Properties and Testing


To achieve optimal properties, PVC products need to marry proper formulation design, blending, and melt processing. Discussions will focus on morphological changes that occur in the PVC resin grain and their overall impact on the development of PVC properties during melt processing. Using common tests, we show how these changes influence the development of PVC properties giving the attendee ideas about how the various parts of the product production cycle impacts the finished product and how this combination often exceeds the contribution of any one process or ingredient.

Additionally the presentation will discuss common test methods used in the industry.
