Abstract
A multi-layer assembly for fluid and vapor handling and containment systems. The multi-layer tubing assembly comprises an extrudable layer of conductive fluoropolymer, a layer of modified fluoropolymer containing a reactive group extruded around the layer of conductive fluoropolymer and a layer of polar polymer extruded around the layer of modified fluoropolymer. The layer of modified fluoropolymer is bonded to the layer of polar polymer.
