Gloss Control in Rigid PVC -Part II.Effect of Processing Variables on the Gloss of Rigid PVC Profiles

摘要

This paper describes the results of a study of the effect of extrusion conditions on the gloss of rigid PVC profiles.Extrusion variables investigated are extrusion melt temperature,extruder temperature settings,extrusion rate,and the die/sizer metal surface condition.It is hoped that this information will help PVC profile manufacturers to optimize their process for achieving desirable gloss.
