EFFECTS OF PARTICLE SIZE AND SIZE DISTRIBUTION ON THE MECHANICAL PROPERTIES OF EPDM/SILICA VULCANIZATES M.N.
This fact could explain why the mechanical properties of the EPDM filled with Si-200 are not in between the values of the compounds filled with Si-150 and Si-250.
During the last years, the effects of different types of fillers on rubber compounds have been studied, in search of improvements on its physical and mechanical properties.
These values are affected by several factors such as surface reactivity, which determines the polymer-filler interaction, aggregates, size and shape of the particles, structure and filler particle dispersion [7].
