    摘要: The present invention relates to the use of a specific compound as a fluidizing agent or as a fluidizing agent precursor in the molten state for a composition including a thermoplastic polymer, in particular a polyamide. The invention further relates to a method for preparing a polyamide article in which the viscosity, in the molten state, of a composition including the polyamide is decreased. The fluidizing agent can further enable the production of an article which has an unreduced density and/or in which the mean molar mass of the polymers of the composition is increased.

    摘要: A melt cooler and valving system for an underwater pelletizer has a diverter valve that facilitates multiple modes of melt processing. The cooler has a cooler inlet line that conveys the melt to the cooler, and a cooler outlet line that conveys the cooled melt from the cooler. The diverter valve is configured to convey the melt to and from the cooler during a cooling mode of operation, to convey the melt around the cooler during a bypass mode of operation, and to drain the melt from the cooler and the diverter valve during a drain mode of operation. The diverter valve is compact and therefore contains a minimum of product inventory. The valve is streamlined and direct in its bypass mode, and includes a drain capability to allow for faster, easier cleaning of the process line, which in turn provides a fast changeover time with less lost product.

    摘要: An apparatus and process to maintain control of the temperature of low-melting compounds, high melt flow polymers, and thermally sensitive materials for the pelletization of such materials. The addition of a cooling extruder, and a second melt cooler if desired, in advance of the die plate provides for regulation of the thermal, shear, and rheological characteristics of narrow melting-range materials and polymeric mixtures, formulations, dispersions or solutions. The apparatus and process can then be highly regulated to produce consistent, uniform pellets of low moisture content for these otherwise difficult materials to pelletize.

    摘要: A device and a method for producing pellets from a melt, having a perforated plate with melt nozzles located therein from which nozzles the melt emerges. The perforated plate is located opposite a cutter arrangement with a cutter head with at least one blade, and a cutter shaft driven by a motor so that the at least one blade passes over the melt nozzles in the perforated plate in a rotating manner and in doing so severs pellets of the melt material emerging there. The cutter shaft is at least axially displaceable relative to a process chamber housing by means of at least one adjustable bearing. The position of the at least one blade can be determined and adjusted using a position sensing and adjusting device.
