The polydispersity of the silicone sample is much greater and has a much more pronounced bimodality than the previously mentioned samples. The vast numerical majority of the particles are below 3 µm, with very few in the 20 µm -100 µm range, and then a significant portion in the 100 µm -1 mm range. The largest particles have low AR and high solidity which corresponds to their visual characterization as being boulder-like, with very little tortuosity. Interestingly, the smallest of the silicone particles provide examples of the largest AR and lowest solidity particles out of the mentioned samples, suggesting that there are different breakage mechanisms generating each size population.
