Kontinuierliche Herstellung von Hitze-vulkanisierbarer Silikon Zusammensetzung

摘要

High levels of treated fumed silica, processing fluid and high molecular weight silicone polymer are continuously compounded into a homogeneous silica filled heat-vulcanizable silicone composition by forming a premix in a continuous annular layer mixer (12,52,54) and continuously discharging the premix into a compounding apparatus (14,56,58) for compounding to form the filled heat-vulcanizable silicone composition.
