Abstract

Official abstract text for this publication.

The present disclosure generally relates to extrusion die systems. In particular, the present disclosure relates to the cyclical extrusion of materials to generate small sized grain features, generally in the range of nanosized grain features, in a tubular or profile shape, in which the individual nanolayers possess pores and/or polymer crystals oriented parallel to the extrusion flow direction and including products with enhanced permeation properties.

First claim

Opening claim text (preview).

What is claimed is: 1. A transport device comprising an extruded product with 2-10,000 micro or nano-polymer layers in tubular or profile shapes, wherein the extruded polymer or a component of the polymer comprise lamellar crystals aligned along the axis of extrusion. 2. The transport device according to claim 1 , where the transport device transports water. 3. The transport device according to claim 1 , wherein the transport device transports alcohol. 4. The transport device according to claim 1 , wherein the transport device transports hydrocarbons. 5. The transport device according to claim 1 , wherein the transport device transports blood. 6. The transport device according to claim 1 , wherein the extruded product includes PET. 7. The transport device according to claim 1 , wherein the extruded product includes EVOH. 8. The transport device according to claim 1 , wherein the extruded product includes PA. 9. The transport device according to claim 1 , wherein the extruded product includes PEO.
