Dynamic properties of polymethylvinylsiloxane (PMVS) filled with surface-treated silica (SiO₂) were studied using an advanced rheometric expansion system (ARES). The results revealed that the coupling agent, bis (3-triethoxysilylpropyl) tetrasulfane (TESPT) exerted a pronounced effect on the storage modulus (G'), and the effect of TESPT involved a frequency-dependent relation.
