Abstract
(DE)
Die vorliegende Erfindung betrifft ein geschäumtes Granulat umfassend ein thermoplastisches Polyurethan erhältlich oder erhalten durch Umsetzung einer Polyisocyanatzusammensetzung (IZ), die mindestens ein aliphatisches Diisocyanat mit einem zahlenmittleren Molekulargewicht kleiner als 200 g/mol enthält, mindestens einem Kettenverlängerer (KV1), und einer Polyolzusammensetzung (PZ), sowie ein Verfahren zur Herstellung eines derartigen geschäumten Granulats. Die vorliegende Erfindung umfasst weiterhin die Verwendung eines erfindungsgemäßen geschäumten Granulats zur Herstellung eines Formkörpers.
(EN)
The present invention relates to an expanded granulate comprising a thermoplastic polyurethane obtainable or obtained by reacting a polyisocyanate composition (IZ), containing at least one aliphatic diisocyanate with a number-average molecular weight of less than 200 g/mol, with at least one chain extender (KV1) and a polyol composition (PZ), and also to a method for producing an expanded granulate of this type. The present invention also relates to the use of an expanded granulate according to the invention for producing a moulded body.
(FR)
La présente invention concerne un granulé expansé comprenant un polyuréthane thermoplastique obtenu ou pouvant être obtenu par mise en réaction d'une composition de polyisocyanate (IZ), contenant au moins un diisocyanate aliphatique présentant une masse moléculaire moyenne en nombre inférieure à 200 g/mol, d'au moins un allongeur de chaîne (KV1) et d'une composition de polyol (PZ). L'invention concerne également un procédé de production d'un tel granulé expansé. La présente invention concerne en outre l'utilisation d'un granulé expansé selon l'invention pour la production d'un corps moulé.
