Viscoelastic behavior of filled silicone elastomers and influence of aging in inert and hermetic environment

This article presents a series of experimental investigations on the viscoelastic behavior silica-filled and silver-filled silicone rubber unaged aged states. The study specific aging conditions relative to electronics industry is proposed in this work, namely hermetic, initially inert atmosphere, at high temperatures. Viscoelastic properties materials are measured through DMA tests. Strain sweep tests carried for characterization materials, frequency sweeps ambient temperature performed characterize aging-dependent behavior. As result studies, an generalized Maxwell model attempt describe evolution silicones due aging.
