| 20080281004 | Expandable Polystyrene Granulates With a Bi- or Multi-Modal Molecular-Weight Distribution - Expandable pelletized styrene polymer materials with at least bi- or multimodal molecular weight distribution, to a process for their preparation, and to use for producing moldable-foam moldings. | 11-13-2008 |
| 20090039537 | Method for the Production of Expandable Styrol Polymers Having Improved Expandability - A process for producing expandable styrene polymers (EPS) having improved expandability, wherein from 0.1 to 1% by weight, based on the styrene polymer, of a free-radical former is metered into a styrene polymer melt containing blowing agent at a melt temperature in the range from 150 to 220° C. and the melt is extruded through a die plate with subsequent underwater pelletization. | 02-12-2009 |
| 20090108480 | METHOD AND DEVICE FOR GRANULATING POLYMER MELTS CONTAINING BLOWING AGENT - 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. This process also comprises at least one of the following steps:
