ayant une teneur en éthylène d'au moins 50 % en poids. L'invention concerne également un dispositif d'étanchéité comprenant une couche d'imperméabilisation obtenue au moyen de la composition thermoplastique, un procédé de production d'un dispositif d'étanchéité, un procédé d'imperméabilisation d'un substrat et un procédé de liaison d'un premier substrat à un second substrat.
