Abstract: Multilayer structure intended for the transportation, for the distribution and for the storage of hydrogen, including, from the inside toward the outside, at least one leaktightness layer (1) and at least one composite reinforcing layer (2), said innermost composite reinforcing layer being wound around said outermost adjacent leaktightness layer (1), said leaktightness layers having a composition predominantly including: at least one aliphatic polyamide thermoplastic polymer P1i, i=1 to n, n being the number of semicrystalline leaktightness layers, the Tm of which, as measured according to ISO 11357-3: 2013, is greater than 200° C., with the exclusion of a polyether block amide (PEBA), said polyamide thermoplastic polymer being a polyamide exhibiting a mean number of carbon atoms per nitrogen atom of from 7 to 9, up to 30% by weight of impact modifier, up to 1.5% by weight of plasticizer, said composition being devoid of nucleating agent.

Abstract: A composition including: (a) 30% to 99.8% by weight by weight of recycled material from a used single-layer and/or multilayer tube and/or tank having initially transported or contained motor vehicle fluids, the tube and/or the tank having a composition which predominantly includes at least one polyamide, the used tube and/or the used tank having been ground into granules and the fluid residues present in the tube and/or tank having been totally or partially extracted, (b) up to 70% of a semicrystalline aliphatic polyamide, (c) up to 0.2% of an additive, the polyamide of the used tube and/or the used tank having functions resulting from oxidation reactions chosen from the primary amide functions, nitriles, terminal methyl groups, alkenes, formamides, imides, carboxylic acids and alcohols and mixtures thereof, in a mole ratio greater than that of the same polyamide constituting a non-used tube and/or tank which has not yet transported or contained motor vehicle fluids.

Abstract: The present invention relates to a composition for blow-molding or extrusion, in particular blow-molding, comprising by weight: a) from 88 to 99.95%, more particularly from 89 to 99.9%, in particular from 93 to 99.9%, of at least one semicrystalline aliphatic polyamide having a carbon number per nitrogen atom of greater than or equal to 7, more particularly greater than or equal to 8, b) from 0.05% to 10%, more particularly from 0.1% to 9%, in particular from 0.1% to 5% by weight of at least one branching agent chosen from polyepoxides, polyanhydrides and polyisocyanates, more particularly polymaleic anhydrides and polyepoxides, c) from 0 to 2% of at least one additive, more particularly 10 from 0.1 to 2%, the composition having, after compounding, a melt viscosity of from 10 000 to 300 000 Pa·s, preferably from 15 000 to 220 000 Pa·s, as measured in plane-plane geometry according to ISO standard 6721-10:2015 at a temperature of 250° C., a frequency of 0.292 rad/s and a deformation of 2%, the sum of the constituents a)+b)+c) making 100% by weight.
