Abstract
A hose including at least one permeation resistant layer, an elastomeric layer overlaying each at least one permeation resisting layer, at least one reinforcement layer overlaying an elastomeric layer, and a cover layer overlaying the at least one reinforcement layer, wherein the at least one permeation resistant layer includes a plurality of sublayers of at least two different thermoplastics wherein the sublayers have a thickness of less than 2500 nanometers.
Claims9
A hose comprising:
- at least one permeation resistant layer configured to resist the permeation of a refrigerant;
- an elastomeric layer overlaying the at least one permeation resisting layer;
- at least one reinforcement layer overlaying the elastomeric layer;
- and
- a cover layer overlaying the at least one reinforcement layer,
- wherein the at least one permeation resistant layer is comprised of a plurality of sublayers of first and second thermoplastics in a weight ratio ranging from 5:1 to 1:5, the first thermoplastic is a liquid crystal polymer, and each of the sublayers has a thickness of less than 2500 nanometers.
