Abstract
High levels of inorganic filler, processing fluid and silicone polymer are compounded and devolatilized into homogeneous filled compositions with requisite reinforcing properties and levels of volatiles. In the method, a filler, processing fluid and silicone polymer are mixed in a first compounding apparatus to produce a dispersed composition containing volatiles. The dispersed composition is then compounded in a long extruder having an L/D ratio of greater than 50 to devolatilize the dispersed composition.
