What is Characterization of the Sharkskin Defect and its Development with the Flow Conditions** about?
Abstract We have studied the development of the sharkskin defect of a linear low density polyethylene, by using complementary experimental techniques. Roughness measurements have allowed to accurately characterize the surface of the extrudates. Flow birefringence observations have permitted to visualize the flow conditions inside the die. The development of the defect is strongly dependent on the temperature and quasi-independent on the geometry (die length, entry angle). Theoretical computations of the flow through the slit die have allowed the correlation of the amplitude of the defect with the stress distribution. Sharkskin defect appears as a continuous and regular phenomenon of surface degradation without intervention of wall slip.
