The test became necessary as older plasticines used in PDMS-plasticine mixtures characterized rheologically in Zwaan et al. (2020) became unavailable.
The material samples have been analyzed at the Laboratory for Experimental Tectonics at GFZ Helmholtz Centre for Geosciences, Potsdam (HelTec) using an Anton Paar Physica MCR 301 rheometer in a plate-plate configuration at room temperature (21˚C). Rotational (controlled shear rate) tests with shear rates varying from 10^-4 to 1 s^-1 were performed.
According to our rheometric analysis, the new materials cover a range of viscosities from 8E^+04 to 4E^+07 Pas. They exhibit shear thinning behavior with high power law exponents (n-number). For PP45-1, PP45-2 and PP100, the respective n-numbers are 10, 8 and 3 at shear rates above 10^-3s^-1 and around 2 below.
