The expandable pellets can be recovered from the pelletizer (S), and the pellets can be recovered from the pelletizer (L).

  • Patent number: 8795562
    Abstract: The invention relates to a process and an apparatus for pelletizing polymer melts comprising blowing agent in a pelletizing chamber through which a liquid flows, its pressure being above the ambient pressure. In a first step, the polymer melt is injected into the pelletizing chamber, in a second step the polymer melt is cut via a cutting apparatus into individual pellets and, in a third step, the pellets produced in the pelletizing process are discharged with the liquid from the pelletizing chamber and are then isolated from the liquid.

  • Publication number: 20140162096
    Abstract: Disclosed herein are formulation components for the manufacturing of a flow frame structure that can be integrated in flowing electrolyte batteries. These formulation components for manufacturing flow frames may include, but are not limited to, polypropylene, glass fiber, a coupling agent and an elastomer. A mixing and extrusion process may be employed to formulate the material and produce pre-formulated pellets for the manufacturing of flow frames. As flow frames may be integrated with electrodes (or membranes), the disclosed flow frame formulation may achieve a desired Melt Flow Index (MFI) range and may allow an improved bonding between electrodes (or membranes) and flow frame, therefore, simplifying manufacturing process and achieving higher performance and longer lifetime of flowing electrolyte batteries.

  • Patent number: 8728368
    Abstract: The invention relates to a method for producing a semicrystalline polymer, said method comprising the following steps: producing a polymer melt from a crystallizable polymer; shaping particles and solidifying the polymer melt, the step of shaping the particles being carried out before or after solidification; cooling the particles; treating the particles to reduce their tendency to agglomerate; crystallizing the particles. The invention is characterized in that the treatment is carried out by shaking at a temperature T1 which is below the glass transition temperature of the polymer plus 10° C., i.e. T1<Tg+10° C.
