APPARATUS AND METHOD FOR CO-EXTRUSION OF ARTICLES HAVING DISCONTINUOUS PHASE INCLUSIONS |
摘要 |
The present disclosure provides an apparatus and methods for producing co-extruded composite webs including a continuous layer of an extruded matrix material, and a multiplicity of included phases embedded in the continuous layer. The included phases are surrounded by the matrix material to form a single-layer composite web within a feed block having an internal die body. The included phases are separate from each other by being discontinuous in the cross-web direction, but the included phases may be substantially continuous in the down-web direction. In some exemplary embodiments, the co-extruded single-layer composite web may be used in a single-layer or multi-layer article. In other exemplary embodiments, the single-layer co-extruded composite web may be in the form of a sheet, a film, a blown film, a filament, a fiber, a tube, and the like. |
