Notes:
Capillary rheometry was carried out on lubricated suspension PVC resin at a temperature of 180°C and a shear rate range of 1.5 to 350 sec-1 to specify lubrication efficiency. Correction and discussion for the effects of pressure, non-Newtonian behavior and viscous heating were done. An indication that the lubricant is localized in the resin free volume appears from pressure coefficient variation. Corrected capillary rheometry showed to be sensitive for low lubricant concentrations (0.3 to 2 Phr) similar to those used in commercial compounds.
