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...
