Abstract
The present invention relates to a composition for manufacturing a three-dimensional object for the transport, distribution, or storage of gases by extrusion blow molding, comprising from 70 to 99.49% by weight of at least one polyamide having a carbon-to-nitrogen ratio greater than or equal to 6.5; from 0.50% to 25% of at least one functional polyolefin having a glass transition temperature (Tg) below -25°C; and from 0.01 to 5% by weight of at least one additive. The composition has a melt viscosity greater than 40,000 Pa·s. The present invention also relates to a method for preparing the composition and the use of the composition to manufacture a three-dimensional object. The present invention further relates to a method for preparing the three-dimensional object.The present invention also relates to the three-dimensional object manufactured by extrusion blow molding as well as the three-dimensional object comprising a sealing layer.
