Abstract

A process for the extrusion of rigid PVC profile other than pipe is disclosed in a twin conical screw extruder, equipped with high shear screws. The process comprises extruding a compound specially adapted for the process, the compound comprising a polyvinyl chloride resin with an average particle size of from 130 to about 200 microns, a lubricant system containing no more than about 3.5 parts of one or more lubricants, an organo metal salt, from 0 to less than 0.75 parts of a polymeric processing aid, at least one filler/pigment, and a stabilizer for PVC. The process achieves extrudate surfaces characterized by a smooth, dull finish. The process advantageously operates at high extrusion output rates under the conditions specified.
