Definitions
- the inner layer 14 may have a thickness sufficient to supply strength and chemical resistance properties to the multi-layer tubing. Specifically, the inner layer 14 is of sufficient thickness to impede per eation of aliphatic and aromatic hydrocarbon molecules and migration of those molecules through to the thick outer layer. In the present invention, the inner layer has a wall thickness less than that of the thick outer layer. In the preferred embodiment, the inner layer has a wall thickness between about 40% and 60% that of the outer layer; between about 0.05 mm and about 0.2 mm; with a wall thickness between about 0.05 mm and about 0.17 mm being preferred.
- the inner layer 14 may also, optionally, contain suitable material in sufficient quantities to impart electrostatic conductivity characteristics to the tubing of the present invention.
- the interior bonding layer 16 is a chemically dissimilar, permeation resistant, chemical resistant, fuel resistant thermoplastic material which is melt processible in normal ranges of extrusion, i.e. about 175° to about 250°C.
- the material of choice has an elongation value greater than about 150% with an elongation value between about 150% and about 250% being preferred.
- chemically dissimilar it is meant that the intermediate bonding layer 16 is a non-polyamide material which is capable of integral adhesion with and between the thick outer layer 12 and the inner layer 14 as a result of co-extrusion.
- the thermoplastic material which comprises the interior bonding layer 16 is a thermoplastic polyester derived from ethylene glycol selected from the group consisting of polybutylene terepthalate, polyethylene terepthalate, polytere ethylene terepthalate, co-polymers of substituted or unsubstituted alkenes having less than four carbon atoms and vinyl alcohol, alkenes having less than four carbon atoms and vinyl acetate, and mixtures thereof.
- the preferred material is selected from the group consisting of polybutylene terepthalate and copoly ers of ethylene and vinyl alcohol having an ethylene content between about 27% and about 35% by weight.
- carbon-containing materials such as carbon black may be subject to carbon co-polymerization with the surrounding thermoplastic material.
- Materials such as stainless steel are more likely to be interstitially integrated into the crystalline structure of the polymer.
- the intermediate bonding layer can be thinner than the other two layers and can constitute between about 10% and about 50% of the total wall thickness or between about 20% and about 30% of the thickness of the outer layer.
- the thickness of the intermediate bonding layer is between about 0.05 mm and about 0.2 mm with a thickness between about 0.05 mm and about 0.2 mm being preferred.
