Definitions

  • the proportion by weight of polyamide polyolefin (polyethylene or polypropylene) will be 70/30 for the reasons explained below. Its thickness will be of the order of 0.4 - 0.5 mm.
  • the third layer according to the invention is a structural layer forming, so to speak, the mechanical reinforcement of the tube according to the invention. It is formed by a polyamide, for example a PA6 comprising an agent modifying impact resistance in a weight concentration of the order of 10 to 50% of the composition.
  • This layer naturally adheres to the layer which is adjacent to it, that is to say the layer of EVOH by the very fact that it comprises a polyamide.
  • We will choose its thickness at least equal to 0.3 mm and preferably between 0.3 to 0.6 mm.
  • a last layer is applied to this reinforcing layer: this last layer is formed from a polyamide modified to resist zinc chloride.
