Notes:
A small scale screw extruder designed for laboratory extrusion studies has been developed and its performance characteristics with powder-blended rigid PVC Compounds have been investigated.The use of the extruder in determining the susceptibility of rigid PVC compounds to various die-induced viscoelastic phenomena (fracture, sharkskin, and swell) is described.An investigation of the phenomenon of “nerve” in rigid PVC extrusions has been carried out. It is concluded that nerve is associated with instabilities in the fluxing process occurring in the transition section of the extruder screw design, the operating variables of the process, and the processing characteristics of the compound.
