Two Component Injection Molding of Phase Separating Blends
-
B. J. Keestra
Abstract
A partially miscible polymer PMMA/SAN blend is used in two component injection molding to produce a sandwich structure with a heterogeneous skin layer. Two different strategies are explored to obtain the desired structure either via sequential injection molding or via the use of the fountain flow. Both cases are studied with scanning electron microscopy to visualize the structure in the skin layer. In addition, numerical modelling examples are presented to improve understanding of the morphologies that have been created with injection molding.
