Effects of Plasticizers on Extrusion of Dry Blended PVC
-
A. Datta
Abstract
This research was concerned with the effect of two different plasticizers on the plasticating extrusion behavior of polyvinylchloride (PVC). Diisodecyl pthalate (DIDP) and dihexyl pthalate (DHP) were the the two plasticizers used in this study. First some differences in the extrusion performance of the two differently plasticized PVC compounds were identified. In particular, it was observed that pressure build-up and power requirement were affected by the plasticizer type with the DIDP plasticized materials generating higher pressures and requiring more power than the DHP plasticized materials. Also the DIDP plasticized material fused earlier in the screw channel and in general exhibited slightly higher flow rates. The differences in extrusion characteristics were observed for two different dies attached to the extruder.
