Beschreibung
Zusammenfassung:	A method and compositions are described which improve extrusion- and creep- resistance of components for use in a high temperature applications including sealing elements and seal connectors among others. The method includes providing a composition having an aromatic polymer and a crosslinking compound, and subjecting the composition to a heat molding process to form the component and crosslink the aromatic polymer. La présente invention concerne un procédé et des compositions permettant d'améliorer la résistance à l'extrusion et au fluage de composants utilisables dans des applications haute température et, notamment, dans des éléments de scellement et des connecteurs étanches. Ledit procédé comprend les étapes consistant à utiliser une composition contenant un polymère aromatique et un agent de réticulation et à soumettre ladite composition à un processus de thermoformage afin de fabriquer le composant et de réticuler le polymère aromatique.
