摘要： Methods related to coextrusion of heat-sensitive polymer materials. The sensitive melt stream element (12) is encapsulated in a second polymeric melt stream element (16). Transport means (36) is preferably employed between the encapsulating means (20) and the die (42). A third melt stream element (68) is joined to one or both opposing surfaces (70) of the second melt stream element (16) between the encapsulating means (20) and the die (42). In the die (42) the encapsulated melt stream element (12) becomes an interior layer (46) between encapsulating layers (48A, 48B) derived from the second melt stream element (16). The third melt stream element (68) forms layers (72, 74) positioned outwardly of the encapsulating layers (48A, 48B). The positioning, on the interior of the extrudate, of edges (54) of layer (46) is adjusted independently of the combined thicknesses of a layer derived from the third melt stream element (68) and an adjacent layer (48).

摘要： The present invention discloses an extrusion die module having a flat compression seal surrounded by a conical or otherwise angled spillover surface. The die module promotes a flat surface to flat surface compression seal outside of the flow distribution channels and promotes better streamlined flow and material combination than a traditional flat disk die module. The die module promotes a reduced overall diameter and wetted diameter in comparison to standard flat disk dies. In addition, the present invention relates to an extrusion die module having a spillover surface surrounding a planar sealing surface. Further, the present invention relates to a method for utilizing an extrusion die module with a conical or otherwise angled spillover surface to minimize the die surface area wetted by an intermediate layer in a multi-layer coextrusion process.
