Mechanical properties of bulk Sylgard 184 and its extension with silicone oil

Abstract Due to its simple curing and very good mechanical properties, Sylgard 184 belongs to the most widely and frequently used silicones in many industrial applications such as microfluidics and microengineering. On top of that its mechanical properties are further controllable through the curing...
