This paper describes various techniques for assessing the gloss of PVC extrudates. It discusses the effect of the incident light angle on measured gloss values and the test sensitivity. It also describes the relationship between surface gloss and extrudate roughness, as analyzed by scanning electron microscopy and optical microscopy. Finally, this paper provides recommendations on the most suitable methods for assessing the gloss of PVC extrudates.
