Title (EN) EXPANDABLE, EXPANDING-AGENT-CONTAINING GRANULES BASED ON HIGH-TEMPERATURE THERMOPLASTICS
(FR) GRANULÉS EXPANSIBLES CONTENANT UN AGENT D'EXPANSION À BASE DE THERMOPLASTIQUES HAUTE TEMPÉRATURE
(DE) EXPANDIERBARE, TREIBMITTELHALTIGE GRANULATE AUF BASIS VON HOCHTEMPERATURTHERMOPLASTEN
Abstract:
(EN) The invention relates to expandable, expanding-agent-containing granules based on high-temperature thermoplastics having a glass transition temperature according to ISO 11357-2-1999 of at least 180°C, the expandable, expanding-agent-containing granules containing at least one nucleating agent and having a bulk density according to DIN ISO 697:1982 in the range of 400 to 900 kg/m3 and a mass in the range of 1 to 5 mg/granule, a method for producing same and foam particles obtainable therefrom, having a glass transition temperature according to ISO 11357-2-1999 of at least 180°C, the expanded foam particles containing at least one nucleating agent and having a bulk density according to DIN ISO 697:1982 in the range of 10 to 200 kg/m3, to particle foams obtainable therefrom and to the use thereof to produce components for aviation.
(FR) La présente invention concerne des granulés expansibles contenant un agent d'expansion à base de thermoplastiques haute température ayant une température de transition vitreuse selon ISO 11357-2-1999 d'au moins 180 °C, les granulés expansibles contenant un agent d'expansion renfermant au moins un agent de nucléation et une densité apparente selon ISO 697:1982 dans la plage de 400 à 900 kg/m3 et une masse dans la plage de 1 à 5 mg/granulé. L'invention concerne également un procédé pour leur fabrication ainsi que des particules de mousse pouvant être obtenues avec ceux-ci et présentant une température de transition vitreuse selon ISO 11357-2-1999 d'au moins 180 °C, les particules de mousse expansées contenant au moins un agent de nucléation et présentant une densité apparente selon DIN ISO 697:1982 dans la plage de 10 à 200 kg/m3, ainsi que les particules de mousse pouvant être obtenues avec ceux-ci et leur utilisation pour fabriquer des pièces pour l'aviation.
(DE) Expandierbare, treibmittelhaltige Granulate auf Basis von Hochtemperaturthermoplasten mit einer Glasübergangstemperatur nach ISO 11357-2-1999 von mindestens 180°C, wobei die expandierbaren, treibmittelhaltigen Granulate mindestens ein Nukleierungsmittel enthalten und eine Schüttdichte nach DIN ISO 697:1982 im Bereich von 400 bis 900 kg/m3 und eine Masse im Bereich von 1 bis 5 mg/Granulat aufweisen, Verfahren zu deren Herstellung sowie daraus erhältliche Schaumstoffpartikel mit einer Glasübergangstemperatur nach ISO 11357-2-1999 von mindestens 180°C, wobei die expandierten Schaumstoffpartikel mindestens ein Nukleierungsmittel enthalten und eine Schüttdichte nach DIN ISO 697:1982 im Bereich von 10 bis 200 kg/m3 aufweisen, sowie daraus erhältliche Partikelschaumstoffe und deren Verwendung zur Herstellung von Bauteilen für die Luftfahrt..
