APPARATUS AND METHOD OF EXTRUSION

摘要

Apparatus and method are provided in a system for continuously feeding disparate materials into a compounding extruder for the inline sheet extrusion of a highly filled thermoplastic material having at least about 65 percent by weight of filler. The apparatus and method of the present invention are particularly suitable in conjunction with the continuous lamination of the inline sheet extruder product with carpet, and involve the steps of continuously feeding disparate materials to a powered extrusion means of the twin screw compounding type, wherein the extrusion means form a blend consisting essentially of a highly filled thermoplastic polymeric material having at least about 65 weight percent filler and an effective amount of processing oil, compounding the disparate materials into a homogeneous melt, and extruding the melt through a sheeting die to form an integral material.
