Abstract
Composite polyether block amide (PEBA) copolymer tubes incorporate an ultra-thin PEBA layer that enables rapid moisture transfer and exchange through the tube. A composite PEBA film may include a porous scaffold support and may be formed or incorporated into the composite PEBA tube. A porous scaffold support may be coated or imbibed with PEBA to form a composite PEBA film. A composite PEBA film may be wrapped on a mandrel or over a porous scaffold support to form a composite PEBA tube. A film layer may be applied over a wrapped composite PEBA film to secure the layers together. The film layer by applied by dipping, spraying or painting.
