Abstract (en)
[origin: FR2762610A1] 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.
