Abstract
The investigation of the elimination of sharkskin using polymer processing aids (PPA) requires the consideration of factors such as: PPA domain size, operational shear rate and matrix/PPA viscosity ratio. In this work, the role of PPA droplet size in the elimination of surface melt fracture was investigated. The parameters monitored were the die entrance pressure, the PPA coating thickness and the extrudate appearance. We found a substantial enhancement in coating thickness and speed upon increasing the droplet size.Proceedings Title
