20140308506 | Extrudable Polymer Composites With Membrane Barrier Properties - 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. | 10-16-2014 |
20140242310 | Extrudable Oriented Polymer Composites - A novel tubular or profile shapes of co-extruded multilayer polymers. These materials contain tens to thousands of layers of micro- to nano-polymer layers. These new shapes contain contiguous layers of milli- to nano-polymer layers in three dimensions and these contiguous layers may be twisted or turned to further expand the potential microlayer geometries. | 08-28-2014 |
20140141053 | MICROLAYER COEXTRUSION TO CREATE A TIME-RELEASE DRUG SUBSTANCE DELIVERY PRODUCT - The present invention relates to medical devices containing time-release drug substance, and more particularly, to medical tubing, catheters, stents, cables (including fiber optic cables), pills, capsules, sheaths, threads, clamps, sutures, and endotracheal devices. The invention also generally relates to a method for extruding multiple laminated flow streams using microlayer coextrusion to create these various time-release drug delivery products. | 05-22-2014 |
20140056566 | Microlayer Coextrusion of Optical End Products - The disclosed embodiments generally relate to extruding multiple layers of micro- to nano-polymer layers in a tubular shape. In particular, the aspects of the disclosed embodiments are directed to a method for producing a Bragg reflector comprising co-extrusion of micro- to nano-polymer layers in a tubular shape. | 02-27-2014 |
20140034355 | MICROLAYER COEXTRUSION OF ELECTRICAL END PRODUCTS - The present invention including the disclosed embodiments thereof generally relate to extruding multiple laminated flow streams using microlayer extrusion, and in particular to creating and forming products with electrical properties that are formed from layers and particles with dimensions in the micro to nanometer range. | 02-06-2014 |
20120189789 | METHOD AND APPARATUS FOR FORMING HIGH STRENGTH PRODUCTS - A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the non-rotating extrusion system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are compressed, divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a combined laminated output with nano-sized features. The die exit is formed to provide a tubular shape. | 07-26-2012 |
20080315449 | METHOD AND APPARATUS FOR FORMING HIGH STRENGTH PRODUCTS - A system and method are presented in which a flow of plastic is extruded to obtain nano-sized features by forming multiple laminated flow streams, flowing in parallel through the system. Each of the parallel laminated flow streams are subjected to repeated steps in which the flows are divided, and overlapped to amplify the number of laminations. The parallel amplified laminated flows are rejoined to form a cumulated laminated output with nano-sized features. | 12-25-2008 |
