Description: The surface shows periodic ridges at right angles to the flow direction. These are indicative of flow instability and a periodic slipping of the melt at the die wall. It also shows surface scratches which are typical of polymer surfaces. Hard abrasive particles, dragged across the surface, have displaced material to form grooves and ridges.
