| abstract |
Thermoplastic material composed of several layers (4) in the form of a hollow body consisting of at least one inner layer (1) based on polyamides, at least one intermediate layer (2), as well as at least one thermoplastic outer layer (3 ), with at least one intermediate layer (2) based on ethylene / vinyl alcohol copolymers (EVOH) being present, and limiting the inner layer (1) directly with the intermediate layer (2), <br /> <br /> characterized because <br /> <br /> the inner layer (1) is formed by a mixture of the two homopolymers of polyamide polyamide 6 and polyamide 12, and contains a compatibilizer, <br /> <br /> limiting the intermediate layer ( 2) directly with the outer layer (3), <br /> <br /> the outer layer (3) being formed by a mixture of the two homopolymers of polyamide polyamide 6 and polyamide 12, and containing a compatibilizer. |
