ABSTRACT:
Disclosed is a process for manufacturing a conductive fiber-PVC composite which exhibits less than 10.sup.12 hms/sq. resistivity. The process entails incorporating into rigid PVC under heat and shear, a composite of parallel, conductive long fibers embedded in a PVC-dispersible matrix. The process is conducted under the same melt process conditions encountered in the compound processing of rigid PVC, and the long conductive fibers are incorporated a long fiber composite of substantially parallel fibers embedded in a PVC dispersible matrix. The pellets comprise from about 20% to 80% by weight of conductive fiber and 80% to 20% PVC-dispersible thermoplastic.
