Colloidal properties of different carbon black (CB) grades

Fourier Transform Rheology – an innovative Tool for the Characterization of recovered Carbon Black

Colloidal properties of different carbon black (CB) grades represented by their structure and specific surface area were characterized before and after pyrolysis. Additionally, rubber compounds produced with these fillers were investigated by Fourier Transform (FT) Rheology, since the nonlinear, rheological behavior of filled elastomers under specific conditions is associated with the filler-polymer interaction. For comparison, […] more...

Simulation unterstützt Prozessverständnis

Simulation for 2K-Processing

Die Konstruktion von Spritzgieß-Werkzeugen für Mehrkomponentenanwendungen erfordert die ganze Erfahrung der Werkzeugbauer. Wenn es sich dabei noch um eine Thermoplast-plus-Flüssigsilikon-Anwendung handelt, ist eine sorgfältige thermische Auslegung für einen stabilen Prozess unerlässlich. Zur Unterstützung dieser Auslegung kommen moderne Simulationsansätze zum Einsatz, um so die Werkzeugänderungen auf ein Minimum zu reduzieren. Der Beitrag zeigt diese Möglichkeiten anhand des “Butterfly“ - eines Handyhalters aus Polycarbonat und Flüssig- silikonkautschuk, der für die K 2019 designt wurde. more...
