Webprocessing of polyethylene processing. 1 During extrusion processing, flow from the die is characterized as pressure driven flow with a shear rate gradient present. The shear rate is defined as zero at the flow centerline, and is at a maximum at the metal die surface - polymer melt interface. Without a WebDec 20, 2024 · Polystyrene-based foams. Polystyrene (PS) is an amorphous polymer, and it has wide application area in polymer foam processing such as thermal insulation, packing material due to its low cost, ease of processing, resistance to moisture, and recyclability. Dow Chemical Company invented PS foams as “Styrofoam” in 1941.
