발명의 명칭: (EN) POLYAMIDE COMPOSITION FOR A METHOD FOR MAKING ARTICLES BY EXTRUSION BLOW-MOULDING AND RESULTING ARTICLES
(FR) COMPOSITION POLYAMIDE POUR PROCEDE DE FABRICATION D'ARTICLES PAR EXTRUSION-SOUFFLAGE ET ARTICLES OBTENUS
요약서:
(EN) The invention concerns a polyamide composition with rheological properties in molten state compatible with a method for shaping by extrusion blow-moulding and improved flexibility for instance, at low temperature. The composition comprises a polyamide thermoplastic polymer based matrix and at least an agent modifying impact strength present at a ponderal concentration between 10 and 50 % of the composition, said composition modulus being less than 1500 MPa's. The invention also concerns an article in the form of a tube comprising a first part (1) obtained by extrusion blow-moulding of a rigid polyamide, a second part (2) likewise obtained by extrusion blow-moulding of a rigid polyamide composition, and an intermediate third part (3) in the form of bellows produced by extrusion blow-moulding of a polyamide composition corresponding to example 1. The extrusion of each part is carried out successively.
(FR) L'invention concerne une composition à base de polyamide présentant des propriétés rhéologiques à l'état fondu compatibles avec un procédé de mise en forme par extrusion-soufflage et une flexibilité améliorée par exemple, à basse température. La composition de l'invention comprend une matrice à base d'un polymère thermoplastique polyamide et au moins un agent modificateur de la résistance aux chocs présent à une concentration pondérale comprise entre 10 et 50 % de la composition, le module de ladite composition étant inférieur à 1500 MPa. Elle concerne également un article sous forme d'un tube comprenant une première partie (1) obtenue par extrusion-soufflage d'un polyamide rigide, une seconde partie (2) également obtenue par extrusion-soufflage d'une composition de polyamide rigide, et une troisième partie (3) intermédiaire en forme de soufflet réalisée par extrusion-soufflage d'une composition polyamide conforme à l'exemple 1. L'extrusion de chaque partie est réalisée de manière séquentielle.
