| description | A process for continuous extrusion of a high molecular weight polymeric material having high reduced specific viscosity is provided. Compaction of the high molecular weight polymeric material in the required form of tape/profile in molten form is achieved before the exit of the high molecular weight polymeric material from the extruder at the distal end without the use of a die-head. The elimination of the die-head as part of extruder helps in overcoming the processing limitations caused by very high reduced specific viscosity and flow resistance of the polymer melt.
La présente invention concerne un procédé d'extrusion en continu d'un matériau polymère de masse moléculaire élevée présentant une viscosité spécifique réduite. Le compactage dudit matériau polymère de masse moléculaire élevée sous la forme requise de ruban/profilé sous une forme fondue est réalisé avant la sortie dudit matériau polymère de masse moléculaire élevée de l'extrudeuse au niveau de l'extrémité distale sans utiliser de tête de filière. L'élimination de la tête de filière en tant que partie de l'extrudeuse aide à surmonter les limitations du traitement occasionnées par des propriétés de viscosité spécifique et de résistance à l'écoulement hautement réduites du polymère fondu. |
