摘要： A layered tubing (10) for use in a motor vehicle composed of a thick outer tubing (12) having an inner and an outer face, the outer tubing (12) made of an extrudable thermoplastic such as a polyamide like Nylon 12: a thin intermediate bonding layer (16) bonded to the inner face of the thick outer layer (12), the bonding layer (16) composed of an extrudable melt-processible thermoplastic capable of sufficiently permanent laminar adhesion to the polyamide outer tubing (12); and an inner hydrocarbon barrier layer (14) bonded to the intermediate bonding layer (16), the inner layer (14) composed of an extrudable, melt processible thermoplastic capable of sufficiently permanent laminar adhesion with the intermediate bonding layer (16), the thermoplastic containing as a major constituent a fluoroplastic such as polychlorotrifluoroethylene, ethylene tetrafluorethylene, polyvinylidine fluoride, polyvinyl fluoride, and the like.

摘要： An elongated multi-layer tubing (10) is disclosed for connection to a motor vehicle system to handle fluids containing hydrocarbons. The tubing includes a first layer (14) disposed radially innermost and having an inner surface capable of prolonged exposure to a fluid containing hydrocarbons and an outer surface spaced a first predetermined radial thickness from the inner surface, the first layer (14) consisting essentially of an extrudable, melt-processible thermoplastic. The tubing (10) also includes a second layer (16) having a second predetermined radial thickness at most equal to the thickness of the first layer (14). The second layer (16) is uniformly and homogeneously connected to or bonded to the first layer (14) and consists essentially of an extrudable, melt-processible thermoplastic capable of sufficiently permanent laminar adhesion with the first layer (14) to prevent delamination during a desired lifetime of the tubing. At least one of the first and second layers (14, 16) is resistant to permeation by hydrocarbons. The tubing (10) includes a third layer (12) having a third predetermined radial thickness greater than the thickness of the first layer (14). The third layer (12) is capable of sufficiently permanent laminar adhesion to the second layer (16) to prevent delamination during said desired lifetime of said tubing. The third layer (12) is uniformly and homogeneously connected to or bonded to the second layer (16) and consists essentially of an extrudable, melt-processible thermoplastic. At least one layer of the tubing (10) is capable of dissipating electrostatic energy in a range between about 10?-4 to 10-9 Ohm/cm2¿.
