More Information
Summary:The present invention relates to polyamide foam particles comprising (A) from 5 to 99.9 wt.-% of at least one polyamide, (B) from 0.1 to 5 wt.-% of at least one stabilizer, selected from secondary arylamines (C) from 0 to 49 wt.-% of further additives, wherein the sum of the components (A) to (C) is 100 wt.-%, a process for preparing the polyamide foam particles and polyamide particle foam moldings made therefrom. La présente invention concerne des particules de mousse polyamide comprenant (A) de 5 à 99,9 % en poids d'au moins un polyamide, (B) de 0,1 à 5 % en poids d'au moins un stabilisant, choisi parmi les arylamines secondaires, (C) de 0 à 49 % en poids d'autres additifs, la somme des constituants (A) à (C) étant de 100 % en poids, un procédé de préparation desdites particules de mousse polyamide et des objets moulés en mousse de particules de polyamide fabriqués à partir de celles-ci.
