Abstract:
The invention relates to a method for producing a tank having high fluid-barrier properties. According to the invention, a specific polyamide composition containing impact-resistance modifying agents is used in a first step to produce components by means of injection moulding and, subsequently, said components are assembled in order to obtain the tank. The viscosity and gasoline permeability of the polyamide composition are sufficient to allow the production of tanks that provide an excellent trade-off between fluid-barrier properties and mechanical properties.
