Abstract
An elongated multi-layer tubing for connection to a motor vehicle system to handle fluids containing hydrocarbons. The tubing comprises an inner layer disposed radially innermost and having an inner surface capable of prolonged exposure to a fluid containing hydrocarbons, the inner layer formed from an extrudable, melt-processible thermoplastic, such as Nylon 12. An outer jacket layer is formed from an extrudable, melt-processible thermoplastic, such as a thermoplastic elastomer (TPE). The tubing further comprises an anhydride-modified, linear low-density polyethylene intermediate layer extruded between the inner and outer layers, the intermediate layer sufficiently adhering the inner layer to the outer jacket to substantially prevent slipping therebetween. At least one of the inner and intermediate layers is resistant to permeation by hydrocarbons. At least one layer of the tubing is capable of dissipating electrostatic energy in a range of 10,to 10,Ohm/cm,.
