Abstract
Thermoplastic/elastomer composite product, in particular a hose for transporting a coolant for an automobile air-conditioning circuit, comprising an internal layer formed from a plastic alloy comprising a nylon-6 and at least 51% of a modifier chosen from among ethylene-acrylate-acrylic acid terpolymers and a layer formed from a blend of an elastomer, such as a brominated butyl rubber modified by a grafted 1,2-vinyl polybutadiene, a silane, an ethylene-acrylic acid copolymer or an ethylene-propylene copolymer grafted with maleic anhydride, with complete adhesion between the thermoplastic and the elastomer.
