  • Process for the Cutting of Thermoplastic Polymers Downstream of a Water-Ring Die
    Publication number: 20080217804
    Abstract: Process for the production of substantially cylindrical pellets of vinyl-aromatic (co)polymers, leaving a water-ring extrusion die, wherein the extrusion is effected so that the length/diameter ratio of the pellet ranges from 1.3 to 2 and the diameter of the (base) ranges from 2 to 3.2 mm, with a flow-rate of the polymer, per hole of the die, ranging from 4 to 20 kg/h.
