Abstract
In the extrusion of polyethylene (PE), fluoropolymer-processing additives (PPA) are used to eliminate the surface defect known as sharkskin by coating the die wall and inducing slip at the PPA/PE interface. We describe a method to carry out in situ measurements of the coating kinetics that is based on the optical phenomenon of frustrated total internal reflection (F-TIR). The estimated coating thickness is found to be significantly lower (60-350 nm) than reported previously (5-15 mm). The coating mechanism is proposed to have origins at the die entrance.Proceedings Title
