Title
(EN) SINGLE-LAYER STRUCTURE BASED ON RECYCLED POLYAMIDE
(FR) STRUCTURE MONOCOUCHE A BASE DE POLYAMIDE RECYCLE
Abstract
(EN) The present invention relates to a single-layer tubular structure intended to convey fluids for a motor vehicle, formed by a layer (1) formed by a composition predominantly comprising at least one catalysed semi-crystalline aliphatic polyamide, the composition being formed by at least 30% by weight, in particular at least 50% by weight, of recycled material originating from at least one single-layer and/or multi-layer tube that was intended to convey fluids for a motor vehicle, the at least one single-layer and/or multi-layer tube being formed by a composition that predominantly comprises at least one catalysed or non-catalysed polyamide, said at least one single-layer and/or multi-layer tube having been crushed, then at least recompounding with or without the addition of at least one catalyst in order to be able to be recycled, a simple one-off crushing being excluded.
(FR) La présente invention concerne une structure tubulaire monocouche destinée au transport de fluides pour automobile, constituée d'une couche (1) constituée d'une composition comprenant majoritairement au moins un polyamide aliphatique semi-cristallin catalysé, ladite composition étant constituée d'au moins 30% en poids, en particulier d'au moins 50% de matière recyclée provenant d'au moins un tube monocouche et/ou multicouche ayant été destiné au transport de fluides pour automobile, ledit au moins un tube monocouche et/ou multicouche étant constitué d'une composition qui comprend majoritairement au moins un polyamide catalysé ou non, ledit au moins un tube monocouche et/ou multicouche ayant subi un broyage puis au moins un recompoundage avec ou sans ajout d'au moins un catalyseur pour pouvoir être recyclé, un simple broyage unique étant exclu.
