Abstract
A layered tubing for use in a motor vehicle composed of a thick outer layer having an inner and an outer face, the outer layer made of an extrudable thermoplastic elastomer; a thin intermediate bonding layer bonded to the inner face of the thick outer layer, the bonding layer composed of an extrudable melt-processible thermoplastic capable of sufficiently permanent laminar adhesion with the thick outer layer; an interior layer bonded to the intermediate bonding layer, the interior layer composed of a fluoroplastic which is resistant to permeation by and interaction with short-chain aliphatic and aromatic compounds; and an innermost electrostatic dissipation layer.
