Thickness variation in coextruded layers : effect of polymer viscoleasticity on layer unformity
Source abstract
Abstract
The effect of polymer viscoelasticity on the uniformity of layer thickness within multilayer coextruded structures was investigated. The study was carried out using a unique feedblock that produces a coextruded structure consisting of an array of 49 individual polymer strands (7 rows x 7 columns) embedded within a polymer matrix. The strands trace the flow paths within different types of dies and provide information about the movement within a flowing viscoelastic polymer stream.
