ABSTRACT:
Described herein is a method of preparing a fluoropolymer composite tube comprising the steps of activating a formed fluoropolymer substrate by subjecting the substrate to a charged gaseous atmosphere formed by electrically ionizing a gas which contacts the substrate and thereafter applying a layer of a thermoplastic polymer to the activated fluoropolymer substrate. The ionizing step can be described as a corona discharge or an electrically formed plasma. In particular, described is a fuel pipe comprised of an inner fluorocarbon layer having electrostatic discharge resistance and hydrocarbon evaporative emission resistance and on top of and integral with, the fluorocarbon layer an outer layer of a thermoplastic polymer. Fluoropolymer layers have excellent chemical resistance.
