Elongated fuel and vapor tube having multiple layers and method of making the same

摘要

An elongated fuel and vapor tube (10) suitable for conveying fluids containing hydrocarbons having a first layer (12) disposed radially innermost and having an inner surface capable of prolonged exposure to the hydrocarbon-containing fluid made up of a melt processible terpolymer composed of a fluorinated alkylene, an alpha-fluoro-olefin and a fluorinated vinyl compound and a second layer (14) bonded directly to the outwardly oriented face of the first layer. The second layer is composed of a melt processible thermoplastic material which is preferably a polyamide.
